Spheres of the Earth

What is the atmosphere?

• The layer of gases that surrounds the Earth

• The layer of solid rock that makes up the Earth's surface

• The layer of ice covering the Earth

• The layer of molten lava beneath the Earth's crust

Name one gas that makes up the Earth's atmosphere.

• oxygen

• carbon dioxide

• helium

• nitrogen

What percentage of the Earth's surface is covered by water?

• 30%

• 90%

• 71%

• 50%

What is the biosphere?

• The biosphere is a man-made structure for growing plants

• The biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, hydrosphere, and atmosphere.

• The biosphere is a type of telescope used to study outer space

• The biosphere is a musical instrument made from natural materials

Give an example of an interaction between the hydrosphere and the geosphere.

• Tectonic plate movement causing earthquakes

• Volcano erupting under the ocean

• Rainfall causing erosion on a mountain

• River carving through rock to form a canyon

What is the geosphere?

• The layer of gases surrounding the Earth

• The liquid part of the Earth, including the oceans and seas

• The solid part of the Earth, including the rocks, minerals, and landforms

• The layer of ice and snow covering the Earth

How do living organisms interact with the atmosphere?

• Through communication with extraterrestrial beings

• Through processes such as respiration, photosynthesis, and the carbon cycle.

• By absorbing sunlight directly through their skin

• By controlling the weather

Explain the concept of the water cycle and its relation to the hydrosphere.

• The water cycle is the movement of air on, above, and below the surface of the Earth, and it is related to the hydrosphere as it involves the storage of air in the Earth's atmosphere.

• The water cycle is the continuous movement of rocks on, above, and below the surface of the Earth, and it is related to the hydrosphere as it involves the movement and storage of rocks in the Earth's water bodies.

• The water cycle is the continuous movement of fire on, above, and below the surface of the Earth, and it is related to the hydrosphere as it involves the movement and storage of fire in the Earth's water bodies.

• The water cycle is the continuous movement of water on, above, and below the surface of the Earth, and it is related to the hydrosphere as it involves the movement and storage of water in the Earth's water bodies.

Describe the impact of human activities on the Earth's spheres.

• Human activities only have a positive impact on the Earth's spheres

• Human activities can lead to air and water pollution, deforestation, habitat destruction, and climate change.

• The impact of human activities on the Earth's spheres is minimal

• Human activities have no impact on the Earth's spheres
