1 STAAR Review – Day 8 Air & Water Currents Weather Plate Tectonics
Topographic Maps Weathering & Erosion

2 Atmosphere Weather and air currents, that affect us, occur in the Troposphere.

3 Air Currents – caused by the uneven heating of the air above land and sea.

4 Air Currents at different latitudes.

5 Ocean currents (gyres) – caused by the sun heating/creating movement of water.
Warms and rises at equator and cools and sinks at the poles.

6 Weather maps Most weather systems start on the West Coast and move to the East Coast.

7 Plate Tectonics Divergent boundaries – plates pull apart and create mid ocean ridges or rift valleys.

8 Plate Tectonics Convergent Boundary: Plates push Into each other -
Creating mountains.

9 Plate Tectonics Transform boundaries – plates slide past each other creating earthquakes and land movement.

10 Topographic Maps This is what a real Topographic map
Looks like. The dark Lines are the contour Index lines with Elevation marked on Them.

11 Topographic Maps – show 3D elevation in a 2D format.
