Front

What is relative dating in geology?

Back

Relative dating is a method used to determine the age of rocks and fossils in relation to one another, without determining their exact age.

Front

What can relative dating indicate about fossils?

Back

Relative dating can indicate the similar time period in which different organisms lived.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

How are igneous rocks formed?

Back

Igneous rocks are formed from the cooling and solidification of molten rock (magma or lava).

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive igneous rocks form from magma that cools slowly beneath the Earth's surface, while extrusive igneous rocks form from lava that cools quickly on the surface.

Front

What is sedimentary rock?

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

Front

What are the two main types of sedimentary rocks?

Back

The two main types of sedimentary rocks are clastic (formed from fragments of other rocks) and chemical (formed from the precipitation of minerals from water).

Front

What is metamorphic rock?

Back

Metamorphic rock is formed from existing rocks that are changed by heat, pressure, or chemically active fluids.

Front

What is the rock cycle?

Back

The rock cycle is a continuous process where rocks are formed, broken down, and reformed through geological processes.

Front

What happens to sediment when a river flows into a lake?

Back

When a river flows into a lake, the velocity of the water decreases, causing larger sediments to settle first, followed by smaller sediments.
