Space And Earth Systems

Front 1

meteoroid

Back 1

a sand grain to boulder sized rocky body that travels through space

Front 2

meteor

Back 2

A bright streak of light that results when a meteoroid burns up in the Earth's atmosphere

Front 3

meteorite

Back 3

a meteoroid that reaches Earth Surface without burning up

Front 4

terrestrial planets

Back 4

the four small, dense , rocky planets that orbit closest to the SUN.

Mercury, Venus, Earth and Mars

Front 5

Gas Giants

Back 5

Jupiter, Saturn, Uranus and Neptune

They have deep, massive gas atmospheres, which are made up mostly of hydrogen and helium. Gas giants are cold.

Front 6

Jupiter

Back 6

largest planet in our solar system

has the most moon over 60 moons

Front 7

Saturn

Back 7

second largest planet and is known for its

Front 8

Uranus

Back 8

tilted at almost a 98 degrees; it appears to be tilted on its axis as it revolves around the sun

Front 9

Neptune

Back 9

is the most distant planet from the sun. It is 30 times farther from the sun than the Earth is.

Front 10

heliocentric

Back 10

Earth and other planets orbit the sun

Front 11

Geocentric

Back 11

models that put the Earth in the center

Front 12

rotation of the Earth

Back 12

causes day and night

causes the sun to appear to rise in the east and set in the west

Front 13

revolution of the Earth around the SUN

Back 13

determines the length of a year

affects the season to a small degree

Front 14

the tilt of the Earth on its Axis

Back 14

causes the seasons by changing the angle at which the Sun's rays hit the Earth

Front 15

full moon

Back 15

We see a full white circle in the sky at night

Front 16

waxing crescent

Back 16

light on right and light will increase tomorrow night

Front 17

first quarter

Back 17

1/2 of the moon is showing on the right side

Front 18

Waxing Gibbous

Back 18

3/4 of the moon is showing on the right side

think "Wax on"

Front 19

Waning Gibbous

Back 19

3/4 of the moon is showing on the left side of the moon

Front 20

Third Quarter

Back 20

1/2 of the moon is showing on the left side of the mood

Front 21

Waning crescent

Back 21

area of the near side of the moon in sunlight continues to shrink

Front 22

New Moon

Back 22

no moon is visible in the night sky. The Moon is between the Sun and the Earth

Front 23

Solar eclipse

Back 23

When the moon is directly between the Sun and the Earth, the shadow of the moon falls on a part of the Earth causing this type of eclipse

Front 24

Lunar eclipse

Back 24

When the Earth is between the Sun and the moon and covers up part of the Sun's rays from hitting and reflecting back to us on Earth

Front 25

Tides

Back 25

are daily changes in the level of ocean water caused by the gravitational interaction between the Moon and the Earth; the moon is mainly responsible for tides on Earth

Front 26

High tide

Back 26

is the when the waters of the Earth bulge toward the Moon (they are being pulled by the moon's gravity)

Front 27

Low tide

Back 27

is when the moon is closest to the opposite side of the Earth.

As the moon moves around the Earth and the Earth rotates, the tidal bulges move around Earth. These bulges follow the motion of the moon.

Front 28

Neap tides

Back 28

occur when the Sun, Earth and moon form a 90* angle. During these tides the gravitational effects of the sun and the moon on Earth do not add together as they do during spring tides.
