What two items can scientist use to study Earth's climate from over time?
Tree Rings and Ice Cores
What land forms are formed by the movement of tectonic plates? (Name at least 2)
Mountains
Volcanoes
Earthquakes
This type of volcano has a broad base and gently sloping sides. Covers large areas.
Shield volcano
What type of plate boundary do the plates move towards each other?
Convergent
Why do most Earthquakes take place at tectonic plate boundaries?
They take place where the motion of tectonic plates transfers energy to rock
Fossils can tell scientist
about the environment long ago, how the Earth changed, how plants and animals have changed
Tree rings are able to tell scientists what three things?
age of tree, weather conditions, and climate in an area
A _________ is an opening in the Earth's crust that allows lava and ash to be released.
Vent
What is the theory of continental drift?
the present continents appear to fit together as pieces of a larger land mass
How can the epicenter of an Earthquake be located miles away from a fault line?
Fault line do not extend down into the Earth in a perfectly straight line.
Fossilized evidence that formed in sedimentary rock showing animal activity.
Trace Fossil
Which tectonic plate do we all live on?
North American
What is the relationship between magma and lava?
Lava is magma that has reached Earth's surface.
Tectonic plates can be made of continental crust or oceanic crust or a combination of the two. Besides their locations, how else are these two kinds of crust different?
Continental crust is thicker than oceanic crust

rebound
