What are sedimentary rocks?

Back

Sedimentary rocks are types of rocks formed by the accumulation and compaction of mineral and organic particles over time.

Front

What is compaction in geology?

Back

Compaction is the process by which sediments are pressed together under pressure, leading to the formation of sedimentary rocks.

Front

What is the relationship between mass and force?

Back

The relationship is described by Newton's second law, which states that force equals mass times acceleration (F=ma). More mass requires more force to move.

Front

What factors can change the size and shape of a delta?

Back

Factors include the amount and size of sediments carried by rivers, tides, and ocean waves, but not hunting and fishing.

What types of energy does a toy oven use?

Back

A toy oven uses electrical energy to power it and thermal energy to bake the cakes.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter; it is the total energy of all the particles in an object.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor.

Front

What is a delta?

Back

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

Front

What is the role of tides in shaping coastal landforms?

Back

Tides can erode and deposit sediments along the shore, affecting the shape and size of coastal landforms.
