Back

The Moh’s scale measures the hardness of minerals.

Front

Which layer is typically the oldest in geological formations?

Back

Layer C is typically the oldest.

Front

What is a characteristic that all minerals must have?

Back

Minerals must be naturally occurring, solid under normal conditions, and have a fixed chemical composition. They do NOT have to be organic.

Front

What is a true statement about nuclear energy?

Back

Nuclear power produces radioactive waste that must be disposed of properly.

Front

What type of wind erosion was exemplified by the Dust Bowl?

Back

The Dust Bowl exemplified suspension, where sediment is lifted into the air in large clouds.

Front

Define 'mineral'.

Back

A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure.

Front

What is the difference between renewable and non-renewable energy sources?

Back

Renewable energy sources can be replenished naturally (like solar or wind), while non-renewable sources (like coal or oil) cannot be replaced once used.

Front

What is the significance of sedimentary layers in geology?

Back

Sedimentary layers provide information about the Earth's history, including past environments and life forms.

Front

Explain the term 'geosphere'.

Back

The geosphere refers to the solid parts of the Earth, including rocks, minerals, and landforms.

Front

What is erosion?

Back

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