1. _____the breaking of minerals unevenly (minerals) 2.. _____ type of mechanical weathering occurs when water contracts and expands in rocks (weathering) 3.. _____process builds up land (erosion and deposition) 4.. _____ extremely slow movement of material downslope (gravity) 5.. _____ What do glaciers create? (glaciers) __

Do Now 1. _____where two plates collide 2. _____forms from high temperature and low pressure 3. _____deepest part of the ocean floor 4. _____ lower mantle 5. _____daily rise and fall of Earth’s oceans

Plate Boundaries Key Questions 1. What are the features at a convergent boundary? 2. What are the features at a divergent boundary? 3. What are the features at a transform boundary?

Convergent Plate Boundary 1.Oceanic-Oceanic 2.Continental- Continental 3.Continental- Oceanic Features: Mountains Trenches Volcanoes

Continental-Oceanic Convergent Boundary More dense Oceanic plate subducts (slides) below the Continental plate. Features: oTrenches oVolcanoes oMountains

Oceanic-Oceanic Convergent Boundary Subduction of the older more dense Oceanic Plate Forms a trench or volcanic islands

Continental-Continental The plates buckle up and forms mountain ranges.

Features of Divergent Boundary: Mid-Ocean Ridge Rift Valleys Volcanoes

Transform Boundaries Earthquakes occur at transform boundaries.
