1. why do tectonic plates move?

Tectonic plates be fit to move because the Earths lithosphere has a higher strength and light density than the underlying asthenosphere. Lateral density variations in the winding-clothes result in convection. Their movement is thought to be dictated by a combination of the motion of seafloor away from the bedspread ridge (due to variations in topography and density of the en glowation that result in differences in gravitational forces) and drag, downward suction, at the subduction zones. A antithetical explanation lies in different forces generated by the rotation of the universe and tidal forces of the Sun and the Moon.

2. What the differences between continental and oceanic cheek?

Continental crust is lighter (less dense) than oceanic crust. Continental crust is granitic. Oceanic crust is basaltic. Oceanic crust subducts under a less dense crust whether its oceanic or continental. Continental crust does not subduct. Oceanic crust is much junior in geologic age than continental crust. Continental crust is on average thicker than oceanic crust.

3. Copy and paste a world map showing the tectonic plates.

a) What plate is the UK on?

The UK is on the Eurasiatic Plate.

b) What plate is Jordan on?

Jordan is on the Eurasian Plate.





c) What plate is the USA on?

The UK is on the North American Plate.

d) Why are the UK and USA getting further asunder?

They are moving further apart because of their different slipway of moving plates since they have different densities.

e) take a crap two plates that are moving towards each other.

The Nazca Plate and the South American Plate.

f) Name two plates that are skid past each other.
 
The peaceable plate and North American Plate are sliding pass by each other.

4. Research evidence to try on that Africa and the Americas were once touching?

Continental drift. As...If you want to get a full essay, order it on our website: Orderessay
