Chapter Study Guide. EARTH-SUN-MOON

Quick Vocabulary

Lesson 1 Eath’s motion p 8-16

equator imaginary line that divides Earth into its northern and southern hemispheres

equinox day when Earth’s axis is not leaning toward or away from the Sun

orbit path an object follows as it moves around another object

revolution motion of an object around another object

rotation spinning motion

rotation axis line on which an object rotates

solstice day when Earth’s rotation axis is the most toward or away from the Sun

Lesson 2 Eath’s moon p 18-24

maria large, dark, flat areas on the Moon

phase lit part of the Moon or a planet that can be seen from Earth

waning phase occurs when less of the Moon’s near side is lit each night

waxing phase occurs when more of the Moon’s near side is lit each night

Lesson 3 Eclipses ad Tides p 26-32

lunar eclipse occurs when the Moon moves into Earth’s shadow

penumbra lighter part of a shadow where light is partially blocked

solar eclipse occurs when the Moon’s shadow appears on Earth’s surface

tide daily rise and fall of sea level

umbra central, darker part of a shadow where light is totally blocked

Things you need to know!

Explain that the planets in our solar system revolve around the sun.

• Describe rotation as the process of Earth spinning on its axis.
• Define a day as the amount of time (about 24 hours) it takes Earth to

make one complete rotation.

• Understand that while Earth is rotating on its axis, it is also revolving

around the sun.

• Explain that Earth revolves around the sun every 365.25 days which

we refer to as a year.

• Understand that the different seasons are the result of the position of

Earth’s tilting axis relative to the sun.

• Differentiate between the terms solstice and equinox.
• State when the winter and summer solstices occur in the northern

hemisphere, and describe how the amount of daylight differs between

the two.

• Explain the causes of tides.
