Objective

SWBAT: Describe the features, formation, and characteristics of the moon on a foldable.

InstructionsCreate a foldable with 3 columns

Label the columns

1. The Moon’s Surface

2. Characteristics of the Moon

3. The Origin of the Moon

The Moon’s SurfaceMaria- Dark, flat surfaces on the moon

Latin word for “seas”Hardened rock from lava flow that occurred 3-4 billion years

ago

Craters- Large, round pits on the moon’s surfaceSome craters are hundreds kilometers acroosCaused by the impact of meteors ( chunks of rock or dust

from space)

The Moon’s Surface Cont.Highlands- Light colored features on the surface of the moon known as highlands or mountains

Characteristics of the Moon Size and Density

3,476 kilometers in diameter ( a little less than the distance across the United States)

The moon only has 1/80th the mass of Earth

Temperature and Atmosphere Temperature on the moon’s surface ranges from -180 degrees Celcius to

130 degrees Celcius The moon has no atmosphere because of weak gravity that allows gases

to escape

Characteristics of the Moon Cont.Water• There is no liquid water

on the moon’s surface• There is evidence of

large patches of ice near the poles on the moon

Origin of the MoonCollision-ring theory

When Earth was very young, the solar system was full of rocky debris (some the size of planets)

Scientists theorize that a planet-sized object collided with Earth to form the moon

Material from the object and Earth’s outer layers was ejected into orbit around Earth where it formed a ring.

Gravity caused this material to combine to form the moon
