One of the main jobs of the roots is to keep the plants in the soil, not to be swept away by heavy rain, these roots help keep the soil in its place. Some areas do not have plants, in these areas, soil is carried away by the heavy rain. Which sentence in this passage shows interaction between the hydrosphere and the geosphere?

• Roots help keep the soil in its place

• Roots help keep the plants in its place

• Soil is carried away by the heavy rain

• Some areas do not have plants

All living things on Earth make up the:

• Biosphere

• Atmosphere

• Geosphere

• Hydrosphere

Water that soaks into the ground through cracks is known as:

• Runoff water

• Groundwater

• Glacier

• Icecap

Water in the atmosphere is known as:

• Glacier

• Ice

• Solid water

• Water vapor

While making food, plants use __________ gas from the air and give out _____ that other living things need.

• Oxygen, water vapor

• Sugars, oxygen

• Carbon dioxide, Nitrogen

• Carbon dioxide, oxygen

Both plants and animals require oxygen gas to use the energy stored in food. They breathe in oxygen that helps in breaking down food to release the energy with a waste material, carbon dioxide gas, that they breathe out. Carbon dioxide gas is also needed by plants to make food by the process called photosynthesis. During photosynthesis, plants give off oxygen gas that is returned to the atmosphere. This scenario best describes the __________ cycle.

• Water

• Oxygen-carbon dioxide

• Nitrogen

• Hydrogen

Water in the ocean heats up by the Sun and turns into gas. This process is called:

• Condensation

• Evaporation

• Precipitation

• Transpiration
