Parent material - Few soils weather directly from the underlying rocks. These residual soils have the same general chemistry as the original rocks. More commonly, soils form in materials that have moved in from elsewhere. Materials may have moved many miles or only a few feet. Windblown loess is common in the Midwest. It buries glacial till in many areas. Glacial till is material ground up and moved by a glacier. The material in which soils form is called “parent material.” In the lower part of the soils, these materials may be relatively unchanged from when they were deposited by moving water, ice, or wind
Sediments along rivers have different textures, depending on whether the stream moves quickly or slowly. Fast-moving water leaves gravel, rocks, and sand. Slow-moving water and lakes leave fine textured material like clay and silt when sediments in the water settle out.
Climate - Soils vary, depending on the climate. Temperature and moisture amounts cause different patterns of weathering and leaching. Wind redistributes sand and other particles, especially in arid regions. The amount, intensity, timing, and kind of precipitation influence soil formation. Seasonal and daily changes in temperature affect moisture effectiveness, biological activity, rates of chemical reactions, and kinds of vegetation.
Topography - Slope and aspect affect the moisture and temperature of soil. Steep slopes facing the sun are warmer. Steep soils may be eroded and lose their topsoil as they form. Thus, they may be thinner than the more nearly level soils that receive deposits from areas upslope. Deeper, darker colored soils may be expected on the bottom land.
Biological factors - Plants, animals, microorganisms, and humans affect soil formation. Animals and microorganisms mix soils and form burrows and pores. Plant roots open channels in the soils. Different types of roots have different effects on soils. Grass roots are fibrous near the soil surface and easily decompose, adding organic matter. Taproots open pathways through deeper layers. Microorganisms affect chemical exchanges between roots and soil. Humans can mix the soil so extensively that the soil material is again considered parent material.
The native vegetation depends on climate, topography, and biological factors, plus many soil factors such as soil density, depth, chemistry, temperature, and moisture. Leaves from plants fall to the surface and decompose on the soil. Organisms decompose these leaves and mix them with the upper part of the soil. Trees and shrubs have large roots that may grow to considerable depths.
Time - Time is also a component for the other factors to interact with the soil. Over time, soils exhibit features that reflect the other forming factors. Soil formation processes are continuous. Recently deposited material, such as the deposition from a flood, exhibits no features from soil development activities. The previous soil surface and underlying horizons become buried. The time clock resets for these soils. Terraces above the active floodplain, while similar to the floodplain, are older land surfaces and exhibit more development features.
These soil-forming factors continue to affect soils even on stable landscapes. Materials are deposited on their surface and blown or washed away from the surface. Additions, removals, and alterations are slow or rapid, depending on climate, landscape position, and biological activity.
Answer:
Soils differ from one part of the world to another, even from one part of a backyard to another. They differ because of where and how they formed. Five major factors interact to create different types of soils:
CLIMATE
ORGANISMS
RELIEF (LANDSCAPE)
PARENT MATERIAL
TIME
Climate, Temperature and moisture influence the speed of chemical reactions, which in turn help control how fast rocks weather and dead organisms decompose. Soils develop faster in warm, moist climates and slowest in cold or arid ones.
Rainfall is a part of climate
Rainfall is one of the most important climate factors in soil formation.
Organisms—Plants root, animals burrow, and bacteria eat – these and other organisms speed up the breakdown of large soil particles into smaller ones. For instance, roots produce carbon dioxide that mixes with water and forms an acid that wears away rock. Learn more on our Soil Biology page!
Termites can radically change a landscape.
Termites can generate mounds in the soil that are three stories tall!!!
Relief (landscape)—The shape of the land and the direction it faces make a difference in how much sunlight the soils gets and how much water it keeps. Deeper soils form at the bottom of a hill because gravity and water move soil particles down the slope.
Soil is different depending on where on a slope it is taken
Soils are different depending on the location in the slope that they are located.
Parent material—Every soil “inherits” traits from the parent material from which it formed. For example, soils that form from limestone are rich in calcium and soils that form from materials at the bottom of lakes are high in clay. Every soil formed from parent material deposited at the Earth's surface. The material could have been bedrock that weathered in place or smaller materials carried by flooding rivers, moving glaciers, or blowing winds. Parent material is changed through biological, chemical and environmental processes, such as weathering and erosion.
Soil forming at a volcano in real time
These are soils forming in real time from the side of the volcano. They form into rock first, then weather into fertile soil.
Time—All of these factors work together over time. Older soils differ from younger soils because they have had longer to develop. As soil ages, it starts to look different from its parent material. That is because soil is dynamic. Its components—minerals, water, air, organic matter, and organisms—constantly change. Components are added and lost. Some move from place to place within the soil. And some components are totally changed, or transformed.
WHO STUDIES ABOUT SOIL AND HOW IT FORMS?
Evaluating a Soil Profile
Evaluating a soil profile can tell a lot of stories how soils form, and what they can be used for.
Soil pedologists and morphologists study how different soils form. How do soils form? How is this important for soil management? What impact do humans have on the evolution and formation of soils?
SOIL MAPPING
Did you know that the soil under your feet has a name (there's an app for that)? Soils, like species, can be identified through a process of taxonomy. Taxonomy groups soils with similar features into the same category. There are over 25,000 different named soils in the US. People who map soils generate digital copies of the world beneath our feet, and draw lines to estimate boundaries between soil with different names.
This is an example soils map
This is an example of a soils map over a small area in Wisconsin. The little letter are different soil series
Disturbed Soils
When humans build buildings and roads they change soils, often removing the surface soil and drastically changing the areas. When this change happens, soil formation starts to change. People who study disturbed soils map how these soils respond to human manipulation.

Describe the effects of weathering and mass movement on a cliffed coastline.
Answer:
Weathering is the process whereby larger rocks are broken down into smaller particles. Factors that makes the process of weathering and mass movement happen include animal activities in the soil, water, wind etc.
Due to the presence of animal and plant on ocean cliffs, their activities help loosen the rock materials. Some of the loosened rocks fall back into the ocean.

Describe the differences and causes of tornades and thunderstorms.
please help due today!!!!!
Answer:
A thunderstorm is a fast-rising column of air which produces heavy rain, wind, lightning, and sometimes hail. A tornado is a violently rotating column of rising air which is spawned by and is always attached to the bottom of a rotating thunderstorm. Thunderstorms last a lot longer than tornadoes.
Explanation:
A thunderstorm is a storm with strong-enough updrafts and downdrafts that strong static electricity charges develop, leading to lightning. The extremely-rapid heating of air during a thunderstorm produces thunder.
Tornadoes develop during some, but not all, thunderstorms. They are a rapidly-spinning updraft, reducing air pressure sufficiently around their base that buildings can explode due to the outside air pressure now being considerably less than the inside air pressure. They also hurl debris long distances. They are much more destructive than regular thunderstorms.

En un esquema señala cuáles son los diferentes ramas industriales y su importancia
La respuesta correcta a esta pregunta abierta es la siguiente.
Las diferentes ramas industriales son las siguientes. Primero, lo que se conoce como la industria básica. Luego, la industria manufacturera y la industria de la transformación. Cuando hablamos de la industria básica estamos hablando de las empresas que se encargan de extraer la materia prima y los recursos naturales, como lo hacen las empresas petroquímicas o las que extraes los metales y minerales de la tierra. Cuando se han extraído los materiales, se mandan a fábricas para que los transformen en productos. Ahí es donde entra la industria de la transformación, que convierte los recursos naturales en textiles. Finalmente la industria manufacturera fabrica la ropa que nos ponemos todos los días. O cualquier otro producto de consumo público.
La importancia de estas industrias es que son vitales para la vida económica de un país. Si no existieran, no habría forma de transformar la materia prima o recursos naturales en los productos que usamos todos los días.

An earthquake is best described as a
Answer:
a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action.
Explanation:
An earthquake is the shaking of the Earth's surface caused by a sudden release of energy in the Earth's lithosphere, which generates seismic waves.
What is Earthquake ?It is also referred to as a quake, tremor, or temblor. Earthquakes can range in strength from those that are so small that no one can feel them to those that are powerful enough to throw things and people into the air, destroy vital infrastructure, and devastate entire cities.
The number, kind, and size of earthquakes that occur in a region over a specific time period is known as its seismic activity. The average rate of seismic energy release per unit volume is what is known as seismicity at a specific region on Earth.
Tremors, which are not earthquakes, are also referred to as seismic rumbling. Earthquakes cause the ground to shake, move, or otherwise be disturbed at the Earth's surface. The bottom may be sufficiently moved to generate a tsunami when a big earthquake's epicenter is offshore. Landslides can also be brought on by earthquakes.

Estimate the distance of a fading white dwarf supernova of luminosity 108lsun whose apparent brightness is comparable to that of a bright cepheid variable star 100 million light-years from earth.
Answer:
The supernova is a fraction of 0.7 of the size of the observable universe which is 10 billion light years away.
Explanation:
Apparent brightness(AB) = luminosity(L) / 4πr²
∴ Luminosity(L) = Apparent brightness(AB) × 4πr²
Ratio of the luminosity of cepheid and supernova with the same brightness will be written as;
[tex]\frac{L_{cepheid}}{L_{supernova}} = \frac{AB_{cepheid}(4\pi r^2)}{AB_{supernova}(4\pi r^2)}[/tex]
[tex]= \frac{AB_{cepheid}(r^2_{cepheid})}{AB_{supernova}(r^2_{supernova})}[/tex]
[tex]\frac{(r^2_{cepheid})}{(r^2_{supernova})}[/tex]
Therefore, [tex]r_{supernova} = r_{cepheid}\sqrt{\frac{luminosity_{cepheid}}{luminosity_{supernova}} }[/tex] ...................(a)
Since we already have [tex]r_{cepheid}[/tex] as 100 million light year, substitute for luminosity of supernova and luminosity of cepheid as 10⁸[tex]L_{sun}[/tex] and 10,000[tex]L_{sun}[/tex] respectively in equation (a)
[tex]r_{supernova} = 100 million \sqrt{\frac{10^8L_{sun}}{10,000L_{sun}} }[/tex] ==> 10 billion light year
the ratio of the distance to the size of the universe:
Supernova / Observable Universe = (10 / 14) billion light years
Supernova / Observable Universe = 0.7
The supernova is a fraction of the size of 0.7 of the size of the viewable universe that is 10 bn light years away.
What is supernova and how far is it. ?The supernova is a very powerful and luminous Steller explosion and is a transitional astronomical event and take place ducting the evolution and is one of the stages of the massive star. Triggered by the leakage of the gases.
The distance of the fading of a white dwarf supernova of brightness is 108 sun and has brightness as comparable to that star of the brightest Cepheid. The star has a variable of 100 million light years form earth. Thus distance of the nearest supernova is 50 billion light years and the observable is 10 billion.
