Plate Tectonics How Land Moves and Builds

Group Reading Anytime you see a word or phrase that Is colored your seating group’s color, Read aloud with your group.RedBlueYellowGreenOrange

Lesson Goal I will explain plate tectonic theory including uplift, volcanoes and earthquakes. I will demonstrate knowledge in my science notebook with definitions, illustrations, and question responses.

Our Changing Earth So far, we have learned some ways the Earth changes naturally:Weathering Water Erosion Wind Erosion Extreme Weather

Our Changing Earth This week, we will learn another way the Earth changes naturally: Plate Tectonics Let’s add this topic to our notebook (Don’t forget the Table of Contents)

Plate Tectonics Write Vocabulary under the title Plate Tectonics, where we will be adding some new words as go Let’s start with some new science words to add to our notebook:

Core: the solid rock, very hot center of the Earth

Mantle: the layer of hot rock beneath Earth’s surface

Crust: the outside, hard layer of the Earth

Diagram Draw the diagram in your notebook. Be sure to label the parts we learned.

Inside the Earth 1

Inside the Earth 2

Inside the Earth Check for Understanding Discuss with your table group On your note card, answer: 1. On which layer does erosion and weathering occur on Earth?

I wonder how Earth’s layers relate to plate tectonics? Notes  Earth’s crust is broken into pieces, which “float” on the mantle layer  These pieces, called plates, are always moving, but very slowly  The plates move apart, collide into one another, and slide against other plates We’re going to need more vocabulary words

Magma: melted rock found between the crust and mantle

Tectonic Plates: massive pieces of rock under the land that fit together like a giant puzzle

Continental Drift: when tectonic plates move, causing Earth’s continents to move with them

Plate Tectonics

Continental Drift Check for Understanding Discuss with your table group On your note card, answer: 2. What was Pangea?

Continental Drift Check for Understanding Discuss with your table group On your note card, answer: 3. What caused Pangea to break apart?

I wonder why this is important to Earth’s surface? Notes  When tectonic plates collide, it creates mountains and volcanoes  When tectonic plates move apart, ocean valleys are made  When tectonic plates slide against each other, earthquakes happen We’re going to need more vocabulary words

Fault: the place where two plates touch

Uplift: when plates collide and one is pushed upward, creating a mountain

Folding: when a plate is squished between other plates and pushes up to form a mountain

Mountains

Inside the Earth Check for Understanding Discuss with your table group On your note card, answer: 4. Name two ways mountains are created with plate tectonics

Lava: when magma reaches the Earth’s surface

Volcano: a mountain formed by cooled lava from Earth’s mantle

Volcanoes

Diagram Draw the diagram in your notebook. Be sure to label the parts.

Earthquake: when energy in the Earth causes plates to shift quickly

Epicenter: the place where an earthquake began

Magnitude: how powerful an earthquake is

Earthquakes

Plate Tectonics Check for Understanding Discuss with your table group On your note card, answer: 5. Name 3 ways plate tectonics creates landforms on Earth.

Magic School Bus - Volcanoes

Tsunami: A huge wave caused by an underwater earthquake or volcano

Tsunamis

Volcanic Island: An island created by the continual eruption of a volcano

Volcanic Islands

Types of Volcanoes
