What does the hydrosphere include?

All of Earth’s water.

100

What is the geosphere made of?

Rocks, soil, and Earth’s landforms.

100

What is the atmosphere?

The layers of gases surrounding Earth.

100

What is the biosphere?

All living things on Earth.

100

What two spheres interact when a plant uses sunlight, water, and soil to grow?

Biosphere, hydrosphere, and geosphere (plus atmosphere if sunlight is mentioned).

200

Name the largest part of Earth’s hydrosphere.

The oceans.

200

Give one example of a landform in the geosphere.

Mountains, valleys, plains, or plateaus.

200

Name one gas found in the atmosphere.

Oxygen, nitrogen, or carbon dioxide.

200

Give an example of an organism in the biosphere.

Plants, animals, humans, bacteria, fungi.

200

What two spheres interact when a volcano erupts?

Geosphere and atmosphere (plus biosphere if life is affected).

300

True or False: Ice and glaciers are part of the hydrosphere.

True.

300

What sphere does soil belong to?

Geosphere.

300

What does the atmosphere do for life on Earth?

Provides air to breathe, protects us from the Sun’s harmful rays, and regulates temperature.

300

How does the biosphere depend on the hydrosphere?

Living things need water to survive.

300

What two spheres interact when humans cut down a forest?

Biosphere and geosphere (plus atmosphere if carbon dioxide levels are mentioned).

400

What process moves water from the hydrosphere into the atmosphere?

Evaporation.

400

Name a process in the geosphere that changes Earth’s surface.

Erosion, weathering, earthquakes, or volcanoes.

400

What process moves water from the atmosphere back to the hydrosphere?

Precipitation (rain, snow, sleet, hail).

400

How does the biosphere depend on the geosphere?

Plants grow in soil; animals make homes in the ground.

400

How does the hydrosphere affect the atmosphere during the water cycle?

Water evaporates from oceans and lakes into the air.

500

Why is the hydrosphere important for living things?

It provides fresh water for drinking, food sources, and habitats.

500

How does the geosphere interact with the hydrosphere?

Rain (hydrosphere) erodes rocks and shapes landforms (geosphere).

500

How does the atmosphere affect the biosphere?

It provides oxygen and carbon dioxide for living things and weather that affects habitats.

500

How does the biosphere depend on the atmosphere?

Living things need oxygen and carbon dioxide to survive.

500

Give an example of all four spheres interacting.

A hurricane: Water (hydrosphere) moves through air (atmosphere), floods the land (geosphere), and impacts humans and animals (biosphere).
