5th Grade Earth Science Review

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back again, involving processes like evaporation, condensation, and precipitation.

Front

What happens during evaporation?

Back

Evaporation is the process where liquid water turns into water vapor and enters the atmosphere, usually due to heat from the sun.

Front

What is condensation in the water cycle?

Back

Condensation is the process where water vapor cools and changes back into liquid water, forming clouds.

Front

Why is Venus called the 'evening star'?

Back

Venus is often called the 'evening star' because it is one of the brightest objects in the sky after sunset, but it is actually a planet, not a star.

Front

What is a galaxy?

Back

A galaxy is a massive system that contains gas, dust, and billions of stars, all held together by gravity.

Front

What are comets made of?

Back

Comets are composed of ice, rock, and gas, and they often have a glowing coma and a tail when they come close to the sun.

Front

Where is cooler weather found in tropical climates?

Back

Cooler weather and snow in tropical climates are most likely found at the top of tall mountains due to higher altitudes.

Front

What is the difference between a planet and a star?

Back

A planet is a celestial body that orbits a star and does not produce its own light, while a star is a massive, luminous sphere of plasma that generates light and heat through nuclear fusion.

Front

What is precipitation?

Back

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

Front

What role does the sun play in the water cycle?

Back

The sun provides the energy needed for evaporation, driving the water cycle by heating water in oceans, lakes, and rivers.
