Waves travel at different speeds through the Earth's interior. What property distinguishes the Earth's crust, mantle, and core?
mass
pressure
composition
temperature
Like the layers of the ocean, the Earth's crust is divided into part based on physical properties. Which of the following statements best describes a layer of the Earth?
The asthenosphere has the greatest density
The mesosphere has the least density
The outer core has the least density
The inner core has the greatest density
Where on the ocean floor is new ocean crust being created?
the continental shelf
the continental slope
the deep ocean trenches
the mid-ocean ridges
The movement of the two continents as shown in picture can best explained by
plate tectonics
coastal flooding
magnetic changes
volcanic eruptions
Most earthquakes and volcanoes occur in areas of the Pacific Ocean called the "Ring of Fire." Scientists agree that the reason for this is
That part of the Earth is hotter than all other parts of Earth.
A large number of people live in these areas.
The ocean weighs so much that it forces magma up.
plate boundaries are located in those areas
Earthquakes are most likely to occur where
the density cracks thin areas of Earth's crust
heat causes the mantle to expand
there are plate boundaries
bubbles of magma rise to the surface
Sea-floor spreading makes
new oceanic crust
oceanic trenches
magma
new volcanoes
The continent move apart at a rate of
feet/year
meters/year
millimeters/year
centimeters/year
The layer of rock that forms Earth's outer surface.
inner core
skin
crust
mantle
The relatively thick part of the Earth's crust which forms the large land masses
crust
oceanic crust
asthenosphere
continental crust
The transfer of heat by movement of a fluid
conduction
radiation
convection
thermal energy
A layer the Earth that is made of liquid iron and nickel ; responsible for Earth's magnetic field
crust
mantle
inner core
outer core
heat currents in the magma that move from the interior of the Earth to the surface and drive plate tectonics
ocean currents
convection currents
ocean currents
wind currents
A dense ball of solid iron and nickel at the center of the Earth
outer core
mantle
crust
inner core
How is Earth’s magnetic field similar to that of a magnet?
It is hundreds of miles long.
It is shaped like a horseshoe.
It has North and South poles
It is made in Earth’s core.
What is our best evidence that Earth has a magnetic field?
A compass needle lines up with it.
Earth’s oceans all have currents.
All things fall toward Earth’s center.
Winds blow from east to west.
Convection currents occur due to...
rotation of earth
differences in temperature and density
electrons moving
gravitational pull
Which of the following is one reason Earth's tectonic plates to move?
energy from the Sun
magnetic Pole Reversal
convection currents in the mantle
faults in Mountain Ranges
Convection cycles move in the mantle. How does this affect the crust?
crust has no motion
crust moves in random directions
crust moves in same direction convection cycle moves
Name the type of heat transfer shown in the picture.
convection
conduction
radiation
