Rocks and Weathering

Plate tectonics >:>

What are the 3 types of convergent plate boundary

O-C, O-O, C-C

What landforms occur at an O-C convergent boundary (destructive)

Composite volcanoes and fold mountains

What landforms occur at O-O convergent boundaries

Island arcs and deep ocean trenches, with underwater volcanoes

What is the deepest ocean trench in the world

The Mariana Trench is the deepest trench in the world, reaching depths of approximately 36,000 feet.

What is decompression melting

Originally, when pressure on a rock is high, it doesn’t melt, even though it could at that temperature. But, when the pressure drops, this rock melts, producing basaltic magma.

What landforms occur at O-O divergent

Mid-ocean ridges, volcanoes and rift valleys
