Volcanes are shown along Japan, where the Eurasia and Philippine plates meet. What is happening there?

The Philippine plate is subducting under Eurasia as they converge

Tectonic plates are...

Parts of the lithoshpere that float on the asthenosphere

What is the difference between the epicenter and the focus?

Epicenter is on the surface, focus is where rock slides making EQ.

Mountains are a product of continental-continental convergence because...

Compression pushes two plate together

The plate moving right is a/an ________ and is subducting because...

Oceanic subducts because it is more dense than continental

The order of Earth's layers from least to most dense

Crust, Mantle, Outer Core, Inner Core

How are convection currents related to plate tectonics?

The currents in the mantle move the plates

Which is true about P-waves and S-waves?

P waves arrive first and fastest

Seismic waves help scientists determine....

ALL OF IT... EVERYTHING - SEISMIC WAVES RULE!!!

Answers

1
What type of seismic wave is most destructive?
Secondary
Primary
Surface
Ocean
2
Volcanes are shown along Japan, where the Eurasia and Philippine plates meet. What is happening there?
The Philippine plate is subducting under Eurasia as they converge
Earthquakes occur creating volcanoes
Mountains form as continental plates collide
Mid-ocean ridge forms as Philippine slides away from Eurasia
3
Tectonic plates are...
Earth's crust floating on the liquid outer core
Shaking glass that food can be put on
Earth's continents that float on the ocean
Parts of the lithoshpere that float on the asthenosphere
4
What do they call the location where two plates interact?
Boundaries
Subduction zones
Forces
Mid-ocean ridges
5
Force present at a transform boundary...
Compression
Shear
Earthquakin...AHHHHHHHH
Tension
6
Convergent boundaries that produce mountains are...
Oceanic subducting under Continental
Continental into Continental
Oceanic pulling from oceanic
Oceanic sliding past Continental
7
The ____ layer is least dense and the ____ layer is the densest
Red, Yellow
Red, Blue
Green, Blue
Blue, Red
8
What is the difference between the epicenter and the focus?
Epicenter is fault and focus is center of EQ.
Epicenter is on the surface, focus is where rock slides making EQ.
They are the same... so trivial!!!
Epicenter is point of EQ and focus is center of surface
9
Mountains are a product of continental-continental convergence because...
Shearing slide the two plates past each other
Tension pulls the plates apart
Compression pushes one plate under the other
Compression pushes two plate together
10
What type of boundary is shown?
Ocean-Ocean Convergent
Continental-Continental Convergent
Transform
Divergent
11
This type of wave can pass through the outer core
Primary
Secondary
Rayleigh
Ocean
12
If the cup modeled Earth's layers, where do convection current occur?
yellow
blue
red
green
13
The plate moving right is a/an ________ and is subducting because...
Continental because continental is more dense than oceanic
Continental because it is more dense
Oceanic subducts because it is more dense than continental
Oceanic because it is less dense
14
The order of Earth's layers from least to most dense
Mantle, Crust, Outer Core, Inner Core
Crust, Mantle, Outer Core, Inner Core
Crust Mantle, Inner Core, Outer Core
Crust, Outer Core, Mantle, Inner Core
15
Volcanoes and mountains form due to...
Mountains are just dead volcanoes
shearing forces
divergent boundaries
compressional forces
16
How are convection currents related to plate tectonics?
Convection transfers heat causing mantle to be warm
Less dense magma rises pushing up thru volcanoes
Creates new crust at volcanic chains (Ring of Fire)
The currents in the mantle move the plates
17
What type of boundary is pictured?
Transform
Continental-Continental convergent
Continental-Oceanic convergent
Divergent
18
Which is true about P-waves and S-waves?
P waves are second to arrive at station
S waves travel through solids and liquids
P waves arrive first and fastest
S waves are slower and the least destructive
19
Seismic waves help scientists determine....
ALL OF IT... EVERYTHING - SEISMIC WAVES RULE!!!
Epicenter
Direction of energy in Earthquake
Layers of Earth
20
What is formed at the boundary shown?
Subduction zone
Mountain
Earthquake
Mid-ocean ridge
