Flashcard #1 - Atmosphere (REVIEW)

Front

What is the ionosphere and what occurs there?

Back

The ionosphere is a region of the thermosphere that contains charged particles. It is important for radio communication and is where auroras occur.

Front

What is the thermosphere?

Back

The thermosphere is a layer of the atmosphere where temperature increases significantly with altitude and contains the ionosphere.

Front

What is the function of the ozone layer?

Back

The ozone layer blocks harmful ultraviolet (UV) rays from reaching the Earth's surface.

Front

What layer of the atmosphere is known for weather phenomena?

Back

The troposphere is the layer of Earth's atmosphere where weather occurs.

Front

What human activity significantly contributes to increased greenhouse gases?

Back

Industrial production is a major source of increased greenhouse gases.

Front

What are the main layers of the Earth's atmosphere?

Back

The main layers of the Earth's atmosphere are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

Front

How does the temperature change in the troposphere with altitude?

Back

In the troposphere, temperature generally decreases with altitude.

Front

What is the significance of the stratosphere?

Back

The stratosphere contains the ozone layer, which protects life on Earth by absorbing UV radiation.

Front

What are auroras and where do they occur?

Back

Auroras are natural light displays predominantly seen in high-latitude regions, occurring in the ionosphere.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.
