Test 2 Flashcards
What are earthquakes
They are sudden tremors in the earth
What type of plates make earthquakes and explain how
Passive plates. Plates that slide past each other have passive boundaries. Crust is neither created nor destroyed. These plates are locked together and then release a huge amount of energy when they slide past each other. Sliding plates cause earthquakes and fault lines.
What happens when plates pass each other
There’s a built up of pressure on the fault line and when the plates get past each other this energy is released and creates an earthquake
