Learning Objectives: Earth's Revolution and Seasons

Define revolution. What does revolution mean in the context of planetary movement?

• Revolution is the movement of a planet around another body, such as the Earth's movement around the Sun.

• Revolution is the spinning of a planet on its own axis.

• Revolution is the process of a planet changing its shape.

• Revolution is the increase in the size of a planet over time.

Describe Earth's revolution and seasons. Explain how Earth's movement around the Sun creates our seasons.

• Earth's revolution around the Sun causes different parts of the Earth to receive varying amounts of sunlight throughout the year, resulting in the changing seasons.

• Earth's revolution around the Sun causes the length of days and nights to remain the same throughout the year, resulting in no seasonal changes.

• Earth's revolution around the Sun causes the Moon to change its phases, resulting in the changing seasons.

• Earth's revolution around the Sun causes the Earth's axis to tilt more, resulting in the changing seasons.

Identify seasonal positions. Recognise Earth's position during each season in its orbital path.

• During each season, the Earth's tilt and position in its orbit around the Sun determine the amount of sunlight different regions receive, creating spring, summer, autumn, and winter.

• The Earth's distance from the Sun is the only factor that causes the seasons, with the closest point being summer and the farthest being winter.

• Seasons are caused by the Moon's gravitational pull changing Earth's orbit throughout the year.

• The Earth's rotation speed increases and decreases, causing different seasons to occur.

Summer and winter are caused by:

• The tilt of the Earth's axis

• The distance of the Earth from the Sun

• The phases of the Moon

• The rotation of the Earth on its axis

The weather changes throughout the year because:

• the Earth orbits the Sun and its axis is tilted

• the Moon changes its phases

• the Sun moves closer and farther from the Earth

• the stars influence the weather

What is the movement of Earth around the Sun in an elliptical orbit called?

• Revolution

• Rotation

• Oscillation

• Translation

How long does it take for the Earth to complete one full revolution around the Sun?

• 365 days and 6 hours

• 24 hours

• 30 days

• 12 hours

What does the combination of Earth's revolution and its tilted axis cause?

• Four seasons

• Day and night

• Earthquakes

• Ocean tides
