The process of convection in the Earth's mantle plays a significant role in the formation of mountains and the temperature in the surface ground.
Formation of Mountains: Convection in the Earth's mantle causes the movement of tectonic plates, which can lead to the formation of mountains. When two tectonic plates collide, one plate is forced beneath the other, leading to the uplift and formation of mountains.
Temperature in the Surface Ground: Convection in the Earth's mantle also plays a role in the temperature of the surface ground. As hot material from the mantle rises, it can create hot spots on the Earth's surface, which can lead to increased volcanic activity and higher surface temperatures. Additionally, the heat generated by convection can contribute to the overall warming of the Earth's surface.
Plate boundaries: The convection cell causes the movement of tectonic plates at the boundary of the plates. The movement of the tectonic plates causes the formation of mountains, volcanoes, and earthquakes.
Plate subduction: As a plate sinks into the mantle, it causes the rock to heat up and melt. This creates magma that rises to the surface and can create volcanic activity.
Overall, the process of convection in the Earth's mantle plays a major role in shaping the Earth's surface and affecting the temperature in the surface ground. It causes the movement of tectonic plates, the formation of mountains, and volcanic activity.

overgrazing
overfishing
climate change
population growth
logging
Answer:
Logging,pollution,population growth
Explanation:
Logging - Logging, as in most parts of the world is something that destroys the forests, and even if it is regulated properly and new trees are planted when the old ones are taken down, the small trees need much longer period to fully grow and replace the trees that are taken down, while the demand is growing more and more.
Pollution - As in most things, the pollution, mainly the soil and water pollution, are directly damaging the forests and contribute to their dying out because of high intake of toxins.
Population growth - Because of the ever growing population in the United States and the ever increasing demand for new living facilities, the towns and cities are expanding, and this means clearing the forests as well so that the construction work can take place.

An almond or lens-shaped cloud which appears stationary, but which may contain winds of 50 knots or more, is referred to as?
An almond or lens-shaped cloud which appears to be stationarily is referred to as Lenticular Clouds.
What are these Lenticular clouds?
Almond- or lens-shaped clouds known as lenticular clouds are typically found on the leeward side of a mountain range. Despite appearing immobile, lenticular clouds may contain winds of 50 knots or more.
When the air is steady and winds are blowing across hills and mountains from the same or a comparable direction at different heights across the troposphere, these lens-shaped orographic wave clouds emerge.
Base elevation: 6,500–16,500 ftShape: Layers that are curved, like flying saucersAltocumulus lenticularis is Latin for "like a lens."No precipitationHow do Lenticular clouds form?
In certain situations, air blowing across a mountain range can create a train of enormous standing waves in the air downstream, similar to how ripples occur in a river when water runs over an obstruction.
If there is enough moisture in the air, the wave's upward motion will cause water vapour to condense, giving lenticular clouds their distinctive shape.

Which of the following orbit planets?
OA. Moons
OB. Dwarf planets
OC. Asteroids
OD. Comets
Answer:
A. Moons
Why do moons orbit planets instead of the sun?The basic reason why the planets revolve around, or orbit, the Sun, is that the gravity of the Sun keeps them in their orbits. In the same way, the Moon orbits the Earth because of the pull of Earth's gravity, the Earth orbits the Sun because of the pull of the Sun's gravity.
The moons are also pieces of the planets that could not be put together during planet creation and remained nearer to their respective planets as a result.
The gravitational force is inversely proportional to the square of the distance between the masses, as stated by the law of gravity. In case of the sun and the moons, the distance is greater than that between the planets and the moons. As a result, there is less gravitational pull between the planet and the moon. The moon is therefore considerably more likely to rotate around its own planet than the sun.

1) Locate a primary source describing the geography and environment of the park. This source should have been written either before, or close to, the time that the park was founded.
A primary source is an original document or artifact that comes from the period of time being studied. Someone from that time period actually wrote, created, or used the object being studied.
Examples of primary sources are diaries, letters, oral histories, and eyewitness accounts.
When searching for a source, consider looking for something written by John Muir, Lewis and Clark, or Theodore Roosevelt. Each of these men wrote descriptions of many of the parks that are protected today.
2) Paraphrase the author’s description in the comparison chart. Be sure to record key characteristics of the geography; you will want specific details for your writing.
To paraphrase information:
Reword the passage from source material in your own words.
Aim for a shorter and slightly condensed version of the original material.
Attribute material to the original source.
3) Locate a secondary source describing the geography and environment of the park today.
Secondary sources are documents written after the event occurred. They provide a secondhand account of the event or topic. Secondary sources often contain more analysis, or even conclusions, regarding the events or topics discussed.
Examples of secondary sources are newspaper and journal articles, academic textbooks, encyclopedias, reference books, and other nonfiction books and websites.
4) Paraphrase the author’s description in the comparison chart. Record specific details and pay close attention to similarities and differences you notice between this source and your previous one.
Then, using your completed comparison chart, create a multimedia comparison of the similarities and differences between the two sources. Your comparison should have at least three sections or paragraphs and can be in the format of a wiki, a Web site, or an interactive poster on the national park.
In the first paragraph or section, discuss the similarities between the descriptions in your sources about the park. Your first paragraph should have at least one properly cited quote and be 70 words long.
In a new paragraph or section, contrast the descriptions of the park in the two sources, explaining what has changed since the park has opened. Your paragraph should have at least one properly cited quote and be 70 words long. Include a properly cited picture of the park to add to your information.
In the final section, analyze the changes that occurred in the park and what caused them. Your paragraph should be well-developed, with complete and complex sentences, and at least 70 words long. Add either a source or a relevant picture to your project that enhances the quality of your presentation. Remember to properly cite your sources.

Answer:
if you send your soil out for a test and find out that it contains 75% silt and 25% clay, what kind of soil do you have?
Pure loamExplanation:
Pure loam is considered to be the best kind of soil for a farm or garden and is often defined as a soil with roughly equal proportions of sand, silt, and clay.
The best type of soil for growing plants is called loam soil. It is essentially a mix of soil that often contains equal amounts of clay, silt, and sand and offers the advantages of each with few drawbacks.
What are the features of loam soil?Sand, silt, and clay are present in loam soils in amounts that strike a balance between their stickiness and non-stickiness, making them moldable but not sticky.
Sand, clay, and silt particles combine to form loamy soils, which are thought to be the most fertile type of soil.
Sand lessens compaction and enhances drainage, while clay and silt particles enhance moisture retention. Neither do loamy soils become waterlogged in the winter, nor do they dry out in the summer.
Therefore, Pure loam, which is sometimes described as soil with nearly equal amounts of sand, silt, and clay, is thought to be the greatest sort of soil for a farm or garden.
