The primary agent of contact metamorphism is:

(B) Heat

<h3>Further explanation</h3>

Contact metamorphic rocks are formed due to the influence of magma intrusion at very high temperatures. The temperature is very high because it is located close to the magma. The word metamorphic was taken from the Greek words meta and morph. Meta means change, and morph means form. So, we can conclude that metamorphism is the process of changing rock form.

The primary agent of contact metamorphism is the heat. High temperatures come from magmas injected in the surrounding solid rock. Marble is one of the examples of contact metamorphic process. It is created from limestone that has been subjected to heat.

Besides the contact metamorphism, there are two other processes such as dynamo metamorphism, and pneumatolytic metamorphism. Dynamo metamorphism is influenced by high pressure, but pneumatolytic metamorphism is influenced by gases and chemicals.

The option B is correct.

The primary agent of contact metamorphism is heat.

Further Explanation:

Contact Metamorphism:When magma is injected towards the surrounding rock, the changes that take place are referred as Contact Metamorphism.

The greater changes take place when the magma touches rock because the temperatures roses as the distance between the boundary and the magma decreases and reaches the highest when it touches the rock or the boundary. The igneous rocks that are formed around from the cooling of the magma arereferred as a metamorphosed zone or a contact metamorphism aureole.The change that occurs is due to chemically active fluids, heat and pressure.

The ore minerals are formed by the process of metasomatism near or at the contact zone. The aureoles show different degrees of metamorphism spreading from the contact area to metamorphosed rock.Therefore,the primary agent of contact metamorphism is heat.

Therefore, the option B is correct.

For a named river you have studied, explain the causes of flooding.

Marta_Voda [28]

Answer:

Severe flooding is caused by atmospheric conditions that lead to heavy rain or the rapid melting of snow and ice. Geography can also make an area more likely to flood. For example, areas near rivers and cities are often at risk for flash floods. A flood is an overflow of water onto land that is normally dry. River flooding can happen when there is debris in the river or dams that block the flow of the water. Speaking of dams, broken dams are another cause of flooding. Older infrastructure can fail when heavy rains come and water levels rise.

How innovations in agriculture led to job specialization. how did this impact early cultures?

user100 [1]

This technique entails that community members execute various chores. Job specialization splits a community's labor into distinct tasks and allocates these jobs to various people. Job specialization results in increased competency as well as efficiency and production. As a result of the Neolithic Revolution's food surplus and population rise, job specialization developed.

The Boreal forest is a part of the alpine biome. TRUE or FALSE.

Sunny_sXe [5.5K]

The correct answer is - False.

The Boreal forest is part of the Taiga biome, not of the Alpine one. It is located on the northern hemisphere, form Norway to the Pacific coast of Russia, and from the pacific to the Atlantic coast of the northern half of North America and it occupies the biggest space compared to any other biome in the world. It is a place where there's short humid summers, and very long, extremely cold, snowy winters. It is a biome where the coniferous forest dominates, and some of the animals that live here are the lynx, bears, wolfs, elk, deer, moos...
