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
3
Multiple Choice
Would plants growing throughout the ground cause mechanical or chemical weathering?
Mechanical Weathering
Chemical Weathering
4
Multiple Choice
Is rusting occur due to chemical or mechanical weathering?
Mechanical Weathering
Chemical Weathering
5
Multiple Choice
Sand arches are created in the desert by wind action.
Mechanical Weathering
Chemical Weathering
6
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
7
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
8
Categorize
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
9
Multiple Choice
Rocks are smoothed over by the constant motion of a fast moving river. What is this an example of?
weathering
erosion
deposition
10
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.
11
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!
12
Open Ended
What is an aquifer?
13
Multiple Choice
which of the following landforms is a result of the chemical weathering of carbonate rock?
dunes
rivers
sinkholes
mountains
14
Open Ended
Why do rivers move slow in Florida?
15
Open Ended
How was the Grand Canyon formed?
16
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)
17
Labeling
Label the parts of the rock cycle
cooling
heat and pressure
weathering and erosion
lava
sediments
igneous rock
metamorphic rock
sedimentary rock
18
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
19
Multiple Choice

Multiple Choice
Select the letter the shows where you would find SEDIMENTARY ROCKS
A

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
23
Open Ended
Why is it important to replicate experiments?
24
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
25
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?
