LEARNING TARGET: I will understand and be able to identify different types of weathering.
VOCABULARY (We will do vocabulary boxes for each word.)
- sediment-solid material that is moved and deposited in a new location.
- sediment examples– Rocks, minerals, the remains of plants and animals. May be as small as a grain of sand or as large as a boulder.
- landform-A natural feature on the Earth’s surface.
- landform examples-Four major types: mountains, hills, plateaus, and plains. Minor include: buttes, canyons, valleys, basins, deltas and many, many others.
- weathering– The breaking down of rocks and other materials on the Earth’s surface.
OVERVIEW: Weathering, Erosion, and Deposition
JOURNAL ENTRY: INPUT WEATHERING
- Title and date your page.
- Write the definition of weathering under the title.
- Glue the foldable in your journal so that it may open (see picture below).
- Use the resources below the journal entry description to fill in the information on the types of weathering.
- Open each flap. On the lined journal page, write the name of the type of weathering, the definition and/or description.
- On the opposite side (see image below) find three different types of this kind of weathering and describe how each happens.
- Finally- draw and color one example of each type on the outside of the “flap” as shown above.
THE MAIN TYPES OF WEATHERING: Chemical, Physical, and Biological (Journal page entry)
- BBC Weathering– http://www.bbc.co.uk/bitesize/ks3/science/environment_earth_universe/rock_cycle/revision/6/
- The Geological Society: Weathering- https://www.geolsoc.org.uk/ks3/gsl/education/resources/rockcycle/page3461.html
NOTE: Sometimes weathering is described as MECHANICAL and CHEMICAL.
Weathering can be sorted into three groups: PHYSICAL, CHEMICAL, and BIOLOGICAL. People also sort weathering into two groups: MECHANICAL and CHEMICAL.
What’s the difference?
- MECHANICAL weathering is basically includes all PHYSICAL weathering with BIOLOGICAL actions that break down the earth such as roots growing into rocks and animals burrowing through the ground.
- CHEMICAL weathering includes all of the chemical break down of rocks including acids produced by plants that weaken and break down the rocks and the earth.

HYPOTHESIS– People say that a hypothesis is “an educated guess”. Well, there is NO guessing going on when someone makes a hypothesis. “In science, a hypothesis is an idea or explanation that you then test through study and experimentation.” (vocab.com) Before a scientist makes a hypothesis, they do research, ask questions, and then do more research. It is not just a “guess” that someone then has to prove is true or false.
THEORY– Britannica for Kids describes a scientific theory as, “an explanation for why things work or how things happen. Scientists develop theories based on their observations of the world around them. Theories are based on ideas that can be tested. Theories are not speculative, or based on a guess.”
For an idea to become a theory, there has to be not just one piece of evidence proven to be true or not true, but many pieces. Ideas are tested over and over and over before they become a trusted theory.
