Geology Flashcard

Front

What is weathering?

Back

The process of rocks breaking down.

Front

What type of rock is formed from the cooling and solidification of magma?

Back

Igneous rock.

Front

What is a metamorphic rock?

Back

A rock changed by heat and pressure.

Front

What are the steps in the rock cycle for a sediment to become a sedimentary rock, then magma, and finally an igneous rock?

Back

Compaction, melting, cooling.

Front

What layer of the Earth is referred to as the inner core?

Back

The innermost layer of the Earth, composed primarily of iron and nickel.

Front

What is the difference between igneous and sedimentary rocks?

Back

Igneous rocks are formed from cooled magma, while sedimentary rocks are formed from the accumulation of sediments.

Front

What is erosion?

Back

The process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water.

Front

What is the rock cycle?

Back

The continuous process of rock formation and transformation, including the formation of igneous, sedimentary, and metamorphic rocks.

Front

What is compaction in the context of sedimentary rock formation?

Back

The process by which sediments are pressed together under pressure, reducing their volume.

Front

What is melting in the rock cycle?

Back

The process by which solid rock becomes liquid magma due to high temperatures.
