Primary function of Earth's atmosphere in temperature regulation?

Back

Stabilizes Earth's temperature by balancing heat absorption and radiation.

Answer explanation

The Earth's atmosphere stabilizes temperature by balancing heat absorption from the sun and heat radiation back into space, preventing extreme temperature fluctuations.

Role of the greenhouse effect in Earth's climate system?

Back

Traps some outgoing infrared radiation, warming the planet.

Answer explanation

The greenhouse effect is crucial as it traps some outgoing infrared radiation, preventing it from escaping into space, which warms the planet. This process is essential for maintaining Earth's temperature and supporting life.

Sequence of atmospheric layers from Earth's surface:

Back

Troposphere, Stratosphere, Mesosphere, Thermosphere

Answer explanation

The correct sequence of atmospheric layers from the Earth's surface upwards is Troposphere, Stratosphere, Mesosphere, and Thermosphere. This order reflects how the atmosphere is structured, with the Troposphere being the lowest layer.

Wind cell between equator and 30° latitude in both hemispheres?

Back

Hadley Cell

Answer explanation

The Hadley Cell is the wind cell located between the equator and 30 degrees latitude in both hemispheres. It is responsible for the trade winds and is characterized by rising warm air at the equator and descending cool air at around 30 degrees.

Main reason for different wind cells on Earth?

Back

The rotation of the Earth

Answer explanation

The main reason for the formation of different wind cells on Earth is the rotation of the Earth. This rotation causes the Coriolis effect, which influences wind patterns and leads to the creation of distinct wind cells.

Atmospheric layer known for radio communication due to ionized particles?

Back

Thermosphere

Answer explanation

The thermosphere contains ionized particles that reflect radio waves, making it essential for radio communication. In contrast, the troposphere, stratosphere, and mesosphere do not have this property.

Primary cause of the greenhouse effect?

Back

Presence of greenhouse gases (CO2, methane)

Answer explanation

The primary cause of the greenhouse effect is the presence of greenhouse gases like carbon dioxide and methane, which trap heat in the atmosphere, leading to global warming.

Front

Consequence of the greenhouse effect?

Back

Increased global temperatures

Answer explanation

The greenhouse effect traps heat in the Earth's atmosphere, leading to increased global temperatures. This process is essential for maintaining a habitable climate, but excessive greenhouse gases can cause significant warming.
