What are the two most important driving forces of metamorphism?

A. High heat and pressure
B. Melting and cystallization
C. Deposition and lithification
D.Weathering and accumulation
E.Magma and lava
ne questions

Answers

Answer:

Heat and pressure

Explanation:

Metamorphic rocks are found deep underground

The two most important driving forces of metamorphism are high heat and pressure (option A).

These two factors play a significant role in transforming rocks into metamorphic rocks. When rocks are subjected to high temperatures and pressures, the minerals within them undergo changes in their composition, structure, and texture. This process leads to the formation of new minerals and the recrystallization of existing minerals, resulting in the development of distinct metamorphic textures and structures.

The course of transformation doesn't dissolve the stones, however rather changes them into denser, more conservative rocks. Rearrangements of mineral components or reactions with fluids that enter the rocks produce new minerals.

A rock sitting on the surface of the Earth is pushed down deep into the Earth over time and is exposed to tremendous heat and pressure over time. Although the rock does not melt, it does change into a new type of rock. How would the new rock be classified? Igneous Igneous Magma Magma Metamorphic Metamorphic Sedimentary

Answers

Answer:Metamorphic

Explanation:

Sedimentary rock is from sand or gravel. Igneous rock is melted rock. Metamorphic rock is rock that has been exposed to high pressure and heat but did not melt

Metamorphism refers to the change in structure and mineral composition of rocks when exposed to extreme temperatures and pressure. The correct option is metamorphic rocks.

What are metamorphic rocks?

Metamorphic rocks are one of the three types of rocks, product of subduction events, melting and transformation.

What is metamorphism?

Metamorphism provokes several changes in an original preexisting rock concerning its structure and mineral composition. The main factors causing these changes are temperature and pressure.

These physic-chemical processes usually occur in deepness and are related to plates movement and subduction processes.

The rising sharped temperature might be caused by magma injection or by a deep placement of the original rock in a subduction zone.

Pressure generates alignment of materials (foliation and schistosity) and mineral rotation

According to the metamorphism processes, there are different kinds of metamorphic rocks.

The correct option is metamorphic rocks.

A television works by transforming electrical energy into what other kinds of energy?
a) light thermal and sound
b) thermal chemical and solar
c) sound mechanical and electrical
d) light chemical and mechanical

Answers

Answer: It is A

Explanation: It is A because the television gives off light and sometimes that could heat up the tv and it is sound because obviously television makes sounds because of the volume :) hopefully that helps.

Option A, which is light heat and sound, is the right response. Electrical energy is converted into different forms of energy by a television to operate. Thermal energy, sound, and light are produced using this energy.

What is the first step of the mechanism ?

The power supply unit first changes electrical energy into alternating current (AC). The image tube, which has a vacuum and an electron gun, receives this AC after that. Electrical energy is transformed into thermal and optical energy by the electron cannon.

The thermal energy is subsequently lost while the light energy is focused onto the screen. The speakers produce the sound by transforming electrical energy into sound waves. The other choices are inaccurate because they do not adequately depict how a television converts energy.

Option B uses energy sources other than televisions, such as chemical and solar energy. The mechanical and electrical energy found in the television is included in Option C. Option D also uses chemical and mechanical energy, which a television cannot produce.

As a result, choice A is the right response.

Antimycin A Antimycin A is used in catfish farming: added to the water at 10 ppb, it kills small fish but does not harm catfish. Thus, small fish die out, and catfish get all the resources. When Antimycin A is added to isolated mitochondria, NADH and succinate both accumulate. However, if ascorbate, an artificial redox mediator that transfers electrons to cytochrome c, is added, oxygen consumption is still observed. Which step in the respiratory chain is antimycin A likely to inhibit (1 pt)

Answers

Answer:

Inhibits electron transport chain in mitochondria.

Explanation:

Antimycin A inhibits electron transport chain which leads to the complete halt of electron transport in mitochondria. due to this inhibition of electron transport chain in mitochondria leads to the killing of the fishes except catfish and so the catfish increase in population due to more resources and no competition. this Antimycin A is highly toxic for fishes and kill all fishes if used at the amount of 10 ppb.
