From the Earth to the Sun
The tilt of this imaginary line is what causes seasons on Earth.
What is the axis?
This is how much of the lunar surface is receiving sunlight at any given time.
What is half?
This planet’s surface is where most humans live.
What is Earth?
This layer of gases around a planet can act as a blanket, holding in heat and reflecting cosmic rays.
What is an atmosphere?
This cloud of dust and gas will clump together due to gravity, leading to the birth of a star.
What is a nebula?
These large dark areas on the moon are made of ancient basalt.
What are maria?
This is the amount of the Earth that is experiencing night at any given time.
What is half?
This moon phase is the only one during which a solar eclipse is possible.
What is a new moon?
This galaxy is where you are currently living.
What is the Milky Way galaxy?
Any object which orbits a planet is known as a _______.
What is a satellite?
The process of particles of rocks and gas clumping together.
What is accretion?
This principle explains that a feature which cuts through another must be younger than the feature it cuts.
What is the Principle of Crosscutting Relationships?
This measurement determines how intense the light from the sun can be in an area of Earth’s surface.
What is the solar angle?
This moon phase is the only one during which a lunar eclipse is possible.
What is a full moon?
This large area includes all of the galaxies, stars, nebulae, black holes, etc. that are known to humans.
What is the universe?
The number of exoplanets orbiting a distant star can be identified by the number of these lines on a brightness graph.
What are transits?
The gravity on these types of planets is probably too high to allow for life to exist on their surface.
What are gas giants?
These lines radiate from a crater and indicate a larger meteoroid.
What are rays?
On June 21st each year, this location on Earth receives 24 hours of daylight.
What is the North Pole?
During this moon phase, the visible part of the moon is shaped like a banana on the left side of the lunar surface.
What is waning crescent?
This group of galaxies includes our own galaxy.
What is the Local Group?
The time that it takes a planet to revolve around its star:
What is orbital period?
The extreme pressures of gravity in the center of a nebula can lead to fusion, which causes this step in the life cycle of a star.
What is the star turns on?
This ratio represents the size of a crater relative to the meteoroid that formed it.
What is 20:1?
This measurement (in degrees) of a location relative to the Equator can help determine how many hours of daylight the location receives throughout the year?
What is the latitude?
This is how long it takes for the moon to revolve around the Earth.
What is one month (28-29 days)?
This named star holds Earth, Io, Ceres, and Halley’s Comet (among other objects) within its gravitational field.
What is Sol?
In general, this is the relationship between a planet’s temperature and its distance from its star.
What is the further it is from the star, the colder the temperature?
During this stage of the formation of a solar system, gravity launches smaller objects further into space, and they can even escape the solar system.
What is flinging?
This is one reason why a moon or planet may have less craters than another moon/planet of similar size.
What is an atmosphere (or weathering and erosion)?
