Earth's Spheres and Resources Quiz

What are the five major spheres of the Earth mentioned in the text?

• Atmosphere, Hydrosphere, Cryosphere, Geosphere, Biosphere

• Atmosphere, Lithosphere, Stratosphere, Mesosphere, Exosphere

• Hydrosphere, Lithosphere, Troposphere, Thermosphere, Biosphere

• Geosphere, Lithosphere, Atmosphere, Exosphere, Cryosphere

Answer explanation

The correct answer is 'Atmosphere, Hydrosphere, Cryosphere, Geosphere, Biosphere' as these are the five major spheres of the Earth, encompassing air, water, ice, land, and life.

Which sphere is responsible for providing oxygen to breathe and carbon dioxide for photosynthesis?

• Hydrosphere

• Geosphere

• Atmosphere

• Cryosphere

Answer explanation

The atmosphere is the layer of gases surrounding Earth, providing oxygen for breathing and carbon dioxide for photosynthesis, making it essential for life and plant growth.

Which scientists study the atmosphere?

• Geologists

• Meteorologists, climatologists, and atmospheric scientists

• Biologists and botanists

• Oceanographers and marine biologists

Answer explanation

Meteorologists, climatologists, and atmospheric scientists specifically study the atmosphere, focusing on weather patterns, climate change, and atmospheric phenomena, unlike the other scientists listed.

What is the main function of the cryosphere?

• Producing oxygen

• Regulating Earth's temperature and storing freshwater

• Providing soil and minerals

• Supporting plant life

Answer explanation

The cryosphere plays a crucial role in regulating Earth's temperature by reflecting sunlight and storing freshwater in the form of ice and snow, which is vital for ecosystems and human use.

Which sphere includes rocks, soil, and minerals?

• Biosphere

• Hydrosphere

• Geosphere

• Cryosphere

Answer explanation

The geosphere includes all the solid parts of the Earth, such as rocks, soil, and minerals. In contrast, the biosphere relates to living organisms, the hydrosphere to water, and the cryosphere to ice.

What are examples of nonrenewable resources found in the geosphere?

• Water and air

• Coal, sand, and metal ores

• Plants and animals

• Glaciers and ice caps

Answer explanation

Nonrenewable resources are those that cannot be replenished in a short time. Coal, sand, and metal ores are extracted from the geosphere and take millions of years to form, making them nonrenewable. Water, air, plants, and animals are renewable.

Who studies the biosphere?

• Meteorologists

• Oceanographers

• Biologists, botanists, and ecologists

• Glaciologists

Answer explanation

The biosphere is studied by biologists, botanists, and ecologists, as they focus on living organisms and their interactions with the environment. Meteorologists, oceanographers, and glaciologists study different aspects of Earth.

What does the biosphere include?

• Only plants

• Only animals

• All living things—plants, animals, and people

• Only microorganisms

Answer explanation

The biosphere encompasses all living things on Earth, including plants, animals, and humans. Therefore, the correct answer is 'All living things—plants, animals, and people', as it accurately reflects the diversity of life in the biosphere.

Which of the following is a renewable resource if used wisely?

• Coal

• Sand

• Water

• Metal ores

Answer explanation

Water is a renewable resource because it can be replenished through the natural water cycle. When used wisely, such as through conservation and sustainable management, it can be continuously available, unlike coal, sand, or metal ores.
