Answers
1
Which of the following is
NOT TRUE
about the Crust?
It is made of metal.
It is the least dense layer of Earth.
It is the coolest layer of Earth.
It is a solid that is broken into pieces called plates.
2
Which of the following is
NOT
TRUE
about the Mantle?
The upper mantle is part of the Lithosphere.
It is a solid.
Convection currents that move the crust happen here.
It is an amorphous solid (not truly a liquid or a solid).
3
What forms at transform boundaries?
Earthquakes
Mountains
Volcanoes
Rift Valleys
4
What forms when oceanic crust diverges?
Mountains form
Creates mid-ocean ridges (seafloor spreading) & new crust
New crust
Islands are created
5
What forms when continental crust diverges?
Islands
Volcanoes
Rift Valleys and new crust
Folded Mountains
6
What forms when an ocean plate and continental plate converge?
Rift Valleys
Subduction creates volcanic island arcs.
Subduction creates volcanic mountain ranges.
Seafloor Spreading
7
How do Earth's tectonic (lithospheric) plates move?
Convection in the core causes the plates to move.
The plates move as they float along the oceans.
The plates do not move.
The core heats the mantle which causes convection currents.
8
What evidence did Wegener find to support his theory of Continental Drift?
Rare phytoplankton found in Australia.
Matching ice sheets in Africa, Antarctica, SA, and Australia.
Matching rock layers and fossils on multiple continents.
Plant fossil only found in Asia.
9
What is the correct order from outermost to innermost?
Crust, Mantle, Outer Core, Inner Core
Crust, Mantle, Inner Core, Outer Core
Inner Core, Outer Core, Mantle, Crust
Inner Core, Mantle, Outer Core, Crust
10
Why is the Ring of Fire, an area in the Pacific, where many earthquakes and volcanoes happen?
Plates diverging
Transform boundaries surround this region
There are numerous tectonic plate boundaries along the edges
Plates converging
11
Which of the following is
NOT TRUE
about the Inner Core?
It is the most dense layer.
It is liquid metal.
It is solid metal.
It is the hottest layer of Earth.
12
Why did other scientists not support Wegener's theory of Continental Drift?
He could not explain how the plates moved.
He had no evidence to support his claim.
His evidence supported the idea that the plates hadn't moved.
He could explain how the plates moved.
13
What forms when 2 Oceanic Plates of different densities converge?
Sea Floor Spreading
Rift Valleys
Subduction creates trenches and volcanic island arcs.
Mountain ranges form in the ocean.
14
Which of the following
IS TRUE
about the Outer Core?
It is part of the Asthenosphere.
It is solid metal (iron and nickel).
Convection currents that move the crust happen here.
It is liquid metal (iron and nickel).
15
What forms when continental crust converges with continental crust?
Islands
Folded Mountains
Rift Valleys
Volcanoes
16
New crust is created in the ocean at mid-ocean ridges. What does this do to older rocks?
Melts it and adds it to the new crust formation.
Pushes older rocks to the side causing seafloor spreading.
It makes the layer of crust thicker.
Forces old crust to bunch together causing mountains.
17
What forms when 2 Oceanic Plates of similar densities converge?
Sea Floor Spreading
Subduction creates trenches and volcanic island arcs.
Rift Valleys
Mountain ranges form in the ocean.
18
What is the Lithosphere?
The Lithosphere is the crust and upper layer of the mantle.
The Lithosphere is the sphere of earth containing soil.
The Lithosphere is the mantle.
The Lithosphere is the crust.
