Weathering
What type of weathering occurs when plant roots grow into rock cracks and force them apart?
Physical weathering
What particles are dropped first when sediments are deposited?
The heaviest particles fall first
What landform forms when groundwater dissolves limestone and a cave collapses?
Sinkhole
Why do most rivers in Florida flow slowly?
Because Florida is very flat
A fence on a beach causes sand piles to form behind it. What is forming?
A dune
Which process occurs when water freezes in cracks and widens them over time?
Frost wedging (physical weathering)
Which event causes erosion, not weathering, at a beach during a hurricane?
Sand washed away
What landform forms at the mouth of a river when sediment builds up?
Delta
Double Jeopardy!
How did melting glaciers long ago affect Florida's coastline?
A coastline becomes narrower after several storms. What process is responsible?
Increased erosion
Acid rain describes what kind of weathering?
Chemical weathering
Why does a river deposit sediment at its mouth?
Because the water slows down as it reaches the ocean
Double Jeapordy!
Canyon
Why doesn’t Florida have many deltas?
Rivers are too slow to carry much sediment
A glacier leaves rocks behind after melting. What process is this?
Deposition by ice
Wind blowing sand against rock smooths the rock surface. What process is happening?
Abrasion (a form of mechanical weathering)
A coastline gains sand in one place and loses sand in another. What processes explain this?
Waves erode sand in some areas and deposit it in others
What kind of rivers does Florida have and why?
slow‑moving water due to flat land
What helps shape Florida’s long coastline daily?
Continuous erosion and deposition by waves
Double Jeapordy
A river widens as it moves sediment downstream. Which two processes are involved?
A rock breaks down faster when both chemical and mechanical weathering act on it. Why?
Because both processes weaken the rock at the same time, increasing breakdown rate.
Glaciers change landscapes as they move. Which two processes do they perform?
They weather rocks and erode (carry away) the sediment
What processes most changes the shape of coastlines over time?
Erosion and deposition
What landform is common in Florida due to limestone erosion?
Sinkholes
A hurricane hits a coastline. Which effect is most directly related to erosion?
Sand washed away from the beach by storm surge
