Vocabulary
Preserved remains or traces of a plant or animal that once lived long ago
Fossil
arrow pointing toward one another
seafloor spreading
List the four types of fossils.
mold, cast, true form, and trace
What is the geologic time scale?
Common system used to organize Earth's history using fossils and rocks.
What are tectonic plates?
Large pieces of Earth crust that can move
Draw a picture of a transform plate boundary using boxes and arrows to show the plate's direction.
arrows up and down (sliding past on another)
Where is new seafloor created?
Mid- Ocean Ridge
True or False: Fossils are very common and most things that die become fossilized.
False
What is an igneous rock intrusion?
When magma comes up through previous rock layers and hardens into new rock.
Where are tectonic plates located?
Lithosphere
Draw a picture of a divergent plate boundary using boxes and arrows to show the plate's direction.
Arrows pointing in opposite direction from one another
Fossils, oil deposits, coal, and landmarks located all over the world are all evidence that Earth was once one large supercontinent called ________.
Pangea
What is absolute vs relative dating when it comes to fossils.
Absolute dating is the exact age of the fossil/rock and relative dating compare rocks/fossil to decide which is older or younger.
Where are the oldest layers of rock found on land? Draw a picture if needed.
At the bottom, and they get younger as your go up.
What is it called when one tectonic plate sinks below another plate.
Subduction
What can happen on land when two plates slide past one another.
Earthquakes
Why are convection currents important to tectonic plates?
True or False: The fossilization process can happen in 100 years
Where are the oldest layers of rock found on the ocean floor? Draw a picture if needed.
Farthest away from the mid-ocean ridge
Slow, and circular movement caused by heat rising and cool material sinking is called _____________.
Convection Currents
What type of plate boundary causes mountains to form?
Convergent
Explain how Earth's crust is recycled.
Seafloor spreading occurs at the mid-ocean ridge and the new crust pushes the old crust farther away from the ridge until it is eventually recycled into the mantle through subduction.
Place the following statements in the order in which they'll happen.
1. Dinosaur becomes a fossil
2. Dinosaur roamed the Earth.
3.Dinosaur fossils are found in multiple continents by paleontologists.
4. Dinosaur dies :(
5. Earth's continents drift apart.
2, 4, 1, 5, 3
Draw three rock layers and a magma intrusion. Label the layers from oldest to youngest.
