<u>Answer:
</u>
Neither rock A nor B could become metamorphic rocks.
<u>Explanation:
</u>
- Magma is the molten rock under the surface hardens into igneous rock. This rock breaks down over time under the process of weathering.
- These pieces of "igneous rocks" are cemented together with other bits of rocks to form sedimentary rocks.
- These rocks get buried under the geological processes like earthquakes. Now, coming in contact with high temperatures and magma, these rocks get changed into metamorphic rocks.
- So, from option A, igneous rock is formed. When combined with rock B and other rocks, sedimentary rocks are formed.
- Metamorphic rocks are formed in the next process. Therefore, neither of the two rocks could become "metamorphic rocks".
The igneous layer is layers of rock formed from the cooling of magma that rises to the earth's surface and forms a vesicular texture due to gas trapped in the melt during solidification also formed as small crystal. Then the light-colored rock with a vesicular texture belongs to igneous rock, such as pumice.
What is the meaning of igneous rock?
Igneous rock can be defined as follows:
- the rock that is formed when magma rises then it experiences cooling and hardening below the earth's surface (intrusive igneous rock)
- the rock that is formed when magma rises then it experiences cooling and hardening above the earth's surface when an eruption occurs (extrusive igneous rock).
- Intrusive igneous rocks harden more slowly to form large crystals.
- Extrusive igneous rocks harden more quickly to form small crystals.
- The texture of extrusive igneous rocks is vesicular because the gas is trapped and the gas has not had time to be released because the magma hardens too quickly.
How is the process of formation of igneous rocks related to the rock cycle?
The process of formation of igneous rocks related to the rock cycle can be explained as follows:
- It starts with magma rising but does not reach the surface of the earth and remains hardened on the surface of the earth due to lower temperatures than in the magma chamber and forms intrusive igneous rocks. Meanwhile, magma that reaches the earth's surface during an eruption hardens very quickly and forms extrusive igneous rocks
- It experience weathering due to weather, hydrosphere, and biosphere factors afterwards.
- The weathering results are then dragged by the water until they reach the ocean by rivers and undergo sedimentation, namely deposition which then forms layers of sedimentary rock.
- This layer of sedimentary rock is then gradually buried deep on the earth's surface and becomes metamorphic rock
- Next, metamorphic rock deep below the earth's surface is exposed to hot temperatures
- After being exposed to hot temperatures, it returns to become magma in which the cycle will continue to rotate for a long time.
In conclusion, igneous rock is the result of magma freezing that rises to the surface of the earth and forms a vesicular texture, especially for extrusive igneous rocks. The following cycle will continue to rotate, starting from the formation of igneous rocks then turning into sedimentary rocks, metamorphic, then it melt into magma until it returns to reforming igneous rocks and so on.

Bedrock geologic map illustrating the main geologic regions of Minnesota. Igneous bodies lie across the northern half of the state, with intrusions throughout the northwest and basalts and other igneous rocks of the Duluth Complex and Beaver Bay Complex from the Midcontinent Rift System bordering Lake Superior in the northeast.
Answer:
<em><u>Eastern Africa rainfall patterns.</u></em>
Explanation:
The equator region consists of around 6% of the earth's surface involving low lands often characterised by high humidity. The dominant climate of Ethiopian highland is monsoon and the region tends cooler than other adjoining areas nearby thus different from warm tropical areas of the equator due to its height. The Rwenzori mountains support glaciers that form the Nile River, and remain snow-capped. Also called as the mountains of the moon.
Answer:
Oceans, tropical species, europe
Explanation:
- The continental drift theory put forward by the Alfred Wegner stare that the continental land got separate by the drifting of the plates that the oceans mas as they were close together in the form of a supercontinent, and are now separated by the large ocean bodies like that of the Jigsaw fit.
- The tropical species that were found in the equatorial belt s are now found in the island that is near to the place the dominance of the movement of the tectonic forces and the flight to poles explained in his theory.
- <u>The coalfields that found in North America are similar to that of the European landmass that got separated and drifts away. Thus the S shape of the atlantic oceans is characteristic of this.</u>
