What is Pangaea?
an ice sheet which covered several continents
the fossil of a fern found on different continents
a mountain belt linking two continents
a supercontinent that contained all the continents
Which of the following is evidence that supports continental drift?
Penguins live on Africa and Antarctica
Fossils of the same plant have been found on continents separated by oceans
The presence of glaciers in Antarctica
The coastlines of South America and Africa seem to fit together. This is an example of ____ evidence.
geometric
mountain
rock
algebraic
What evidence supports the idea that all the continents were once joined together? Select all that apply.
Mountains with matching rock patterns on different continents
Seashells found at the bottom of the ocean
Evidence of glaciers found in warm climates
A dinosaur fossil found in Arizona
A slow-moving, plant-eating reptile lived over 250 million years ago. Fossils of this creature (Lystrosaurus) have been found in the brown areas of the picture. How does this support the existence of Pangaea?
The reptile swam across the ocean from one continent to another
Lystrosaurus drifted on rafts of vegetation from one place to another
Africa, Antarctica, and India used to be joined together in one big landmass
True or False:
The hypothesis of continental drift was accepted and believed in 1912.
True
False
Who was the German scientist who proposed the theory of continental drift?
Bill Nye
Dr. Diggs
Alfred Wegener
Friedrich Mohs
When Wegener looked at maps he noticed African and South America ____________ lined up.
lakes
islands
rivers
mountain ranges
What is the type of heat transfer that occurs in the mantle?
Conduction
Convection
Radiation
Friction
What does the theory of continental drift state?
The continents were once joined in a super-continent and have moved over time
Erosion moves continents from one location and deposits them in another
The Earth is broken into pieces that move due to convection currents
lava is rebuilding the ocean floor over long periods of time
The scientist who came up with the idea that land was once all connected was missing something very important. What was it?
He could not explain HOW the continents moved
He didn't have any evidence
His data was wrong
He didn't use the right technology to gather data
What are the two types of crust?
continental and oceanic
ocean and basin
lower and upper
thick and thin
Which layer is made (mostly) of SOLID iron?
crust
mantle
outer core
inner core
What is the relationship between temperature and pressure compared to the depth of Earth's layers?
temperature and pressure decrease as you go towards the core
Temperature increases by pressure decreases as you go towards the core.
Nothing, temperature and pressure stay the same as you get closer to the core.
Temperature and pressure increase as you go towards the core.
The movement of this liquid layer gives us Earth's magnetic field.
mantle
atmosphere
inner core
outer core
