CFA 6
Study Guide

1. Take out your journal

2. Write the heading "CFA 6 Study Guide"

3. Be prepared to take notes

Topic 1: Types of Weathering

• Chemical weathering = changes the chemical make up of rocks

  • occurs faster in warmer, humid climates

  • Example - the statue of liberty turning green, acid rain creating holes in rocks

• Mechanical weathering = changes the way the rock looks

  • Examples of mechanical weathering - a rock is smoothed over by constant wave action

Multiple Choice

Would plants growing throughout the ground cause mechanical or chemical weathering?

• Mechanical Weathering

• Chemical Weathering

Multiple Choice

Is rusting occur due to chemical or mechanical weathering?

• Mechanical Weathering

• Chemical Weathering

Multiple Choice

Sand arches are created in the desert by wind action.

• Mechanical Weathering

• Chemical Weathering

Multiple Select

What determines how fast a rock is broken down by CHEMICAL WEATHERING:

• The age of the rock.

• cooler climates

• 
  The minerals that makeup the rock.

• amount of humidity

• warmer climates

Topic 2: Weathering, Erosion, and Depsotion

• Weathering = breaks rocks

• Erosion = takes rocks away

• Deposition = drops rocks off

Draw the landform on the right and label where weathering, erosion, and deposition take place

Weathering

Erosion

Deposition

Categorize

Options (14)

breaks

takes

drops off

river delta

beach

sand dunes

aquifer

sinkhole

compaction

cementation

water carrying rocks down a river

wind moving sand around to create sand dunes

wind scraping across rocks to make arches

the colorado river smooths the walls of the grand canyon

Organize these options into the right categories

Weathering

Erosion

Deposition

Types of landforms

Multiple Choice

Rocks are smoothed over by the constant motion of a fast moving river. What is this an example of?

• weathering

• erosion

• deposition

Multiple Choice

Which is an example of Erosion?

• Sand being pulled away from a beach by waves.

• 
  Roots of a tree breaking apart a rock

• depositionwater in a river smoothing down rocks.

Topic 3: Landforms in Florida

• Florida is very flat, rivers are shallow and slow

• Florida is built on limestone, which is carved away by chemical weathering

• This creates 2 important landform aquifers

  • aquifers = most of Florida freshwater

  • sinkholes = dangerous!

Open Ended

What is an aquifer?

Multiple Choice

which of the following landforms is a result of the chemical weathering of carbonate rock?

• dunes

• rivers

• sinkholes

• mountains

Open Ended

Why do rivers move slow in Florida?

Open Ended

How was the Grand Canyon formed?

Topic 4: The Rock Cycle

• Metamorphic = heat and pressure underneath the earth

• Igneous = cooling of lava

• Sedimentary = layers of rock, you can see the pieces

• Rocks that are jagged and sharp are younger. Rocks that are smooth are older (more time for weathering)

Labelling

Label the parts of the rock cycle

Drag labels to their correct position on the image

cooling

igneous rock

metamorphic rock

heat and pressure

sediments

weathering and erosion

sedimentary rock

lava

Match

Match the following

• igneous rock

• metamorphic rock

• sedimentary rock

cooling of lava

heat and pressure

compaction of sediments

• cooling of lava

• heat and pressure

• compaction of sediments

Multiple Choice

Select the letter the shows where you would find IGNEOUS ROCKS

• A

• B

• C

Multiple Choice

Select the letter the shows where you would find METAMORPHIC ROCKS

• A

• B

• C

Multiple Choice

Select the letter the shows where you would find SEDIMENTARY ROCKS

• A

• B

• C

Topic 5: Science

• It is important to replicate experiments in order to make sure results are VALID

• You can NEVER change data after completing an experiment

• Collaboration is key = scientists work together

Open Ended

Why is it important to replicate experiments?

Multiple Choice

You can change data in order to make you hypothesis correct. The goal of an experiment is to prove that your hypothesis is always correct.

• TRUE

• FALSE

Open Ended

Two groups of scientist are trying to determine if eating peppermints during a test makes students test scores improve. Group A collects data that is very similar to Group B.

Group A saw students test scores improve by 21%

Group B saw students test scores improve by 25%

The existing theory is that candy does NOT make students smarter. Can you change the existing theory? Why or why not?
