The primary agent of contact metamorphism is a. flowing water
b. heat
c.extreme pressure
d. weathering

Answers

Answer 1

Answer:

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.

Answer 2

Answer:

The primary agent of contact metamorphism is:

(B) Heat

Further explanation

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.

What happens if the use of groundwater exceeds the rate of replenishment?a. the depth of the water table increases
b. the water table is more likely to be polluted
c. the depth of the water table decreases
d. the water table remains unchanged

Answers

The answer is C. the depth of the water table decreases

Water table is the boundary between water-saturated ground and unsaturated ground.

When the groundwater dissapear faster than it replenish, the depth will decreases, making it harder for people to gain access to the groundwater

The answer is C. the depth of the water table decreases

Yes, this is true

Hope my answer would be a great help for you. If you have more questions feel free to ask here at Brainly.

Final answer:

The layers of the sun, ranked from greatest to least distance from the sun's center, are: core, radiative zone, convective zone, photosphere, chromosphere, transition region, and corona.

Explanation:

Core: The sun's core is the innermost layer and the hottest part of the sun. It is where nuclear fusion occurs, producing the sun's energy.
Radiative Zone: Surrounding the core is the radiative zone, where energy from the core is transported through radiation.
Convective Zone: Next is the convective zone, where energy is transported through convection, as hot plasma rises and cool plasma sinks.
Photosphere: Above the convective zone is the photosphere, the visible surface of the sun. It has a temperature ranging from 4500 K to about 6800 K.
Chromosphere: Above the photosphere is the chromosphere, which has a typical temperature of 104 K.
Transition Region: A thin zone called the transition region has a rapid increase in temperature from 104 K to 106 K.
Corona: Finally, the outermost layer is the corona, with temperatures reaching a few million K.

How are surface ocean currents formed?

Answers

Winds are able to move the top 400 meters of the ocean creating surface ocean currents. Surface ocean currents form large circular patterns called gyres. Gyres flow clockwise in Northern Hemisphere oceans and counterclockwise in Southern Hemisphere oceans because of the Coriolis Effect.
