Which of the following statements is TRUE concerning convection?
When matter heats up, it expands and becomes more dense.
When matter heats up, it contracts and becomes more dense.
When matter heats up, it expands and becomes less dense.
When matter heats up, it contracts and becomes less dense.
Which of the following is true about subduction of plates? Choose the one best answer.
Oceanic plates are denser and thinner than continental plates; oceanic plates are subducted under continental plates.
Oceanic plates are thicker and more dense than continental plates and therefore subduct under continental plates.
Continental plates are more dense than oceanic plates and therefore subduct under oceanic plates.
Oceanic plates are less dense than continental plates; therefore oceanic plates subduct under continental plates.
What causes plates to move?
energy from the sun
convection currents in the asthenosphere
gravity and friction
natural disasters such as volcanic eruptions and tsunamis
The process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle is known as
uplift
convection
seafloor spreading
subduction
About 90% of the world’s earthquakes and 75% of the world’s volcanoes take place in the “Ring of Fire”. Why is this the case?
It is a place where there is large amount of plate movement.
It is very warm in this region of the world which allows for high levels of convection.
It is the region of the world which is most affected by the weather phenomenon “El Niño”.
It is the location of the largest ridge system, the Mid-Atlantic Ridge.
A fracture or break in the crust of the Earth
fault
epicenter
focus
uplift
How is it possible for new crust to be formed without increasing the surface area of the Earth?
Crust is recycled in subduction zones at the same time it is created at mid-ocean ridges
New crust is underwater where it sinks
New crust breaks more easily than old crust
The oldest crust just breaks apart as the plates move
1. Rock sediments that travel down a mountain, sand being blown across the beach, and mud sliding down a hill are all examples of
pressing and cementing
erosion
part of the rock cycle
fossil formation
The remains of living things that died long ago are often found in what type of rock?
igneous rocks
sedimentary rock
metamorphic rock
all rocks
The cooled and hardened magma from volcanoes form what rocks?
igneous
sedimentary
metamorphic
fossils
Hot, molten rock inside the earth is called ...
lava
magma
igneous rock
minerals
Once magma reaches the earth's surface, it is called __________.
a vent
minerals
igneous rocks
lava
What are the two types of crust?
What is the MAIN way rocks are classified?
Their color and shapes
How they form
Texture
Composition
What do scientists know about an undisturbed sequence of rocks based on superposition?
Older rocks are on top of younger rocks
Younger rocks are on top of older rocks
Older rocks have eroded away
Younger walks get deposited and do not stay
How does the law of crosscutting relationships explain the age of a fault caused by an earthquake?
The fault is older than the rocks above it.
The fault is younger than the rocks above it.
The fault is older than rocks it cuts through.
The fault is younger than the rocks it cuts through.
The asthenosphere can best be described as
The rigid rock material found in the upper mantle
the plastic-like area of the upper mantle that the lithosphere "floats" on
The melted rock material found deep in the mantle
The liquid iron and nickel that move in the core
Which statement best compares and contrasts the inner and outer cores
The inner and outer core both are made of iron and nickel, but the metals are in a liquid state in the outer core. On the other hand, the iron and nickel are solid in the core due to the high pressure
The inner core is made of solid iron and nickel The outer core is made of liquid iron and nickel.
The outer core is solid iron and nickel, whereas the same material is in a liquid state in the inner core because it is so hot at that depth.
The inner and outer core are both metal and part of the layers of Earth. They are different too.
5. Scientists' knowledge of the Earth's interior has come primarily from...
a. studying magnetic reversals in oceanic crust
b. using a system of satellite called the giobal positioning system
c. studying sesmic waves generated by earthquakes.
d. studying the pattern of fossils on different continents.
Where does the heat come from that drives convection currents in the asthenosphere?
The sun

the mantle
the core

system
energy
matter
element
