How far down are hot spots?
Hot spots are 30km below crust in the mantle.
They are also 10km
under the ocean.
Scientists create new hypotheses
to study the features and movements of the Earth's surface layer.
How do they affect us today?
Also help us prepare for future disasters.
What is a magnetometer?
Scientists use a magnetometer to measure
magnetic field strength.
Scientists use magnetic data to figure out the age and thickness of volcanic lava flows at ocean island hot spots.

Also on land a magnetometers can be used to find iron ore deposits for mining.
Hotspots under oceanic plates can also form island arcs.


They may be on, near to, or far from tectonic plate boundaries.
