1 Virtual Field Trip Weathering, Erosion, and Deposition

2 Weathering & Erosion  Over the next two weeks we will be going on a virtual field trip! You will learn about weathering, erosion, and deposition. You will see examples of weathering and erosion, including famous places around the United States! It’s going to be a great trip! Buckle up and come along for the ride! 2

11 Weathering & Erosion 11 Weathering is the breakdown of materials in the Earth’s crust into __________________. Erosion occurs when weathered rock is __________________ away by gravity, water, wind, and __________________. Weathering and erosion work together to change the __________________. Physical weathering can happen because of __________________, __________________, or __________________. Acid rain and rust are examples of __________________ weathering. Erosion moves sediment by __________________, wind, and glaciers.

12 Discuss! 12  How can a river be an example of weathering and erosion?  Do you ever see examples of weathering or erosion around your home or school?

13 Stop #1  Complete your exit ticket for Day 1 of our Virtual Field Trip!  Name 1 thing you learned about weathering, 1 thing you learned about erosion, and 1 question you have about weathering and erosion! 13

14 Review  How are landforms formed?  Do landforms change over time?  Do landforms ever stop changing?  What is weathering?  What is erosion? 14

15 THE BREAK DOWN OF ROCKS INTO SMALLER ROCKS BECAUSE OF THE WEATHER

16 Weathering  Imagine you are holding a handful of sand. Look closely. Each grain is actually a tiny rock. It broke off a much larger rock.  The process of breaking down rock is called weathering. Wind and water can hit rocks, changing their shape or breaking off pieces. Temperature changes can make rocks crack. Ice can form, making cracks grow wider. Rocks can also dissolve or change when water or acids react with the minerals in a rock. 16

19 Investigation Time! 19 Rock... or Sponge???

20 Stop #2  Complete the questions on your Rock...or Sponge??? worksheet.  Make sure to take your time and turn it in when you’re done!  Complete your exit ticket! 20

21 Review  What is weathering?  What causes weathering?  What happens to rock when it is weathered? 21

22 Weathering 22 Let’s take a look at this video to get us ready to learn more about how weathering can change the shape of our land.

23 Weathering 23 Weathering is the process of __________________ rocks down into fragments, and then sediments. Weathering can change the Earth’s __________________ over time. Mechanical weathering breaks down rock without changing their __________________ composition. Examples of mechanical weathering include tree __________________, expanding __________________, bolts of __________________, and crystal formation. Chemical weathering occurs when weathering changes the chemical composition of something.

27 Chemical Weathering 27 Let’s take a look at this video to get us ready to learn more about how chemical weathering can change the shape of our land. acid rain chemical weathering

28 Presidential Weathering  We learned that chemical weathering changes the chemical composition of an object.  Acids can mix with water molecules and when it rains, acid rain falls to the ground causing weathering. 28

29 Presidential Weathering  Problem: How will vinegar (an acid) change a penny?  Write down your HYPOTHESIS in your Science Notebook. 29 ** Remember a HYPOTHESIS is an educated guess!

30 Presidential Weathering  I will show you 4 pennies.  1. Clean, has not been put in vinegar  2. Has been in vinegar 1 day  3. Has been in vinegar 2 days  4. Has been in vinegar 3 days.  On your Presidential Weathering chart, draw the penny and write a description of how it has changed. 30

31 Presidential Weathering  Answer the following questions in your notebook:  How did the penny change?  Why is this an example of chemical weathering? 31

32 Stop #3  Way to go! You made it to Stop #3!  Turn in your notebook and Mechanical Weathering Worksheet.  Tomorrow we will continue our Virtual Field Trip through Weathering and Erosion! 32

33 Review  What is weathering?  What is mechanical weathering?  Can you give an example of mechanical weathering?  What is chemical weathering?  Can you give an example of chemical weathering? 33

34 THE MOVEMENT OF ROCKS AND SAND, WHICH CHANGES THE SHAPE OF THE LAND

35 Erosion 35 Let’s take a look at this video to get us ready to learn more about how erosion can change the shape of our land. Take notes!

36 Erosion 36 Erosion happens when water, wind, waves, or glaciers pick up stuff like __________________ and __________________ from the Earth’s surface and __________________ them around. Plant __________________ hold sand and soil together, but when they are not there, erosion goes __________________! Over millions of years, water can cause deep __________________. Sand is made by the process of __________________ rubbing together and becoming smaller and smaller because of the motion of __________________.

37 carves canyons cuts valleys into the land smoothes rocks and moves them downstream

38 Did you know the Grand Canyon was formed from water erosion? hhttp://

39 blows sand and smoothes rocks can carve arches into rock formations

40 crashes into rocks and carves arches and caves changes beaches pushes sand onto the beach and pulls sand out to the sea

41 flattens the land carves out basins or bowls in the land

42 Let's take a trip around the United States to see the affects of erosion across our country! Let's take a trip around the United States to see the affects of erosion across our country! zations/es1205/es1205page01.cfm
