Answers
1
The outermost rigid layer of Earth that includes the crust and the upper mantle is called _____
lithosphere
inner core
mantle
oceanic
2
If the ocean floor is always making new crust, why isn't the earth getting bigger any bigger?
the Earth is shrinking everywhere else due to its age
the Earth IS getting bigger
because old crust is subducted and melted back into the mantle
the ocean only makes new crust once very couple billion years
3
Scientist who came up with the hypothesis of Continental Drift was who?
Alfred Nobel
Alfred Marshall
Alfred Pennyworth
Alfred Wegener
4
How does slab pull contribute to plate movement?
It causes convection currents in the mantle
Gravity helps push the plate near the ridge away from the ridge
Gravity helps pull the plate near the subduction zone into the mantle
It forms tsunamis
5
Hypothesis that states that the continents once formed a single Landmass then broke apart:
Plate Movement
Continental Drift
Lithosphere Displacement
Laurasia
6
The type of rock formed by extreme heat and pressure, sometimes taking millions of years to form:
igneous rock
metamorphic rock
sedimentary rock
7
At mid-ocean ridges...
the crust is older

14
How does ridge push contribute to plate movement?
It forms tsunamis
Gravity helps push the plate near the ridge away from the ridge
Gravity helps pull the plate near the subduction zone into the mantle
It causes convection currents in the mantle

they measure the amount of damage
they triangulate seismic waves
it is the spot where the earth broke open
the measure the speed of seismic waves
