Fossils & Weathering/Erosion

Front

What are fossils?

Back

Fossils are the preserved remains or traces of animals, plants, and other organisms from the past.

Front

Where are fossils most commonly found?

Back

Fossils are most commonly found in sedimentary rock, especially near bodies of water.

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through natural forces like wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by water, wind, or ice.

Front

What is sedimentary rock?

Back

Sedimentary rock is a type of rock formed by the accumulation of sediments, which can include minerals, organic matter, and other materials.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation, breakdown, and reformation, involving igneous, sedimentary, and metamorphic rocks.

Front

What causes the greatest erosion effect on beaches?

Back

Waves cause the greatest erosion effect on beaches by constantly crashing against the shore and moving sand and sediment.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken materials to a different location.

Front

What is the youngest layer of rock in a sedimentary sequence?

Back

The youngest layer of rock is typically found at the top of a sedimentary sequence.

How do fossils help scientists?

Back

Fossils help scientists understand the history of life on Earth, including how organisms evolved and how environments changed.
