Flashcard; Insolation

Front

What is insolation?

Back

Insolation is the incoming solar radiation that reaches the Earth's surface, measured in watts per square meter (W/m²). It is a key factor in determining climate and weather patterns.

Front

What angle of insolation is received at the Equator during the Equinox?

Back

The Equator receives a 90-degree angle of insolation during the Equinox.

Front

Which surface reflects the most insolation?

Back

A snow-covered field reflects the most insolation due to its high albedo.

Front

What is the duration of insolation?

Back

The duration of insolation refers to the length of time that daylight is received at a location during one day.

Front

How do greenhouse gases affect insolation?

Back

Greenhouse gases trap heat energy in the atmosphere, preventing it from escaping back into space, which contributes to the greenhouse effect.

Front

What is the albedo effect?

Back

The albedo effect is the measure of how much sunlight is reflected by a surface. Surfaces with high albedo, like ice and snow, reflect more sunlight than darker surfaces.

Front

What is the significance of the Tropic of Cancer and Tropic of Capricorn?

Back

The Tropic of Cancer and Tropic of Capricorn are the latitudes where the sun is directly overhead at noon during the summer solstices, marking the boundaries of the tropics.

Front

What factors influence the angle of insolation?

Back

The angle of insolation is influenced by the Earth's tilt, the time of year, and the latitude of the location.

Front

What is the difference between intensity of insolation and duration of insolation?

Back

Intensity of insolation refers to the strength of solar radiation received at a surface, while duration of insolation refers to the length of time that solar radiation is received.

Front

How does the Earth's atmosphere affect insolation?

Back

The Earth's atmosphere can absorb, reflect, and scatter incoming solar radiation, affecting the amount of insolation that reaches the surface.
