1. Constructive & Destructive Forces
S5E1.
Students will identify surface features of
the Earth caused by constructive and
destructive processes.
a. Identify surface features caused by constructive processes.
• Deposition (Deltas, sand dunes, etc.)
• Earthquakes
• Volcanoes
• Faults

2. Study on Quizlet!

4. Earth’s crust is forever changing
Earth’s crust is forever changing. The continents and ocean floors are part of Earth’s crust, which is broken into big pieces called tectonic plates. The tectonic plates float and move on top of the mantle.

5. The mantle contains soft areas where plates float.

6. Plates float on the mantle. The mantle is a made of soft melted rock
Plates float on the mantle. The mantle is a made of soft melted rock. A good example would be like Gelatin.

7. Plates Move 3 Ways

8. Copy these definitions in your flipbook.

9. Constructive forces Construct means to build up.
Forces that build up features on the surface of the Earth.
Sediment (Deltas, sand dunes, etc.)
Volcanoes (makes Islands)
Tectonic Plates (Mountains)
Crust deformation (Folding or Faulting)
Constructive forces

10. Destructive Forces are natural forces that break down the earth.
Water, ice, wind, etc. lead to erosion and weathering of rocks and other landforms over time.
Sometimes, the effects of destructive forces are noticed immediately. After violent actions of volcanic eruptions, earthquakes, floods, tsunamis, etc.,
One can immediately notice changes in the earth's surface features. However, certain subtle processes like weathering change the earth's surface slowly.
