Science Test Tuesday!

Question 1

Heliocentric

Answer 1

Sun at the center of the solar system

Question 2

Geocentric

Answer 2

Earth at the center of the solar system

Question 3

Which way does the earth rotate

Answer 3

West to east

Question 4

How long does it take to rotate once around

Answer 4

It takes 24 hours to rotate once around. This determines the length of our day.

Question 5

How many time zones

Answer 5

There are 24 major time zones on Earth.

Question 6

does the distance from the sun determine the season?

Answer 6

No

Question 7

What determines the seasons

Answer 7

As the Earth moves around the sun, the position of its tilt in relation to the sun determines the season.

Question 8

solstice

Answer 8

one day per year when the sun is at its highest point in the sky. It occurs when either the Northern or the Southern Hemisphere is at its strongest tilt towards the sun.

Question 9

Equinox

Answer 9

halfway between solstices, neither hemisphere is tilted towards the sun. This day occurs when the sun passes directly over the equator at noon and night and day are both 12 hours long. Equinox means “equal night”.

Question 10

Newtons first law

Answer 10

The Law of Inertia is Newton’s first law of motion

Question 11

What does inertia do?

Answer 11

Inertia keeps the Earth on its orbit and prevents it from crashing into the sun

Question 12

Gravity

Answer 12

a force that attracts all objects toward each other.

Question 13

Inertia and gravity

Answer 13

Gravity and Inertia work together to keep the Earth in its orbit.

Question 14

What does gravity do?

Answer 14

Gravity keeps the Earth in orbit around the sun.

Question 15

Phases of the moon

Answer 15

I know these stupid

Question 16

Earths orbit

Answer 16

an object at rest will remain at rest, and an object in motion will remain in motion unless acted upon by an unbalanced force.

Question 17

How does the moon rotate about the earth?? idk

Answer 17

The moon rotates once on its axis in the same time it takes to revolve around the Earth

Question 18

How does the view from space affect the moon

Answer 18

The view from space shows the moon as always being half lit by the sun.

Question 19

what faze does the moon have to be in for there to be a lunar eclipes

Answer 19

Full moon

Question 20

What is a total lunar eclipse

Answer 20

total lunar eclipse- the moon is completely within the umbra of the Earth’s shadow.

Question 21

WHat is a partial luner eclipes

Answer 21

Partial lunar eclipse- the moon is within the penumbra.

Question 22

Why is the moon red

Answer 22

Blue light is scattered by the Earth’s atmosphere. Red light gets refracted, passes through the atmosphere and falls onto the Moon.

Question 23

What faze does the moon have to be in to have a solar eclipse

Answer 23

New moon

Question 24

When does the solar eclipse occur

Answer 24

The solar eclipse occurs when the moon passes directly between the Earth and the sun, blocking the sun’s light from reaching a small area on the Earth.

Question 25

When do you see a total solar eclipse

Answer 25

To see the total eclipse of the sun you need to be in the umbra of the moon’s shadow (very small area compared to the lunar eclipse)

Question 26

How do you see a partial solar eclipse

Answer 26

To see a partial eclipse of the sun, you need to be within the penumbra of the moon’s shadow.

Question 27

Orbit

Answer 27

the path that the Earth takes as it revolves around the sun. This path is an ellipse, an oval shape.

Question 28

Star

Answer 28

a giant ball of superheated gas, or plasma, composed of hydrogen and helium.

Question 29

Planet

Answer 29

an object that orbits the sun, is large enough to have become rounded by its own gravity and has cleared the area of its orbit of any debris.

Question 30

Ellipse

Answer 30

an oval shaped orbit of each planet.

Question 31

Axis

Answer 31

imaginary line that passes through the center of the Earth from its North pole to the South pole.
