Catalyst
If you took the quiz: Define the following in
your Catalyst Section of your Class Journal:▪ Weathering▪ Weather▪ Rill erosion▪ Gully erosion▪ Respiration*▪ (Not in your books – think
back to biology)
You may use the books to complete this Catalyst.

Agenda
Catalyst (5 mins) Announcements (3 mins) Opening (2 mins) Re-teaching: Chapter 7 (10 mins) Mini Quiz (15 mins) Independent Work: Section 9.1 (20 mins) Mini-Lesson: Surface Water Movement (15
By the end of class, CWBAT review the most challenging sections of Chapter 7, will be able to define the vocabulary and concepts for Section 9.1, and will complete a complex modeling activity about bed loads.
CCSS Literacy: 4. ▪ Determine the meaning of symbols, key terms, and other
domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 11–12 texts and topics.
CRS EMI.603▪ Use new information to make a prediction based on a model
Re-teaching: Chapter 7
Notes
Use the Guided Notes handout
Definitions
Weathering Chemical or
mechanical processes that break down or change rocks/minerals on or near the Earth’s surface
Weather Current state of the
atmosphere, including short-term variations such as temperature and precipitation
Weathering ≠ Weather Humans can impact weathering AND
climate, but climate change was not covered in Chapter 7
Definitions
Rill erosion Erosion in which
water running down the side of a slope carves a small stream channel.
Gully erosion Erosion that occurs
when a rill channel widens and deepens.
More destructive than rill erosion.
Definitions
Respiration The process in
living organisms of taking in oxygen from the surroundings and giving out carbon dioxide
Breathing
Respiration and Weathering? Contributes to
chemical weathering Carbon dioxide
combines with atmospheric water to make weak carbonic acid Can react with the
calcite in limestone and marble▪ Damages such materials
Can also form clay minerals

The Easiest Quiz Ever!
Pre-test for our unit on Freshwater Systems 6 fill-in-the-blanks; 8 short answer You will only be graded on completion.▪ Do NOT put “IDK” for an answer – give it your
best shot. I want to see what you know
Independent Work
SILENTLY Read Section 9.1 (pages 211-221)
Create an outline for this section Include:▪ Section headings/subheadings▪ Vocabulary terms and definitions▪ Key concepts
20 minutes If you finish early, repeat the above
steps for Section 9.2 (pages 222-227)
Surface Water Movements
The Water Cycle
Only give an answer if you are the one holding the Nubbly Ball!
The Water Cycle
Transpiration
Infiltration
Runoff
Water which flows downslope along Earth’s surface
Runoff may: Reach a stream,
lake, or river Evaporate Form puddles and
go through infiltration▪ Soaking into ground
Runoff vs. Infiltration
Several factors:1. Vegetation2. Rate of Precipitation3. Soil Composition4. Slope
1) Vegetation
Soil with more vegetation allows more water to enter the ground.
Why? Less force
The harder rain hits the ground, the more it compacts the soil.
More compact = less pores
Gardening
2) Rate of Precipitation
What type of rain do you think infiltrates dry ground? Light, gentle
precipitation Heavy precipitation
becomes runoff▪ Falling too quickly to
infiltrate
3) Soil Composition
Soil is made of Humus ▪ Decayed organic material▪ Creates pores
Minerals▪ Different sizes: sand, silt, clay
Sand (coarse) = larger pores More infiltration
Clay (fine) = small/no pores
4) Slope
Greater slope = more runoff (less infiltration) Also has greater potential for erosion
Which will have more infiltration?
Which will have more infiltration?
Stream Systems
Made up of streams, tributaries (streams that feed into other streams), and rivers (large streams) Amazon River
system Watershed
All of the land whose water drains into a stream system
Stream Load
All the materials that the water in a stream carries
1. Solution Material is carried in solution after it
becomes dissolved in the stream’s water.
Ex.: soluble minerals from rocks like calcium carbonate from limestone
The Three Ways Streams Carry their Loads
2. Suspension When small particles are held up by the
turbulence of a stream’s moving water Ex.: silt, sand, clay
The Three Ways Streams Carry their Loads
3. Bed Load Larger particles that are pushed/rolled
along the bed of the stream by the moving water
Ex.: sand, pebbles, cobbles
Stream Loads
Table Partner Work
There should not be excessive talking during this time.
With your table partner ONLY, complete the “Problem-Solving Lab” on page 217. #1-4 Due at the end of the period
Closing
Review Objective By the end of class, CWBAT review the
most challenging sections of Chapter 7, will be able to define the vocabulary and concepts for Section 9.1, and will complete a complex modeling activity about bed loads.
