Introduction to the Lithosphere

Introduction to the Lithosphere

Plate Tectonics and Topography

I can describe how and why someone might need to use a topographic map.

Learning Target

8.9 C Earth and Space

The student knows that natural events can impact Earth systems. The student is expected to interpret topographic maps and satellite views to identify land and erosion features...

TEKS

Plate Tectonics

a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle

- Dictionary.com

Topography

the arrangement of the natural and artificial physical features of an area - Dictionary.com

There are consequences related to the movement of plates and the resulting change in the land that affects urban development and development of infrastructure.

Statement of Inquiry

Plate Tectonics

Looking at this picture, what do you think/know about plate tectonics?

This is a topographic map of Mt. Rainier... What's different?

The Earth is dynamic, meaning always changing. It goes through processes like the movement of tectonic plates and as those plates move it causes things like volcanoes, mountains, valleys, islands, and other formations.

Grandpa Diehl was an engineer and explorer

• Climbed several of the highest peaks in the world

• Was a member of the Mountaineers

• Used topographic maps during all of his adventures

• Helped redesign the Panama Canal

• Lived in Alaska and used his map skills there
