WEATHERING AND
EROSIONLandforms
Palmer – 5th Grade
LESSON GOAL
I understand, recognize, and explain how weathering and erosion create and change landforms on earth
REVIEWLast lesson, we learned how the earth’s tectonic plates move and create mountains, volcanoes, and earthquakes.
REVIEW
INTRODUCTION
In this lesson, we will learn how land changes and moves and learn some new landforms.

is caused by a large amount
of snow sliding downhill
