5th grade Earth's Surface and Rock Formation Flashcard

Front

What are sedimentary rocks?

Back

Sedimentary rocks are types of rocks formed by the accumulation and compaction of mineral and organic particles, often found in layers.

Front

What is the process of compaction in rock formation?

Back

Compaction is the process where sediments are pressed together under pressure, reducing their volume and leading to the formation of sedimentary rocks.

Front

What is cementation in the context of sedimentary rocks?

Back

Cementation is the process where dissolved minerals crystallize and bind sediment particles together, forming solid rock.

Front

How do glaciers affect the Earth's surface?

Back

Glaciers can erode land by scraping away soil and rock, and they can also deposit sediments as they melt.

Front

What is a delta?

Back

A delta is a landform created by the deposition of sediment at the mouth of a river, where the river meets a body of water.

Front

How does wind contribute to the formation of sand dunes?

Back

Wind erodes sand from one area and deposits it in another, creating sand dunes over time.

Front

What is the role of vegetation in coal formation?

Back

Vegetation can become buried quickly in certain environments, and over millions of years, heat and pressure can transform it into coal.

Front

What are the main factors that lead to sedimentary rock formation?

Back

The main factors are compaction and cementation of sediments.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural forces such as wind, water, and ice.

Front

What is deposition in geology?

Back

Deposition is the process where sediments are laid down in new locations after being transported by wind, water, or ice.
