What is the primary function of the exosphere in Earth's atmosphere?

• Protects Earth from meteoroids

• Facilitates satellite communication

• Regulates Earth's temperature

• Supports life by providing oxygen

Which layer of Earth's atmosphere is directly below the exosphere?

• Troposphere

• Stratosphere

• Mesosphere

• Thermosphere
