Science 8 INSOLATION/SEASONS

Front

What is insolation?

Back

Insolation refers to the amount of solar radiation received by a given area, typically measured in watts per square meter.

Front

How does the angle of sunlight affect insolation?

Back

The angle of sunlight affects insolation because sunlight hitting the Earth at a steeper angle (closer to 90 degrees) is more concentrated and therefore more intense than sunlight hitting at a shallower angle.

Front

What season occurs in the Northern Hemisphere when the Sun is at its highest point in the sky?

Back

Summer occurs in the Northern Hemisphere when the Sun is at its highest point in the sky.

Front

What happens to the length of shadows as the angle of the Sun decreases?

Back

As the angle of the Sun decreases, the length of shadows increases.

Front

What is the relationship between the angle of sunlight and the intensity of light received?

Back

The intensity of light received increases as the angle of sunlight approaches 90 degrees and decreases as the angle moves away from 90 degrees.

Front

What season begins in the Northern Hemisphere when summer ends?

Back

Fall begins in the Northern Hemisphere when summer ends.

Front

At what angle does the dot receive the least intense amount of light?

Back

The dot receives the least intense amount of light at an angle of 30 degrees.

Front

What effect does angling a flashlight closer to a surface have on the size of the light circle?

Back

Angling a flashlight closer to a surface increases the size of the circle of light.

Front

What is the significance of the Earth's tilt in relation to seasons?

Back

The Earth's tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the changing seasons.

Front

What is the primary cause of seasonal changes on Earth?

Back

The primary cause of seasonal changes on Earth is the tilt of the Earth's axis and its orbit around the Sun.
