Answer 1

Traces of changes in the Earths magnetic field in the alignment of magnetic minerals in sedimentary and igneous rock

Question 2

What is palaeomagnetism linked too?

Answer 2

Seafloor spreading

Question 3

How does salinity influence water density?

Answer 3

Density increases as salinity increases. When salt dissolves in fresh water, the density of the water increases because the mass of the water increases

Question 4

Answer 4

Describes movement of water within and between oceans

Question 5

What is the circulation in the North Atlantic?

Answer 5
