100
Core
Which part of the Earth is the hottest?
200
Converging
Volcanoes occur at what type of boundary?
200
Transform Boundary
What type of plate boundary is found where earthquakes happen?
200
pieces of Earth's crust that float on molten rock
What are tectonic plates?
200
Characteristics of the mantle
Mantle: contains most of Earth's mass very hot, under lot of pressure magma from the mantle flows out of active volcanoes

Epicente
What is the name for the point where the Earthquake reaches Earth's surface called?
300
Mountains and ocean trenches
What can converging plates help form?
400
Mountains and island are formed.
How are volcanoes a "constructive" force?
400
seismic waves
What is the energy that is released when "jerk" apart and create an earthquake called.
400
Divergent boundary
What type of boundary has plates spreading apart?

Molten rock inside the Earth is called magma. When a volcano erupts, lava is released.
When does "magma" become lava?
