1. what do scientists call rocks that are formed from sediments?

a. igneous rocks
b. metamorphic rocks
c. fossil rocks
d. sedimentary rocks

1. what type of rock is granite classified as?

a. metamorphic
b. sedimentary
c. igneous
d. organic

Explanation:

• Question 6: Rocks can weather and erode over time, and the resulting sediments can form soil. Rocks do not remain unchanged (they are affected by geological processes), they do not evaporate (evaporation is a process for liquids turning into gas, not applicable to rocks in this context), and they do not become ice (ice is water in solid form).
• Question 7: The rock cycle is defined as the continuous transformation of rocks from one type (igneous, sedimentary, metamorphic) to another. It is not just about destruction (a), formation from minerals (c - that's part of rock - forming but not the cycle concept), or just melting into lava (d - which is part of the cycle for igneous rock formation but not the full cycle).
• Question 8: Sedimentary rocks are formed from sediments (through processes like compaction and cementation). Igneous rocks form from magma/lava, metamorphic rocks from pre - existing rocks under heat and pressure, and “fossil rocks” is not a standard rock type classification.
• Question 9: Granite forms from the slow cooling of magma beneath the Earth's surface, which is the characteristic of igneous rock formation. Metamorphic rocks form from heat and pressure on existing rocks, sedimentary from sediments, and “organic” is not a main rock type category in this context.

Answer:

1. b. They can turn into soil
