Answer:
When atoms combine to make a compound, energy is always given off, and the compound has a lower overall energy. When a chemical reaction occurs, molecular bonds are broken and other bonds are formed to make different molecules. For example, the bonds of two water molecules are broken to form hydrogen and oxygen.
Explanation:
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.

Which of the following statements best describe why the Dead Sea's water levels are decreasing?
The Dead Sea is the final destination for the water of the Jordan River; there is no outlet.
High levels of salt make the Dead Sea a poor environment for aquatic life.
More water is being siphoned off the Jordan River for agriculture.
The extraction of numerous minerals has left the sea at risk of shrinking.
Answer:
Sorry for being late but the answer would be C: More water is being siphoned off the Jordan River for agriculture.
Explanation:
The Jordan River flows into the Dead Sea, 200 miles long. Although it is true that minerals are extracted from the Dead Sea, it is not a factor to water shortage. More water has been used from the Jordan River to irrigate and for agriculture, thus less water reaches the Dead Sea. Hope this helps :)

Should be C.

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.

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.

Which claim explains how pyroclastic material differs from lava?
A.Unlike lava, pyroclastic material erupts onto Earth’s surface.
B.Unlike lava, pyroclastic material erupts from shield volcanoes.
C.Unlike lava, pyroclastic material is associated with explosive eruptions.
D.Unlike lava, pyroclastic material is associated with nonviolent eruptions.
Answer: A.Unlike lava, pyroclastic material erupts onto Earth’s surface.
Explanation:
The pyroclastic material is the one that erupts with an explosive volcanic eruption like that of lava eruption. The pyroclastic erupts by ejecting the fragments, resulting in ashfall deposits, it flows out with an ash deposit on the surface of the earth. The fragmented material spreads on the Earth's surface. The fragments are of grain size.

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.

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.
Which kind of seismic waves cause most of the damage associated with earthquakes?
1:L
2:P
3:S
4:E
Answer: S
Explanation:
S waves are more dangerous than P waves because they have greater amplitude and produce vertical and horizontal motion of the ground surface. The slowest waves, surface waves, arrive last. They travel only along the surface of the Earth. There are two types of surface waves: Love and Rayleigh waves.
