Question 1:

Which type of rock is formed by the solidification of molten magma?

Explanation: The type of rock that is formed by the solidification of molten magma is "Igneous rock." When magma cools and solidifies, it forms igneous rocks. Examples of igneous rocks include basalt, granite, and obsidian.

Question 2:

Which rock type is formed from the accumulation and compaction of sediments?

Explanation: The rock type that is formed from the accumulation and compaction of sediments is "Sedimentary rock." Sedimentary rocks are formed through processes such as weathering, erosion, deposition, and lithification. Examples of sedimentary rocks include sandstone, limestone, and shale.

Question 3:

Which rock type is formed by the alteration of existing rocks due to heat and pressure?

Explanation: The rock type that is formed by the alteration of existing rocks due to heat and pressure is "Metamorphic rock." Metamorphic rocks are formed when pre-existing rocks, either igneous or sedimentary, undergo changes in their mineral composition and texture. Examples of metamorphic rocks include marble, slate, and gneiss.

Question 4:

Which rock type is formed from the remains of plants and animals?

Explanation: The rock type that is formed from the remains of plants and animals is "Sedimentary rock." Sedimentary rocks often contain fossils, which are the preserved remains or traces of ancient organisms. Examples of sedimentary rocks with fossils include limestone, coal, and chalk.

Question 5:

Which rock type is formed from solidified lava?

Explanation: The rock type that is formed from solidified lava is "Igneous rock." Igneous rocks are formed from the cooling and solidification of molten material. When lava cools and solidifies above the Earth's surface, it forms volcanic or extrusive igneous rocks. Examples include basalt and pumice.
