Chapter 3 - Earths Tilt

Define Heliocentric?

• The Sun is the center of the solar system

• Half of the Earth

• A flat 2-dimensional surface

• The line the Earth rotates around

Define Hemisphere?

• Half of the Earth (Correct)

• The Sun is the center of the solar system

• A flat 2-dimensional surface

• The line the Earth rotates around

Define plane?

• A flat 2-dimensional surface

• The Sun is the center of the solar system

• Half of the Earth

• The line the Earth rotates around

What is the main reason for Earth’s seasons?

• The tilt of Earth’s axis

• Earth’s distance from the Sun

• The shape of Earth’s orbit

• The speed of Earth’s rotation

During the Northern Hemisphere’s winter, what is happening in the Southern Hemisphere?

• It is summer.

• It is spring.

• It is autumn.

• It is winter.

Why does the equator experience consistent weather year-round?

• The angle of the Sun’s rays remains constant.

• The equator is closer to the Sun.

• The equator is tilted away from the Sun.

• The equator has a different atmosphere.

Why is the Northern Hemisphere colder in December than in June, despite Earth being closer to the Sun in December?

• Because the Northern Hemisphere tilts away from the Sun in December

• Because the Sun’s energy is less intense

• Because the Earth’s axis is not tilted in June

• Because the days are shorter in June

What would likely happen if Earth did not rotate or tilt but still revolved around the Sun?

• Seasons would not occur

• Earth would be colder

• Days would be much longer

• There would be no day or night

Why do the poles experience 24 hours of daylight or darkness during certain months?

• Due to Earth’s tilt on its axis

• Due to Earth’s distance from the Sun

• Due to reduced solar energy

• Due to the shape of Earth’s orbit

Why do people near the equator not experience typical 4 seasons?

• Because the angle of the Sun’s rays is always the same

• Because the Sun is closer to the equator

• Because the equator is tilted more than other areas

• Because the equator receives less sunlight
