Plate Tectonics
What was the original theory of Plate Tectonics called?
What is Sea-floor Spreading?
When sediment stops moving and collects in a new area this is called....?
Deposited / Deposition
Please, take another turn!
This type of dating refers to being compared to something else
What is Relative Dating
A solid, naturally-formed substance that always has the same composition and the same properties.
What is a Mineral?
Impression or other preserved sign of activity such as feeding, scratching, burrowing, walking, or resting.
What is a Trace Fossil?
Daily Double!!
What is the Earth's outer crust called?
What is a Lithosphere?
When rocks are broken down into smaller pieces.
What is Weathering?
What is the definition of Aesthenosphere?
What is the Earth's upper mantle?
Rock formed from magma or lava.
What is Igneous?
Hollow space left in a rock by animal or plant remains that have dissolved.
What is a Mold Fossil?
What types of currents move energy around a surface to heat it (or, in some cases, cool it down)?
What are Convection Currents?
When molten rock from inside Earth moves through cracks in the rock layers. This molten rock will sometimes reach and break through the surface.
What is a/an Intrusion?
These are a series of shields that are stated to be currently floating throughout the Earth today.
What are Tectonic Plates
Molten rock within Earth.
Daily Double!
Preserved remains of the plant or animal itself, or the preserved parts of the animal or plant like bones, teeth, and shells, or the imprint of parts of the animal or plant.
What is a Body Fossil?
What type of plate boundary "collides" with other plates?
What is Converge.
Daily Double!!
When small pieces of rock (sediment) are moved around by wind and/or water.
What is Erosion?
What type of plate boundary "separates", "divides", or moves away from other plates?
What is Diverge.
A naturally formed combination of minerals and other natural materials.
What is Rock?
Please Take Another Turn!!
Daily Double!!
A fossil that provides evidence for organisms transitioning from living in water to land.
What is a Transitional Fossil?
What are the three types of plate boundaries called? (Hint--how do they move?)
What are: diverge, converge, transform.
Which type of plate boundary is associated with "Subduction" and the creation of volcanoes?
What are Convergent/Converging.
What type of plate boundary "slides past" one another?
What is Transform?
Rock formed from existing rock; heat and pressure cause the minerals to form new combinations or new crystals.
What is Metamorphic?
Please Take Another Turn!!
When molds fill in with minerals or sediments that later harden, this results in which type of fossil?
What is a Cast Fossil?
