Earth Science Cumulative Review

Front

What is an impermeable surface?

Back

An impermeable surface is a material that does not allow water or other fluids to pass through it. Examples include concrete and asphalt.

Front

What is half-life?

Back

Half-life is the time required for half of the quantity of a radioactive substance to decay. For example, the half-life of strontium-90 is 25 years.

Front

How much strontium-90 remains after 100 years if the initial amount is 4.0 g?

Back

0.25 g remains after 100 years.

Front

What element is commonly used to date fossils?

Back

Carbon-14 is commonly used to date fossils.

Front

What are the three types of evidence that support Alfred Wegener's Theory of Continental Drift?

Back

Fossils, Land forms, and Climate.

Front

What process transforms water vapor in the atmosphere to liquid water in clouds?

Back

Condensation is the process that transforms water vapor into liquid water.

Front

What is evaporation?

Back

Evaporation is the process by which liquid water turns into water vapor.

Front

What is precipitation?

Back

Precipitation is any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface, such as rain, snow, sleet, or hail.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, including processes like evaporation, condensation, and precipitation.

Front

What is the significance of fossils in Earth Science?

Back

Fossils provide evidence of past life and help scientists understand the history of the Earth and the evolution of species.
