Changes to the Earth - EDIE ERICKSON

Earths Changes St. Francis de Sales 3rd Grade Mrs. Erickson Introduction Changes to the Earth The

surface of Earth changes in natural ways. Change can be caused by a very slow process or a rapid process.

There is evidence on the surface that these processes have caused a change. How do we know that the Earth has changed? A. B. C. It doesnt change.

You can see the evidence. You cant tell. Youre Correct! Are you ready to learn about some of the slow processes that change our planet? Click here to continue! Sorry! Try Again! Read and listen again and see if you can

figure it out. You can do it! Click here to reread. Click here to try the question again. Slow Processes Weathering Weathering is when rocks are being broken apart.

Little or big cracks in the rock are evidence that weathering is taking place. Slow Processes Glaciers

A glacier is a large sheet of ice or snow that moves slowly over Earth's surface, moving rocks, soil, and Earth materials as it moves Glaciers are made when snow

doesnt melt and builds up over years, it gets so heavy that it eventually starts to move. Slow Processes Erosion Erosion is when Earth materials,

like rock, sand, and soil, are being carried away from their original location. Water and wind are often the causes for erosion. Which slow process involves

breaking rock apart? A. B. C. D. Weathering Glaciers Erosion None of the Above

Youre Correct! Are you ready for another question? Click here to continue! Sorry! Try Again! Read and listen again and see if you can figure it out. You can do it! Click here to reread. Click here to try the question again.

Which of these cause erosion? A. B. C. D. Water Wind Glaciers

All of the Above Youre Correct! Are you ready to learn about some of the rapid processes that change our planet? Click here to continue! Sorry! Try Again! Read and listen again and see if you can figure it out. You can do it!

Click here to reread. Click here to try the question again. Rapid Processes Earthquakes An earthquake is when the surface of the ground shakes and rolls causing

damage to the Earths surface Evidence would be cracks and other openings, and damage to roads and buildings. Rapid Processes

Volcanic Eruptions A volcanic eruption is when lava comes out of the volcano and flows down the side of the volcanic mountain (or is sent up into the air and lands nearby) where it hardens.

The hardened volcanic rock forms new Earth material and often makes the volcanic mountain larger. Rapid Processes Landslides

A landslide is when Earth materials, like rock, sand, and soil, on the side of a slope or cliff drop down to a lower location. Water soaking into the ground

often makes this happen. Which rapid process creates new Earth materials? A. B. C. Earthquakes Volcanic Eruptions

Landslides Youre Correct! Are you ready for your next question? Click here to continue! Sorry! Try Again! Read and listen again and see if you can figure it out. You can do it! Click here to reread.

Click here to try the question again. If you see cracks and openings in the ground as well as damage to roads and buildings, that would be evidence of which rapid process? A. B. C.

Earthquakes Volcanic Eruptions Landslides Youre Correct! Guess what? Sorry! Try Again! Read and listen again and see if you can figure it out. You can do it!
