Earth's Movements (Seasons, Day/Night)

Earth's Movements

Lesson Goal: ​SWBAT describe and model how the movement of the Earth causes seasons and day and night.

Seasons

• Tilted Axis + Orbit Around Sun = Seasons

• Tilt of axis never changes, always points in the same direction

• Areas tilted toward the sun get more sunlight and heat (summer)

• Areas tilted away from the sun get less sunlight and heat (winter)

Multiple Choice

Why do seasons occur?

• Due to Earth’s revolution and the tilt of our planet

• Due to Earth’s rotation and the tilt of our planet

• Due to Earth’s revolution only

Multiple Choice

Rotation of the Earth causes..

• Convection in the mantle

• Seasons

• Day/Night

• Hurricanes

Multiple Choice

How long does it take for the Earth to make one full orbit around the Sun?

• one day

• one week

• one month

• one year

Poll

What is the reason for warm weather during the summer in the northern hemisphere?

• The Earth is closer to the Sun in the summer.

• The Northern Hemisphere is closer to the Sun in the summer.

• The Sun gives off more heat in the summer than in the winter.

• The North pole is tilted toward the Sun during the summer.

When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere.

​

This is because the Northern Hemisphere is receiving more direct sunlight.

Summer in the Northern Hemisphere

The Southern Hemisphere is receiving more direct sunlight than the Northern Hemisphere.

Winter in the Northern Hemisphere

Fall and Spring Equinoxes

• Both hemispheres receive the same amount of direct sunlight.

• Both hemispheres have equal day and night (12 hours of day, 12 hours of night).

• Neither hemisphere is tilted toward/away from the sun at this time.

• Neither hemisphere is very warm or cold.

Multiple Choice

The days of the year where Earth experiences equal amounts of sunlight and darkness.

• Equinoxes

• Solstices

• Darquinoxes

Match

Match the Season in the Northern Hemisphere that corresponds to the Season that occurs in Southern Hemisphere

• Summer in Northern Hemisphere

• Fall/Autumn in Northern Hemisphere

• Winter in Northern Hemisphere

• Spring in Northern Hemisphere

Winter in Southern Hemisphere

Spring in Southern Hemisphere

Summer in Southern Hemisphere

Fall/Autumn in Southern Hemisphere

• Winter in Southern Hemisphere

• Spring in Southern Hemisphere

• Summer in Southern Hemisphere

• Fall/Autumn in Southern Hemisphere

Multiple Choice

Which season(s) have the same amount of daylight hours as nighttime hours?

• Winter & Summer

• Spring & Fall

• Spring & Summer

• They are all equal

• revolution

• rotation

• precession

• orbit

Multiple Choice

The movement of the Earth around the Sun is called its _____

• revolution

• rotation

• precession

• retrograde

The North Star

• Polaris, the North Star, sits quite near the celestial north pole

• Polaris was not always the North Star and will eventually be replaced as the stars move across the sky

Multiple Choice

In what direction does the Sun appear to move across the sky?

• West to east

• North to south

• East to west

• South to north

Multiple Choice

Which of these cycles is a direct result of Earth's ROTATION

• Day and Night

• Moon Phases

• Convection in the Mantle

• Seasons

Multiple Choice

Which of these best explains why the sun appears to move across the sky each day?

Multiple Choice

A student draws a model showing the movements on Earth, the moon, and the sun. Which arrow shows the movement that caused day and night on Earth?

• Arrow 1, because it shows the rotation of the sun

• Arrow 2, because it shows the orbit of Earth around the sun

• Arrow 3, because it shows the orbit of the moon around Earth

• Arrow 4, because it shows the rotation of the Earth

Multiple Choice

The Night happens because one side of the Earth is facing away from the Sun.

• True

• False

Multiple Choice

The Sun rises in the ____ and sets in the ____.

• West, East

• North, South

• East, West

• Sputh, North

Multiple Choice
