1
Why is it that the continents or the continental crust at a higher elevation than the oceanic floor?
Continental crust is more dense than oceanic crust
Continental Crust is less dense than oceanic crust
The continental crust covers less surface than the oceanic crust
2
The inner core is composed of solid metal iron and nickel and is the most dense because of pressure from the layers
True
False
3
The outer core is
the thickest layer and made up of solid rock and molten rock
liquid metal iron and nickel and is less dense so it floats
Solid metal iron and nickel because it is more dense due to pressure
4
Which theory came out from the continental drift theory?
Alphabet Theory
Platonic Theory
Tectonic Plates Theory

Look at the photo and tell me which number the INNER CORE is...

6
The crust is the thinnest layer or structure.
False
True
7
Who is the person that came up with the Continental Drift theory?
Alfredo Pasta
Alfonso Benson
Alfred Wegener
8
The deeper you go into the Earth's layers, the more pressure and hotter the temperature
True
False
9
The mantle is...
located at the center of earth and is the hottest
the thinnest layer and it is where the liquid metal is located.
where the convection currents occur and it is the thickest part
10
Which layer has the highest average temperature?
Inner Core
Crust
Mantle
Outer Core
11
Why is the inner core solid, while the outer core is liquid?
the inner core is made of metal and the outer is not
the inner core is hotter than the outer
the inner core is less dense
the inner core is under more pressure than the outer core.
12
What happens to the density if you were to travel from the crust to the mantle?
the density increases because the deeper you go the heavier the layers
the density decreases the deeper you go.
nothing happens because density is the same.
13
Where are tectonic plates located?
Tectonic plates are the closest part of earth to the center of the earth.
They are located underneath the earths crust
Tectonic plates are located in the mantle of the earth
They are pieces of Earth's crust and uppermost mantle, the lithosphere
14
What is the relationship between the inner core and the outer core?
the less dense liquid inner core is suspended in the solid outer core
the two cores are separated by the mantle
the two cores are separated by the crust
the more dense solid inner core is suspended in the liquid outer core
15
What are the 2 different types of Crust? Found the 2 types of Crust.
Platonic
Sounder
Oceanic
Continental
