verticle transport of materials within soil occurs by

Answers

The physical and chemical disintegration of the earth's rocks, brought on by air factors, is the first step in the production of soil.

These procedures, together referred to as weathering, chip away pieces of rock, changing its natural physical and chemical properties. The rate of chemical reactions is influenced by temperature and moisture, which in turn affects how quickly rocks weather and dead animals degrade. In warm, wet regions, soil development happens more quickly than in cold or arid ones. One of the most crucial climatic variables for the formation of soil is rainfall. Five components make up soil: minerals, soil organic matter, living things, gas, rocks, and water. The process of genesis of soil, sometimes referred to as pedogenesis, is controlled by the effects of geography, environment, and history. The primary determinants of soil formation are terrain features, parent material, climate, flora, and other life-forms, as well as time separate from human activity.

How do you treat 2nd and 3rd degree burns?

Answers

To treat second-degree burns, a doctor could advise an antibiotic cream or other lotions or ointments. More severe therapies, such as intravenous (IV) antibiotics to prevent infection or IV fluids to replenish fluids lost when the skin was burned, may be required for third- and fourth-degree burns.

For many second-degree burns, home care is sufficient to promote healing and stop further complications. It's crucial to maintain cotton garments in the affected region. Wear a peaked cap or wide-brimmed hat when you're outside in the sun if the burn or scald is on your face.

Answers

PLEASE MARK ME AS BRAINLIEST

The more solar radiation is absorbed, the more heat is re-radiated, and the temperature of the atmosphere goes up. Solar radiation that is reflected back into space by Earth's surface or atmosphere does not add heat to the Earth system. Absorbed radiation is transformed into heat.

what conclusion can you draw about the impact of urban heat islands on climate change? support your ideas with two pieces of evidence.

Answers

Urban heat islands (UHIs) are areas of increased temperatures as a result of human activities, such as the burning of fossil fuels, that contribute to the overall warming of the planet.

UHIs can occur in both urban and rural areas, but tend to be more pronounced in urban areas due to the presence of more buildings and other infrastructure. The first piece of evidence that supports the conclusion that UHIs have an impact on climate change is the fact that UHIs can significantly contribute to the warming of the planet.

UHIs can produce a heat island effect, which is the process by which the air near the ground can be heated up to 10°F to 20°F above the surrounding area. This creates a localized hot spot that can have a significant impact on the overall temperature of the planet.

The second piece of evidence that supports the conclusion that UHIs have an impact on climate change is the fact that UHIs can create localized areas of more intense precipitation. This is due to the fact that the air near the ground is heated to a greater degree, which causes it to rise more quickly and cause more intense precipitation. This increased precipitation can lead to an increase in the risk of flooding, particularly in urban areas, which can have a cascading effect on the local environment and the overall climate.

Wat type of mountains are generally made up of undeformed rocks?

Answers

The original rocks transform into metamorphic rocks in those regions of complicated mountains where the crust is subjected to strong compressive forces, extremely high temperatures, and high pressures. Additionally, the complex mountains may receive an injection of igneous materials (made from magma). 

Mountain ranges, especially those found on continents, are closely related to metamorphic rocks. More metamorphic rocks are exposed at the surface in older, heavily eroded mountain chains than in younger chains. As a mountain chain is generated by folding and compression, metamorphism takes place deep inside the chain.

Carol's father found pieces of elk skull and the bones of some other unidentified animals. Carol found an insect encased in amber and her little brother found two or three shark's teeth. Based on the family's fossil evidence, what can we hypothesize about the past history of the camp site?.

Answers

Answer: We theorize that the campsite was once under water because of the shark teeth.

Explanation: The Elk and insect in amber are new by fossilization standards so were ignore them as part of the current era. The Shark teeth tell us that it's been underwater since shark swim in the ocean. Therefore the park used to be submerged under the ocean a long time ago.

Carol’s family found pieces of elk skull and some unidentified animals, an insect encased in amber, and shark’s teeth. Based on their fossil evidence, the correct hypothesis about the campsite is: D. It was once underwater.

How to tell if a land was once underwater?

Earth constantly changes, from the landscape to the weather or climate. The tectonic process within Earth’s plate causes the uplift or subsidence of rock materials. It forms mountains, lands, lakes, seas, to oceans. By looking at the finding of fossil evidence, we can tell if a land was once underwater.

What is a fault?

This movement may happen suddenly, like an earthquake, or it may happen gradually, like creep. From a few centimetres to millions of kilometers, faults can vary in length.

When tensional stress causes the blocks to shift vertically, a normal fault occurs, and the fault plane is between 45 and horizontal. Rocks start pulling apart as the result of strain.

Compressional stress leads to inverse fault. The fault runs between 0 and 40 degrees, and the boulders are brittle by design and therefore will roll over one another.

Another type of reverse fault seems to be a thrust fault. Typically, the fault angle is less than 45 degrees. In such circumstances, the older rocks will just be discovered above the youths due to the pushing of the former over the later.

Slow down

The less dense water will not be able to sink and circulate through the deep ocean as it does. This will disrupt or stop the Conveyor Belt.

Melting ice causes fresh water to be added into the ocean water which is usually salty. The fresh water added makes the seawater less dense which causes the slowing down.

There are a couple of effects of melting glaciers which include; driving up global temperatures which hastens the retreat of glaciers around the world, it has also contributed to rising seas when the melted glaciers drains into oceans.

Answers

The primary source of the substance lime is limestone, a form of carbonate sedimentary rock composed primarily of calcium carbonate (CaCO3).

The minerals calcite and aragonite, which are various crystal forms of CaCO3, make up the majority of its limestone. When these minerals separate from water that has dissolved calcite, limestone is created. Both biological and nonbiological activities can contribute to this, while biological processes—like the buildup of corals and shells in the sea—have probably been more significant during the past 540 million years. Fossils found in limestone frequently reveal details about ancient ecosystems and the development of life. The majority of limestone was created in shallow marine habitats, such as continental shelves or platforms, however minor amounts were also created in numerous other locations. There is a lot of secondary dolomite, which is created when limestone undergoes chemical change.
