Click on the flashcard to see the answer

What are the main layers of Earth's atmosphere?

The main layers are the Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.

What role does the Troposphere play in the atmosphere?

The Troposphere is the lowest layer and is responsible for most weather phenomena.

How does the Stratosphere differ from the Troposphere?

The Stratosphere is above the Troposphere and contains the ozone layer, with temperature increasing with altitude.

What is the significance of the Mesosphere?

The Mesosphere is where meteors burn up upon entering Earth's atmosphere.

Describe the Thermosphere and its characteristics.

The Thermosphere is characterized by high temperatures and contains the ionosphere, important for radio communication.

What happens in the Exosphere?

The Exosphere is the outermost layer where molecules escape into space.

How does temperature change with altitude in the Troposphere?

In the Troposphere, temperature typically decreases with altitude.

What is the importance of the ozone layer in the Stratosphere?

The ozone layer absorbs and scatters ultraviolet solar radiation, protecting living organisms on Earth.

How are auroras formed in the Thermosphere?

Auroras are formed by charged particles from the Sun interacting with Earth's magnetic field and ionosphere.

Why is the Exosphere considered the boundary of Earth's atmosphere?

The Exosphere merges with outer space, marking the transition between atmospheric particles and space.

Which layer of the atmosphere is crucial for weather balloons and why?

Weather balloons are often used in the Troposphere to gather atmospheric data.

What is the Kármán line and its relevance to the atmosphere?

The Kármán line is the boundary at 100 km altitude marking the beginning of space.

How do temperatures vary in the Mesosphere?

Temperatures decrease with altitude in the Mesosphere, reaching the coldest temperatures in Earth's atmosphere.

Explain the concept of atmospheric pressure and its variation with altitude.

Atmospheric pressure decreases with increasing altitude.

Which layer contains the ionosphere, and why is it important?

The ionosphere is part of the Thermosphere, essential for radio wave transmission.
