Gravity
What is gravity?
What causes seasons?
Seasons are caused by the way Earth orbits the sun on its tilted axis.
What causes day and night?
When the half of the Earth is facing the Syn it is day, when it is not facing the Sun it is night. The rotation of Earth is a complete spin on its axis. Earth makes one rotation every day. 24 hours
Define orbit
An orbit is the path one object takes around to another object.
How many times does the Earth revolve around the Sun?
Each year, the Earth makes one revolution around the Sun.
What affects the strength of gravity between two objects?
The strength of gravity between two objects is affected by the total mass of the two objects and by the distance between them.
What causes certain areas of Earth to experience different seasons?
Different parts of the Earth experience different seasons because the earth revolves around the sun which makes different temperatures. The sunlight strikes different parts of the earth at different angles.
Which movement of Earth causes day and night?
The Earths rotation on its axis is the movement which causes us to have day and night
I am the shape of a planet's orbit. Who am I?
I am an ellipse
Why do areas near the Earth's poles have long periods of darkness and daylight?
Due to the Earth's tilt. When the North Pole is tilted towards the Sun its continuously exposed to light, the North Pole is near Earths axis, it doesn't face away-long daylight. When its tilted away from the Sun then North Pole is in darkness.
What type of force is gravity?
The force of attraction and the pull of two objects
When the season in the Northern Hemisphere is Autumn, what season is it in the Southern Hemisphere?
The season would be Spring.
In what direction does Earth rotate?
Earth rotates from West to East
What has kept Earth in its path around the Sun for so long?
Gravity and Inertia
No. Each latitude of Earth would receive the same amount of sunlight and energy from the Sun all year.
What is inertia?
The tendency of a moving object to keep moving in a straight line or of any object to resist a change in motion.
What season are we in right now?
Winter
I am the spinning of Earth around its axis. I cause day and night. Who am I?
I am rotation
Which larger, the Earth or the Sun?
The Sun is much larger than the Earth
Why does the astronaut weigh less on the Moon than on Earth?
The Moon has less mass than Earth and therefore the pull of gravity is not as strong.
