A convergent boundary is where two plates come together, or converge. The result of the plates hitting together is called a collision.
![Page 18: Tuesday, October 23 rd](https://reader035.fdocuments.in/reader035/viewer/2022062305/5681611c550346895dd0760f/html5/thumbnails/18.jpg)

The process by which the
ocean floor sinks beneath a deep-ocean
trench and back into the
mantle is called

Why Does the Oceanic Crust sink below the Continental Crust?
Oceanic crust is MORE
DENSE than Continental!
![Page 28: Tuesday, October 23 rd](https://reader035.fdocuments.in/reader035/viewer/2022062305/5681611c550346895dd0760f/html5/thumbnails/28.jpg)
• Because one plate gets pushed under another, it is
called subduction. • This is where volcanoes and
trenches form!

Volcanoes form
where a convergen

occurs between oceanic
crust and continenta
l crust.

Volcanoes also form where a convergent boundary occurs between oceanic crust and
oceanic crust.

Aleutian islands of Alaska are volcanoes formed by oceanic crust converging with oceanic
crust

Following volcanic islands in the Pacific Ocean can show us where oceanic crust is
being subducted by oceanic crust.

The place where two plates move apart or diverge is called a divergent boundary.
![Page 40: Tuesday, October 23 rd](https://reader035.fdocuments.in/reader035/viewer/2022062305/5681611c550346895dd0760f/html5/thumbnails/40.jpg)
#1 Sea floor spreading
Can you explain this diagram!?

What causes sea floor spreading?
![Page 42: Tuesday, October 23 rd](https://reader035.fdocuments.in/reader035/viewer/2022062305/5681611c550346895dd0760f/html5/thumbnails/42.jpg)
This is a model of sea floor spreading at a divergent boundary is called a
mid ocean ridge.

Did you know that the Earth’s longest mountain range is underwater and is called the mid-ocean ridge?
: www.ocean.udel.edu
The Mid-Ocean Ridge system, shown above snaking its way between the continents, is more than 56,000 kilometers (35,000 mi)
long. It circles the earth like the stitching on a baseball!

A transform boundary is a place where two plates slip past each other, moving in opposite directions.
