Cratering When objects in the solar system smash into a planet creating an erosion
Crater when an object impacts the planet id deosnt matter the angle it will get exactly the same circle
Ejecta anything that comes out of the whole of the crater
Meteroids interplanetary debris before it hits the earth
Meteorites stones and iron more destruction
Comet ice balls
Asteroid any rock in space with a certain zone between mars and jupiter
Geologic time scale earths history divided up based on earth events
Relative Age the age of an object in relation to other objecs
Divisions of time on earth Epoch, period, Era, Eon
Theory of Plate Tectonics Plate tectonics are how the earth crust moves all the time
Lithosphere earth's crust and the upper mantle
Asthenosphere layer of rock below the lithosphere, just like putty
Divergent boundary A boundary between plates that are moving away from each other. New crust created, mid ocean ridges
Convergent boundary A boundary between plates that are moving toward each other. Includes collisional boundary and subduction zones.
Transform boundary plates slide past each other horizontally, creates earthquakes
Seafloor spreading new seafloor is created through the divergent boundary
Law of superposition oldest crater is on bottom
Original horizontality sedimentary layers were originally deposited horizontally
Lateral continuity sedimentary layers extend laterally to the edge of their basin or thin to nothing
Unconformities A principle that geologic process that occurred in the past can be explained by current geologic process
Nonconformity rock is uplifted, then eroded
Angular unconformity rock is folded or tilted
Disconformity boundary between horizontal layers of old sedimentary
Cross-cutting relationships any feature that cuts across a rock is younger than the rocks it cuts across
Kepler's first law Law states that planets orbit in ellipses, with the sun at one focus.
Kepler's second law Law that states that planets speed up as they get nearer the sun and slow down as they move farther from the sun
Kepler's third law Law that states that the square of a planets period is proportional to the cube of the planets orbital radius

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
