Weathering, Erosion & Deposition
Water, wind, ice and gravity are forms of physical weathering, unlike _______ and ______which are forms of chemical weathering.
What is ACID RAIN, ACID GROUNDWATER, or LICHEN?
This lake covers over 400,000 acres of area and is the largest lake in Florida.
What is LAKE OKEECHOBEE?
______ create U-shaped valleys while _______ make V-shaped valleys.
What are GLACIERS and RIVERS?
What are chemical and physical weathering?
These large, frozen landforms can be found on every continent, including Africa.
What is a GLACIER?
Decaying leaves affect rocks in the soil below them by releasing acids which could cause this.
What is CHEMICAL WEATHERING?
What is a CAVE?
Wind can erode and deposit this very fine form of sediment.
What is LOESS?
These two formations can be created only by wind.
What are dunes and mushroom rocks?
A ______ is formed by deposited sand in the water near a beach but moves and has little vegetation (plants) growing on it.
What is a SANDBAR?
This is created when a river slows down, depositing sediment as it flows into a large body of water.
What is a DELTA?
When a lake in Florida loses water and becomes shallower, ______ is the most likely reason.
What is LACK OF RAINFALL?
What is a CREEP?
These two living organisms can contribute to physical weathering.
What are plants and animals?
I want to go camping by dunes. These two places are where I can find them.
What are DESERTS and BEACHES.
Rivers deposit sediment past their delta and into the ocean. This reason could explain why a river might drop its sediment in the delta itself.
What is a lack of rain/low water levels?
These landforms are the reason Florida changes size as sea levels go up and down with the world's climate.
What are GLACIERS?
These two landforms are clues that a continental glacier created them.
What are KETTLE LAKES and ERRATICS?
These "-ion" processes are forms of both chemical and physical weathering.
What are OXIDATION and ABRASION?
When a cave collapses forming a sinkhole, ______ will determine whether it can hold water and become a lake.
What is SEDIMENT?
Like a delta, this is formed when a stream carrying sediment slows and weakens, depositing its sediment on land.
What is an ALLUVIAL FAN?
These two animals contribute to physical weathering here on Marco Island.
What are GOPHER TORTOISES and BURROWING OWLS?
Limestone is a very soft rock that reacts easily to acids, while quartz is a very hard mineral that does not. Explain two methods to test which is which using physical and chemical methods.
Many different tests are available, but it's up to Mr. Beck to decide whether you answered right :)
These two properties influence how much erosion the stream makes.
What are SPEED and VOLUME (AMOUNT OF WATER)?
What is DESERT PAVEMENT?
