I'm Also doing my Science homework xD
Plate tectonics can lead to the thinning of plates when they separate at divergent boundaries. As plates move apart, magma rises to fill the gap, creating new crust and causing the existing plates to stretch and thin out. This process is known as seafloor spreading.

Tectonic plates
The Earth's plates are called tectonic plates.
tectonic plates?
quiet ,and explosive eruptions
they are slow eruptions that aren't really violent. Very rarely does a Hawaiian volcano throw out mountains of ash.

The earth's tectonic plates are always moveing. So the movement of the plates creates earthquakes and when they separate lets lava spill out and dry. Scientists can locate these movements over hundreds of years and form kind of like a child's game, connect the dots. But just the ones within about 10 to 20 miles.
really? I would have thought that was relatively obvious. depending what kind of plate boundary you have; subductive, constructive, destructive or conservative, you see different patterns, but generally earthquakes and or volcanoes. tsunami/ tidal waves tend to follow earthquakes and tell tale geological features may be underwater trenches, mountains, volcanoes though many fault lines are invisible. the himalayas are built on a constructive boundary with the burmese and phillipine plates (something like that, anyway, don't quote) hope that's helpful :s xx
