Social Studies Lesson 1 Earth’s Landforms
Do Now Take all the papers out of your red folder. Take them home.
Write a paragraph using the words below. You may not use your book. landforms plate tectonics continental drift fault weathering erosion deposition floodplain delta
word splash A floodplain is plain that has been flooded. A landform is land that is in a different form. A delta is a narrow stream. Erosion is when a river slower wears down a landform.
Essential Question • How do forces of the Earth cause geographic changes?
Assignment: Define the vocabulary for homework. • ..\..\Social Studies\Chapter 1\Chapter 1lfs\Chapter 1 Lesson 1\graphic organizer vocab.doc
How do forces of the earth cause geographic changes? • Turn to page 20-23 in your textbook. • ..\..\..\Social Studies\Chapter 1\continents adrift.asx
Summarization Activity • Write 5 facts (sentences) from the video about forces that change the Earth on the note card. • Collecting note card at 12:16 for a grade.
Do Now • Add to your do now from yesterday. • Write a paragraph using the words below. landforms plate tectonics continental drift fault weathering erosion deposition floodplain delta
A.Plate TectonicsThe theory that earth’s surface is divided into several major, slow-moving plates or pieces. 1. Layers of the Earth • Crust • Mantle • Outer Core • Inner Core 2. Pangaea • The name given to Earth’s landmasses when it formed one huge supercontinent. 3. Continental Drift Theory • Forces within earth caused Pangaea to break apart into continental plates and drift apart. 4. Mountain formation • tectonic plates push together • two plates collide and one moves up over the other
B. Earthquakes • Plates shake causing an earthquake • A fault is a break in Earth’s crust where movement occurs.
C. Volcanoes • Plates push against each other creating cracks in the crust onto Earth’s surface. • Heat within the mantle causes rock in the lower plate to melt. This molten rock is magma. • Lava is the name for magma that has escaped onto the surface.
Do Now Read page 23-24 Shaping Earth’s Surface silently.
