Introduction
Hello students and welcome to the erosion and weathering learning section!
Today in this section,we will be learning about the process for both erosion and weathering. We will learn what is it that causes for these to turn into what they do.
For all of you to get a brief idea of what these topics are going to be about, I will give a brief description of these two. Erosion can be described as happening when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. On the other hand weathering is the wearing away or change of a appearance on a rock.
You ready to learn more about this interesting geologic phenomenon? Just continue to the Task section to learn more!
Task
Tasks:
The goals of this Web Quest include:
- Understanding weathering and erosion.
- Being able to identify different types of erosion and weathering.
The tasks involved:
- Reading thoroughly through the Web Quest to learn about weathering and erosion.
- Finding the answers to the questions in the Process tab.
Weathering and erosion are in your everyday lives! It is happening right in front of your eyes and you might not even be aware of it!
Process
About the Weathering and Erosion Process: Weathering and Erosion work together to change the environment. It is a natural way for larger things get broken down into smaller things. For example, when mountains become hills or when boulders become sand.
Weathering can happen when a rock is dissolved, broken down, or worn away and turned into smaller pieces called sediment. There is no movement in weathering. It can happen for three different reasons: plants and animals, strong weather, or chemical changes in the earth or air.
Erosion can happen when rocks and sediments are picked up and moved to another place by ice, water, wind, or gravity. Erosion is what moves the tiny rocks and soil that weathering leaves behind.
In this section you will need to click on the hyperlink and answer the questions below. You will only have 20 minutes to answer the questions. Your teacher will set a timer. Ready? Set. GO!

Students will need to read through the website to find the answers to the questions. Each question is worth 5 points for a total of 25 points. Students will receive 2 points for incorrect answers. Each student should work alone and answer each question on a separate sheet of paper. Please answer the questions in complete sentences.
1. What are the three kinds of weathering processes?
2. What does mechanical weathering do to rocks?
3. In what four ways can rocks and sediments be transferred from one place to another during the erosion process?
4. What does chemical weather do to rocks and minerals?
5. How does organic weathering happen?
Be sure to check your answers! Once you have finished answering the questions please move on to the Evaluation link to score yourself. GOOD LUCK!!

Ok kids, lets see how much you've learned!!
(use the answer key below to grade your paper)
Answer Key:
(remember each correct answer is worth 5 points and you will only receive 2 points for each incorrect answer)
1. The three type of weathering processes are Organic, Mechanical, and Chemical.
2. Mechanical weathering Physically breaks up rock.
3. Erosion happens when rocks or sediments are picked up and moved to another place by ice, water, wind or gravity.
4. Chemical weathering decomposes or decays rocks and minerals.
5. Organic weathering happens when plants break up rocks with their growing roots or plant acids help dissolve rock.
Congratulations on completing this section of the webquest! I hope you have enjoyed your journey though the weathering and erosion process thus far!
Conclusion
HELLO MY FELLOW 3RD GRADERS!!
As we come to an end to our Weathering and Erosion journey...
I would like to say CONGRATS on completing this amazing expedition through rocks, wind, and so much more!!!!
What have we learned through this AWESOME process???
Well first of all we know that...
WAK!!!!!
WOAH, wind and water just smacked rock right into the face!!!
Well there ya go, we know that WEATHERING is the process of breaking large rocks into smaller rocks over time, by wind and water. And that the EROSION is the movement of weathered rock and soil from one place to another!!
We have learned sooo much through this WEATHERful journey and I'm extremely happy to say that YOU kids are now AWESOME learners and gatherers!
LETS GIVE A VIRTUAL ROUND OF APPLAUSE TO OUR FELLOW THIRD GRADERS!!
