Convergent Boundary

Convergent Boundary
Convergent Boundaries are plates coming together. There are three different types of Convergent Boundaries. Ocean-Ocean forms arcs of islands and strato volcanoes. Ocean-Continent forms volcanoes and mountain ranges. Continent-Continent forms huge mountain ranges like the Himalayas in Nepal.

Divergent Boundary

Divergent Boundary
Divergent Boundaries are plates pulling apart. When Plates diverge, the Earth’s crust splits apart causing magma to rise from the mantle, depending if it happens at sea or land, it forms mid-ocean ridges or rift valleys.

Transform Boundary

Transform Boundary
Transform Boundaries are plates sliding past each other. This boundary releases a cause of a violent earthquake. The main types of waves are, P waves, waves that go back and forth. S waves, waves that go up and down and L waves, waves that go in all directions and the most dangerous.

Subduction Zone

Fault and Subduction Zone
A subduction zone is when one plate goes under another. An oceanic plate goes down because is more dense (heavier) and the continental plate goes up because is lighter. This happens because of faults, causing the formation of trenches and volcanoes.

Earthquake

Tsunami

Earthquake and Tsunami
An Earthquake is formed by Transform plate boundary. The earthquake’s first movement happens in the focus and the epicenter is the point on Earth’s surface above the focus and plates move. Earthquakes happen on land. Thrust/Reverse Fault causes an upward wave or a Tsunami. A tsunami is an underwater earthquake, landslide, or a volcanic eruption.

Hot Spot

Hot Spot
Hot Spots are areas of volcanic activity from deep under the Earth’s mantle. An example of a hot spot is Hawaii, an island made up of volcanoes that are no longer active.
