Grade 5 Science Review 1

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, involving processes like evaporation, condensation, and precipitation.

Front

What causes liquid water to change into water vapor?

Back

Heat from the sun causes liquid water to evaporate and change into water vapor.

Front

What is an orbit?

Back

An orbit is the path that an object takes as it moves around another object in space, such as the Earth orbiting the Sun.

Front

What are galaxies primarily made of?

Back

Galaxies are primarily made of stars, gas, dust, and dark matter.

Front

What is the role of gravity in space?

Back

Gravity is the force that pulls objects toward each other, keeping planets in orbit around stars and moons in orbit around planets.

Front

What happens to water vapor when it meets cooler air?

Back

When water vapor meets cooler air, it condenses into droplets of liquid water, forming clouds.

Front

What is energy?

Back

Energy is the ability to do work or cause change, and it can exist in various forms such as kinetic, potential, thermal, and more.

Front

How does a ramp help in moving objects?

Back

A ramp allows objects to move from a lower height to a higher height using gravitational potential energy, making it easier to roll or slide objects.

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 celestial body that generates light and heat through nuclear fusion.

Front

What is condensation in the water cycle?

Back

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