full moon
True or False
Most "gas giants" are closer to the sun.
False
True or False
The moon has less gravity (less gravitational pull) than the Earth because it has less mass than the Earth.
True
How long does it take Earth to orbit the sun?
365.25 days
The force that keeps the planets in their orbit
Gravity
What is a neap tide?
The sun and moon are at a right angle to each other lessening the extremity of the tides.
What happens when Earth rotates on its axis once?
one day/ 24 hours
Day and night are caused by this movement of the Earth
What is rotation on its axis?
The Earth takes one year to make one of these around the sun
A revolution
A __________ occurs when the moon comes between the sun and the earth and the Moon's shadow falls on Earth, blocking the Sun from Earth.
A solar eclipse
Which season has the least amount of daylight?
Winter
How long does it take for the moon to orbit earth?
28 days
What are moon (lunar) phases?
The changes in how the moon looks to people on Earth
The first day of summer in the Southern Hemisphere is in what month?
December
The winter solstice in the Southern Hemisphere
June 21st
These changes are caused by Earth’s tilt on its axis and its revolution around the sun
Seasons
What is an orbit?
Earth’s path around the sun
What is a spring tide?
The sun and moon are aligned, working together to create more extreme high and low tides.
How long does it take the Earth to rotate on its axis?
24 hours
How are tides caused?
The moon's gravity pulls the Earth's oceans towards it creating bulges of high tides on the sides of Earth closest to the moon.
The star at the center of the solar system
The sun
When the moon passes directly behind the Earth and into its shadow
lunar eclipse
What phase of the moon do we get Solar eclipses?
New Moon
What is the tilt of the Earth?
23.5 degrees
What is the darkest part of the shadow during an eclipse?
Umbra
When the north pole is tilted directly toward the sun, the season it's experiencing is _____.
Summer
What season is it in the southern hemisphere when the north pole is tilted away from the sun?
Summer
How does gravity affect the motion of planets?
Gravity causes the motions of planets, stars, and galaxies. It's why the Moon orbits around the Earth, and the Earth orbits around the Sun, and the solar system orbits around the galaxy. The gravitational force depends on two factors, mass of an object and distance between objects.
What is the term that means Sun centered model?
Heliocentric
Helios is the greek god of the sun
Centric meaning centred
List the moon phases in order
New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter, and Waning Crescent.
What is the term of a metamorphic rock when the minerals align?
Foliation
Why is it warmer on a summer’s day than on a winter’s day? You may draw a diagram to help you explain
What is the imaginary line that divides the earth into two hemispheres?
The equator
Which is more eccentric and why?
Asteroid: 0.056
Planet: 0.096
Planet, its eccentricity is closer to 1.
What is an Isobar?
A line that connect points of equal pressure.
