Which force is responsible for the movement of tectonic plates?
Gravity
Convection Currents
Electricity
Magnetism
Mountains in the Himalayans are increasing elevation due to-
Sea Floor Spreading
Earthquakes
transform plates faulting
plates colliding
Mountains are created by which boundary-
convergent
divergent
transform
What geological feature is created at the MID OCEAN RIDGE?
Mountain
Volcano
Plateau
What geological process created the Himalayan Mountain Range?
earthquake in a subduction zone
tectonic plate over a hot spot
movement at a transform fault
two plates converging(moving toward another)
The diagram below models the movement of two tectonic plates.
What is occurring as a result of the plate collision?
A mid-ocean ridge is forming.
Subduction is occurring because oceanic crust is denser than continental crust. This tectonic plate action forms a trench and a volcano.
A divergent boundary is forming.
A transform boundary is forming due to two plates sliding past one another.
Which piece of evidence did Alfred Wegener NOT use for his theory of continental drift?
Fossils
Continental Fit
Glacial
Topographic Maps
Alfred Wegener noted that fossils from a particular type of reptile were found on both sides of the Atlantic Ocean. Which of the following would be the best explanation of how this occurred?
The reptiles swam across the ocean.
The Atlantic Ocean did not exist in earlier times.
The reptiles walked across a giant land bridge that has weathered away.
The reptiles walked across an ice bridge located near the equator.
In an area known as The Ring of Fire, volcanic island chains have formed in the Pacific Ocean. What most likely caused this to happen?
Convergent plate boundary
Divergent plate boundary
Transform plate boundary
Mantle hot spot
Which of the following is NOT evidence that Pangaea once existed?
Mountain ranges on continents line up
Fossils of reptiles that can only be found on one continent were found on other continents
Fossils of tropical plants were found in cold climates
There were lines in the ocean from where the continent moved along the bottom
Why are the oldest parts of the ocean floor no older than about 200 million years old?
That is how long it takes for sand to completely cover the ocean floor
That is how long it takes for new crust to form, move across the ocean and sink into a trench
Underwater volcanoes erupt every 200 million years and create a new ocean floor
Which is the FIRST step of sea-floor spreading?
The molten material cools and hardens, forming a strip of rock along the ocean floor
The strip of rock moves away from the ridge
Molten material from inside Earth rises to the ocean floor at a mid-ocean ridge
At which boundary do two plates move away from each other
Divergent
Convergent
Transform
At which boundary do two plates move towards each other
Divergent
Convergent
Transform
At which boundary do two plates slip past each other
Divergent
Convergent
Transform
Your classmate tells you that Earth's surface is broken into different plates that move. What Theory are they telling you about?
Plate Tectonic Theory
Continental Drift Theory
Convection Theory
The movement of matter due to differences in density; the transfer of energy due to the movement of matter
plate tectonics
convergent boundary
convection
divergent boundary
The process by which new oceanic lithosphere (sea floor) forms when magma rises to Earth's surface at mid-ocean ridges a solidifies (hardens) as older, existing sea floor moves away from the ridge.
sea-floor spreading
transform boundary
plate tectonics
convection
The theory that Earth's outer layer is made up of large moving pieces called tectonic plates; the theory explains how plates interact and how those interactions relate to processes such as earthquakes and mountain building.
mid ocean ridges
plate tectonics
divergent boundary
convection theory
The San Andreas fault in California is on this type of plate boundary
convergent boundary
divergent boundary
transform boundary
Mid-ocean ridge and sea-floor spreading happen at this plate boundary
convergent boundary
transform boundary
divergent boundary
Molten rock that erupts form volcanos
hot rock
lava
fraggle rock
magma
A vent at the earth's surface through which magma and gases erupt
volcano
black hole
head
mouth
The zone of earthquakes and volcanoes surrounding the Pacific Ocean.
Three Ring Circus
Ring of Fire
Devil's Rim
Round House of Horror
Tectonic plates are made of?
The mantle
Continental and oceanic lithosphere
The outer core
The mesosphere
How far do tectonic plates move each year?
Meters per year
Centimeters per year
Kilometers per year
Feet per year
