Day-1 Class 6 Social L-2: Earth's Four Domains Quizz

How many major domains of the Earth are students expected to identify?

• Two

• Three

• Four

• Five

Which domain of the Earth includes all water bodies such as oceans, rivers, lakes, and glaciers?

• Lithosphere

• Hydrosphere

• Biosphere

• Atmosphere

How does the lithosphere change over time?

• Through processes like erosion, volcanic activity, and continental drift

• By absorbing sunlight

• By producing rain

• Through photosynthesis

Why are tectonic plates important to the lithosphere?

• They shape Earth's surface

• They create the atmosphere

• They produce water

• They generate sunlight

How do frozen waters, such as ice caps and glaciers, contribute to Earth's systems?

• They support aquatic ecosystems

• They store freshwater and regulate climate

• They provide drinking water directly

• They form underground rivers

What are the two main gases that make up Earth's atmosphere?

• Nitrogen and oxygen

• Carbon dioxide and oxygen

• Hydrogen and helium

• Nitrogen and carbon dioxide

If the atmosphere did not exist, which of the following would most likely happen?

• Life as we know it could not exist on Earth.

• The Earth would have more oxygen.

• The weather would become more predictable.

• The sun would be cooler.

Imagine a new species is discovered living at the bottom of the ocean. Based on what you know about the biosphere, explain how this discovery supports the idea of remarkable diversity in the biosphere.

• It shows that only land animals exist

• It proves that the biosphere is limited to forests

• It demonstrates that the biosphere includes many environments and species

• It means the biosphere is shrinking

What is the process called when rain from the atmosphere falls toward Earth?

• Absorption

• Collection

• Precipitation

• Evaporation

What is the main reason the four domains of Earth interact with each other?

• To create a balanced system that supports life

• To increase the temperature of the planet

• To separate living and non-living things

• To form new continents
