Copy*1st Semester Science Test

Front

What is the driving force of ocean currents and atmospheric movement?

Back

Unequal heating of Earth by the Sun.

Front

What is denitrification?

Back

The process where bacteria transform nitrogen compounds in the soil into nitrogen gas that is released into the air.

Front

What happens to water in a covered cup versus an uncovered cup over time?

Back

The amount of water in the covered cup will remain the same, while the uncovered cup will lose water due to evaporation.

Front

What can organisms that are buried without decomposing transform into over millions of years?

Back

Fossil fuels.

Front

What process do animals undergo when they break down organic molecules?

Back

Animals are breaking down organic molecules and releasing carbon dioxide into the atmosphere.

Front

What is the water cycle?

Back

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

Front

What is evaporation?

Back

The process by which water changes from a liquid to a gas, usually due to heat.

Front

What is condensation?

Back

The process by which water vapor in the air is changed into liquid water, often forming clouds.

Front

What are fossil fuels?

Back

Natural substances formed from the remains of ancient organisms, used as energy sources, such as coal, oil, and natural gas.

Front

What is the role of the Sun in the water cycle?

Back

The Sun provides the energy needed for evaporation, driving the water cycle.
