What is the primary reason for the Earth experiencing different seasons?

• The Earth's distance from the sun.

• The Earth's tilted axis.

• The Earth's rotation on its axis.

• The moon's gravitational pull.

If it is summertime in the Northern Hemisphere, what season is the Southern Hemisphere experiencing?

• Spring

• Summer

• Autumn

• Winter

In the solar panel experiment, when the Earth model is tilted towards the light source, what happens to the motor in the hemisphere receiving more direct light?

• It slows down significantly.

• It stops completely.

• It spins faster.

• It spins at the same speed as the other motor.

Why is summer generally hotter than winter?

• The Earth is closer to the sun in summer.

• The sun's rays hit the Earth more directly in summer.

• There are more clouds in winter, blocking sunlight.

• The Earth's atmosphere is thicker in summer.

Sort the following.

Groups:

What phenomenon demonstrates that the Earth is constantly spinning?

• The changing phases of the moon.

• The movement of ocean tides.

• The apparent movement of stars across the night sky.

• The consistent change in the swing direction of a Foucault's Pendulum.

What is the primary reason for the Earth experiencing different seasons throughout the year?

• The Earth's varying distance from the Sun during its orbit.

• The Earth's axis being tilted relative to its orbital plane.

• Changes in the Sun's energy output.

• The Moon's gravitational pull on the Earth.

When the Northern Hemisphere is experiencing summer, what season is typically occurring in the Southern Hemisphere?

• Spring

• Summer

• Autumn

• Winter

Why does direct sunlight cause warmer temperatures compared to sunlight hitting at an angle?

• Direct rays travel a shorter distance through the atmosphere.

• Direct rays are concentrated over a smaller area.

• Angled rays are reflected more by the Earth's surface.

• Angled rays contain less energy from the Sun.
