Vocabulary
Define the following: Mountain, Lake, Cavern
Mountain - a rocky highland
Lake - a body of water surrounded by land
Cavern - a large underground space
This landform helps erodes materials with streaming water. Deltas are often formed at the end of them
Rivers
Acid rain is a form of pollution that can break apart rocks and buildings. What process is this?
Chemical Weathering
Name two landforms made from weathering
Caverns & Sinkholes
What is the main difference between investigation and experiment?
Experiments have the entire scientific method with variables, while investigations are not the entire method and have no variables.
What's the difference between chemical and physical weathering? What's an example of each?
Chemical weathering is the breaking down of a substance with a chemical that results in something new being formed. Examples include rust and acid rain.
Physical Weathering is the breaking down of a substance that physically breaks it. Examples include water freezing then thawing, cracking a rock and a plant growing through stone. breaking it.
What landform borders all peninsulas?
coastline
Flood waters moving soil from location to another
Erosion - moving of sediments
Name two landforms that help erosion
Rivers & Glaciers
9. Which of these investigations is most likely an experiment? (6.N.1.3)
A. testing how far a marble will roll depending on ramp height
B. using a hand lens to examine four different rocks
C. measuring the width of a desk with a meter stick
D. observing cells under a microscope
A. testing how far a marble will roll depending on ramp height
What is erosion? What is deposition? Name an example of each.
Erosion - Moving of Sediments
Examples: Landslides, glaciers carrying pebbles, wind carrying sand
Deposition - Dropping of Sediments
Examples: Rivers dropping off sediments in deltas, wind dropping off sand in dunes.
This landform is often found on beaches and keep their form due to the beach grass around them
dunes
Marsha places a sealed plastic bottle of water in a freezer. The next day she discovers that the water has frozen and split the sides of the bottle. Is this Chemical Weathering, Physical Weathering, Erosion, or Deposition?
Physical Weathering
What are two landforms formed by deposition?
Delta & Dune
Mason is writing down all the different types of plants he can find in his backyard. Is this an investigation or experiment? If this is an experiment, what are the independent and dependent variables? How do you know?
This is an investigation because he is not testing any variables and not carrying out the scientific method
13. Many parts of Florida are prone to sinkholes. Which process causes sinkholes to form? (6.E.6.1)
A. Fast-moving water causes rocks to crumble.
B. Surface water dissolves and weakens rocks.
C. Oxygen reacts with rocks and causes them to rust.
B. Surface water dissolves and weakens rocks.
What two landforms are made by movement and deposition of sand and sediment?
Dunes & Deltas
Dirt settling at the bottom of a river
Deposition
This landform is made when piles of silt form at the mouth of a river opening into the ocean.
Name the landform and the process that made it
Delta -- Deposition
Sadie is testing to see which brand marker lasts the longest. Is this an experiment or an investigation? How do you know? If this is an experiment, what are the independent and dependent variables?
Experiment, it has variables and they're trying to find a cause and effect.
IV - brand of marker
DV- how long the marker lasts
How is a natural sand dune formed? (Be Specific!)
Windblown sand is trapped by beach grass or other objects
This landform is not found in Florida, but helped formed Florida's coastal plains by weathering and eroding the land around it.
Glaciers
Rain fell onto a stone, the water seeping into the cracks. Over night, the water freezes, causing the crack to expand. When the day breaks, the water melts leaving the stone completely broken in half.
What process is this: Chemical Weathering, Physical Weathering, Erosion, or Deposition.
Physical Weathering
This landform is made when acidic rainwater dissolves away underground limestone, forming holds in the ground.
Name the landform AND the process that made it
Sinkholes - Chemical Weathering
Megan loves bird watching, but she knows just making observations about the birds she sees would be an investigation. Design an experiment Megan can conduct with her love of bird watching. Make sure to identify independent, dependent, and control variables.
(Answers vary) Megan can see what type of feed the birds prefer.
IV - Change the feed, DV- Count how many birds visit each feeder, CV - length of time to collect data
