Layers and Spheres

What is the biosphere?

• The biosphere is the global sum of all ecosystems on Earth, including all living organisms and the physical environment in which they live.

• The biosphere is the process of converting sunlight into energy in plants

• The biosphere is the study of ancient life forms through fossils

• The biosphere is the layer of the atmosphere that protects Earth from UV radiation

Which layer of the atmosphere is closest to the Earth's surface?

• Troposphere

• Exosphere

• Mesosphere

• Stratosphere

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

• Approximately 30%

• Approximately 50%

• Approximately 90%

• Approximately 71%

What is the primary gas in the Earth's atmosphere?

• Oxygen

• Helium

• Carbon dioxide

• nitrogen.

What is the role of the biosphere in the Earth's ecosystem?

• The biosphere only affects the atmosphere

• The biosphere only interacts with the lithosphere

• The biosphere has no role in the Earth's ecosystem

• supporting and regulating life through the interaction of living organisms with the atmosphere, hydrosphere, and lithosphere.

What are the different layers of the atmosphere, starting from the Earth's surface?

• The different layers of the atmosphere are the stratosphere, ionosphere, and oceanosphere.

• The different layers of the atmosphere are the oceanosphere, lithosphere, and biosphere.

• The different layers of the atmosphere are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

• The different layers of the atmosphere are the ionosphere, exosphere, and lithosphere.

How does the hydrosphere impact the climate of the Earth?

• The hydrosphere has no impact on the climate of the Earth

• The hydrosphere impacts the climate of the Earth through volcanic eruptions

• The hydrosphere impacts the climate of the Earth through solar radiation

• The hydrosphere impacts the climate of the Earth through evaporation, precipitation, and the regulation of temperature through bodies of water.

What are the different components of the atmosphere?

• Methane, ammonia, ozone, water vapor, and sulfur dioxide

• Hydrogen, sulfur, radon, helium, and neon

• nitrogen, oxygen, argon, carbon dioxide, and trace gases.

• Water, helium, neon, krypton, and xenon

How do human activities impact the biosphere?

• Human activities impact the biosphere through processes such as deforestation, pollution, and habitat destruction.

• Human activities have no impact on the biosphere.

• Human activities impact the biosphere through mind control.

• Human activities impact the biosphere through time travel.

What are the major sources of pollution in the atmosphere?

• industrial emissions, vehicle exhaust, and agricultural activities.

• Bird migration patterns

• Ocean waves and tides

• Burning candles and incense
