Atmosphere: Energy Distribution

Question 1

Curvature of the Earth: Sun’s rays are more concentrated in smaller area in the tropics- what does this result in?

Answer 1

Due to the curvature of the earth in the tropics the sun’s rays are concentrated on a smaller area resulting in a more intense heat.

Question 2

Curvature of the Earth: Less atmosphere to pass through at the tropics so…

Answer 2

Rays have less atmosphere to pass through at the tropics so less energy is lost through absorption and reflection

Question 3

Albedo Effect: How do darker and lighter surfaces differ in how they receive light? (absorb and reflect)

Answer 3

Darker forests at the tropics absorbed more energy and lighter surfaces at the poles reflect more energy.

Question 3

Albedo Effect: What is the Albedo Effect?

Answer 3

The albedo effect is the reflectiveness of the Earth’s surface.

Question 4

The Earth’s Tilt: How does insolation differ between the poles and tropics? (Amount during the year)

Answer 4

Due to the tilt of the Earth, limited insolation is received at the Poles in winter, whereas tropical areas receive insolation all year round
