What is the process by which rocks are broken down into smaller pieces by natural forces like wind and rain?
Back
Weathering

FLASHCARD QUESTION
Front
What type of rock is formed as a result of the cementation of layers of sediments?
Back
Sedimentary
Answer explanation
Sedimentary rocks are formed through the cementation of layers of sediments over time. This process involves the compaction and binding of particles, distinguishing them from igneous and metamorphic rocks.

FLASHCARD QUESTION
Front
Which process is crucial in the formation of igneous and metamorphic rocks through the formation of crystals?
Back
Crystallization
Answer explanation
Crystallization is the key process in forming igneous and metamorphic rocks, as it involves the cooling and solidification of molten material, leading to the growth of crystals. This distinguishes it from erosion, compaction, and weathering.

What is the term for rocks that are formed when existing rocks are transformed by heat or pressure?
Back
Metamorphic
Answer explanation
Rocks formed by the transformation of existing rocks through heat or pressure are called metamorphic rocks. This distinguishes them from sedimentary rocks, which form from sediment, and igneous rocks, which form from molten material.
