What is a continent?
Continents are large continuous landmasses.
What is a sea?
A large body of water (though not as big as an ocean) partially surrounded by land, separating the land and the ocean.
What is an ocean?
A large body of open water.
What is the difference between a sea and an ocean?
A sea is smaller than an ocean and is partially surrounded by land whereas an ocean is a massive open body of water.
What is the largest continent?
Asia.

Asia, Africa, North America, South America, Antarctica, Europe and Oceania.
What are the five oceans?
Pacific, Atlantic, Southern, Indian and Arctic.
What is the largest ocean?

What direction do lines of latitude go in?
They are horizontal (flat).
What direction do lines of longitude go in?
They are vertical.
What are the three main lines of latitude?
The equator, Tropic of Cancer and Tropic of Capricorn.
What are the two main lines of longitude?
The Greenwich meridian and the international date line.
What are the other names for the international date line?
The anti-meridian or the 180º meridian.
Why are lines of latitude and longitude important?
Because they can pinpoint an exact location for any place in the world.
What are lines of latitude and longitude measured in?
Degrees.

Who invented the theory of continental drift?
Alfred Wegener.
What did Alfred Wegener do for a job?
He was a meteorologist.
What does a meteorologist study?
(DON’T BE TRICKED)
Weather.
What sort of person is a geologist?
Someone who studies rocks and land.
What was the main point of continental drift?
That the continents move and separate over time.
What did Wegener name the super continent?
Pangea
What are the two types of crust?
Continental crust and oceanic crust.
What is continental crust made from?
Granite
What is Oceanic crust made from?
Basalt
Which type of crust is heavier?
Oceanic crust
Which type of crust is thicker?
Continental crust
Which type of crust is lighter?
Continental crust
Which kind of crust is thinner?
Oceanic crust
How long ago was pangea formed?
240million-250million years ago
What was one piece of evidence that supported Wegener’s idea?
The fact that the same types of fossil species were found in completely different continents.
Did people believe Wegener?
No, most people and geologists didn’t. Actually though, some biologists supported his theory because it made sense of the evidence they had found over the years on fossils.
What are convection currents?
The process that allows the continents to move.
What is the first step for convection currents?
The Earth’s hot core heats the magma in the mantle around it.
What is the second step to convection currents?
The heated magma is less dense so it rises through the mantle.
What is the 3rd step to convection currents?
As it reaches the bottom of the plates the magma spreads out under the plates, dragging them apart.
What is the 4th step to convection currents?
Where two convection currents are sinking, the plates will be pulled together.
What is the 5th step to convection currents?
The magma cools and becomes more dense so sinks back towards the core.
How many layers make up the Earth’s structure
4
What is the innermost layer of the Earth called?
Inner core
What is the name of the layer in which the Earth’s granite layer is found?
Crust
