Seasons
What are reasons why the earth has seasons
Tilt and revolution of the earth
Tides are caused by what two things and which one is stronger
Moon and sun with the moon being stronger
The moon is illuminated by what
the sun
Definition of Rotation
Spinning Motion of a planet on its axis
How long does it take for the moon to complete its cycle
28 days
Why is it the northern and southern hemispheres have oposite seasons
The tilt of the earths causes one hemisphere to have more direct sunlight as it revolves around the sun
What is the difference between and spring and a neap tide
The spring tides have the greatest difference between high and low tides
What happens during a solar eclipse
the moon blocks out the sun
Definition of Revolution
Movement of an object around another object
What is the heliocentric model
The model that has the planets orbiting the sun
When does an equinox occur
when the daylight is equal to nighttime
How many high tides will be experience in 24 hours
2
What happens during a lunar eclipse
the earth blocks out the light from the sun onto the moon
What degree tilt does the earth have
23.5 degrees
Earths only natural satellite is what
the moon
When it is Winter in south america what would be the season in north america
summer
Why is it we have 2 high tides in 24 hours if the moon is only over head once
Because the moons gravitational pull is still is effecting the oceans on the other side of the earth causing the water to pull towards the moon
How does the moon impact earth
ocean tides, stabilize the tilt of the earth, and inspire cultures and calendars
How many planets in our solar system
8
What is the definition of homologues structure
When two structures have similar makeup and are from a common ancestor
Why is it as you go closer to the equator the seasons become lease extream
Because areas around the equator experience less change in tilt while the earth is revolving around the sun
Why is the Spring tide stronger then the neap tide
The spring tide has both the sun and moon in alignment that allows them to both have a gravitational effect on the earth
Three types of solar eclipes
solar, lunar, and hybrid
What keeps planets revolving around the sun
Because of the law of inertia( an object in motion stays in motion) and the gravitational of pull of the sun
Why is it we don't see organic mater in fossils
Fossils are made of inorganic material like rocks and minerals
