10.15.13 Weathering Word Wall

Which of the examples would require the least amount of force to move the box from point A to point B? Explain you answer.

We will learn vocabulary on the effects of weathering, erosion, and deposition by creating a word wall word.

S

Example C because the distance traveled is

greater and the angle of the ramp is lower.

P-

• 7.8 Earth and space. The student knows that natural events and human activity can impact Earth systems. The student is expected to:

• (A) predict and describe how different types of catastrophic events impact ecosystems such as floods, hurricanes, or tornadoes;

• (B) analyze the effects of weathering, erosion, and deposition on the environment in ecoregions of Texas; and

• (C) model the effects of human activity on groundwater and surface water in a watershed.

1. What is a catastrophic event?2. What is a ecoregion?3. What is a watershed?

A- Copy the Vocabulary from Vocab-u-los on EDU “slow changes in an ecosystem”

Abrasion Erosion Mechanical weathering

Creep Deflation DeltaDeposition Erosion Chemical

C- What is the difference between physical weathering and chemical weathering

Create a word wall word: Front: Picture and wordBack: definition, a sentence using two of the vocabulary words, your name and class period

E- Draw each picture and explain which vocabulary words they represent.
