Describe the rotation of the Earth on its axis.
The Earth rotates on its axis clockwise.
The Earth rotates on its axis counter clockwise.
The Earth does not rotate on its axis.
The Earth rotates on its axis from north to south.
Explain how the tilt of the Earth's axis affects the seasons.
The tilt of the Earth's axis causes the seasons by changing the angle at which the sun's rays strike the Earth.
The tilt of the Earth's axis has no effect on the seasons
The tilt of the Earth's axis causes the Earth to move closer to the sun, creating warmer seasons
The tilt of the Earth's axis causes the Earth to move farther from the sun, creating colder seasons

equator (North pole area
Northern Hemisphere
• Half of planet that lies below of the equator (South pole area)
Southern Hemisphere:

label
Rotation
Earth makes one rotation every day or every 24 hours
It is a complete round or spin on the axis
half of Earth’s surface faces the Sun
Imaginary horizontal line that divides the Earth into the Northern and Southern Hemisphere
Why do the lengths of the days and nights vary?
Because the axis of Earth is tilted and so does Earth
Because the hemisphere are different in sizes.
Because of the moon place
Match the following
The rotation of earth around its axis
What causes day and night to happen
The revolution of earth around the sun
What causes four seasons to happen
Earth completes one round around its axis every
24 hours
If the axis is not tilted,
day and night will be 12 hours long
has less mass and size than the. earth
moon
The gravitational force of the Moon
is smaller in size and Weaker than Earth’s
affects the Earth's water
causes tides
causes the seasons
is bigger the the earth's
As the tide comes in, the level of water on the beach
(a) , but when the tide goes out, the level (b)
There is a gravitational force between you and your desk. This gravitational force is very small because _____.
the masses are tiny compared to Earth's mass
it doesn't need to be large
the distance between the objects is small
it is a noncontact force

placement, force
force, placement
the amount of matter, gravitational force
If the mass of one of two spheres increases, how does it affect the gravity of the two spheres?
the gravity increases
the gravity decreases
the gravity fluctuates
the gravity is not affected
What force makes an apple fall to the ground?
gravity
air resistance
size
weight
If you threw a ball up on the Moon, it would go up 6 times higher than on Earth. Explain how this is possible.
The Moon has no atmosphere to slow the ball down.
The Moon's gravity is weaker than Earth's gravity.
The ball is lighter on the Moon.
The Moon's surface is smoother than Earth's.
Earth's water levels (a) on the side of Earth facing the moon.
rise
fall
_______are daily changes in ocean water.
Waters
Tides
Colors
Earths
In science class, Moza learned that he weighs 90 lb on Earth and 15 lb on the Moon. Explain why there is a difference in Moza’s weight in the two different locations.
The Moon has higher mass than Earth so its gravitational pull is much more than Earth’s. Because Moon’s gravity will pull her down strongly, Moza would weigh more on the Moon than she does on Earth
The Moon has less mass than Earth so its gravitational pull is not as strong as Earth’s. Because Moon’s gravity would not pull her down as strongly, Moza would weigh less on the Moon than he does on Earth
Moza would weigh more on the Moon than he does on Earth beacuse of the the sun
Which explains how gravity works to assist the flight of an airplane?
It pushes up on the wings of the airplane to create lift.
It helps to propel the plane forward as its speed increases.
It pushes the airplane from all directions to help it stay in the air.
It pulls the airplane downward when the pilot slows the engine's speed.
What is gravity?
The force that pulls objects together
The force that pushes objects apart
The force that pulls objects to the center of earth
Which object has more gravity?
Gravitational Pull of Earth
It is the attraction between objects and Earth
It causes every object that has mass to be pulled towards the Earth
it cause the four seasons
• Gravity
is a force of attraction, that pulls all objects in the universe
toward each other
it pulls towards earth
it pushes any object high
is a force
is a rotation
Does Location on Earth Affect Gravity?
no
yes
Which of the above masses has the greatest gravity and which one has the least? Explain
One kilo of bananas on a chair or half a kilo of apples on a chair
The bananas have greater gravity because they have greater mass but the apples have less gravity
The bananas have less gravity because they have greater mass but the apples have more gravity
The bananas have and apples have the same gravity because they are on chairs
Planet A is very large and heavy, and Planet B is much smaller and lighter. A spaceship is the same distance away from both planets. Which planet will pull on the spaceship with more gravity, and why?
Planet A will pull on the spaceship with more gravity because it has more mass. Since both planets are the same distance away, mass is the deciding factor.
Planet B will pull on the spaceship with more gravity because it has less mass. Since both planets are the same distance away, mass is the deciding factor.
Planet A and B have the same gravity because they are the same distance
The Earth revolves around the sun only and doesn't rotate around itself.
True
False
In the US, what time of day is it, according to the photo?
Day
Night
If the Earth stopped rotating but continued to revolve around the Sun, what are two major changes that would happen on Earth, and why?
One side of the Earth would always face the Sun – Without rotation, one side of Earth would always be in daylight and the other in darkness. This would cause extreme temperatures: it would get very hot on the day side and very cold on the night side.
There would be no day and night cycle – Since rotation causes day and night, without it, a single side would always have day and the other side night, meaning we wouldn’t experience sunrise or sunset anymore.
There would be no four seasons and no day and night and no life on the earth
