which term best describes the ability a soil has to support plant growth?
FERTILITY
granite has only recently been exposed at a location on the earths surface how will this most likely affect the soil that will eventually form at this location
The Soil will contain many of the same minerals as the granite has
how does an alluvial fan form?
IT FORMS WHERE A STREAM REACHES A FLAT OVERLAND SLOWS DOWN AND DEPOSITS SEDIMIENT OVER TIME
canyons, caverns, channels and valleys all form because of erosion by water, which landform manly formed because of erosion of ground water
AN UNDERWATER CAVERN
List an example of the abrasion of rock.
a shape change to exposure to wind.
Landslides,Rockfalls,and creep are examples or erosion and deposition by which erosion agent?
GRAVITY
physical and ------ weathering are 2 processes that result in rocks being broken down into smaller pieces
CHEMICAL
The process by which rocks break down as a result of chemical reactions its called -----------
CHEMICAL WEATHERING
a fan shaped mass of sediment dispositive by a stream into a ocean or lake is called a ---------
DELTA
What is the order of the layers of the geosphere when starting from Earth's center and moving outward.
core, mantle, crust
A glacier is a large mass of moving ice what conditions are necessary for a glacier to form?
The weather must be below freezing more snow must fall the melt
the ------ is the part of the earth where life exists and extends from deep ocean floors up into the lower atmosphere
BIOSPHERE
underground water erodes rock in a underwater cavern and overtime the Cavern roof collapsed this process forms what?
SINKHOLES
A river starts as a steep channel in the mountains, leaves the mountains and enters flatter land then meanders across a plain the ocean which of the following action cause the deposition of sand at a delta
RIVER WATER SLOWING DOWN AS IT ENTERS THE OCEAN
What is the composition of the Earth's atmosphere?
78% Nitrogen 21% oxygen 1% other gases.
plants and ------- are source of humus found in soil
ANIMALS
-------- is the dark organic rich material forms a top layer in soil foil from decayed remains of plants and animals
HUMUS
What can cause granite to break down soil overtime?
RAIN AND WIND
Landslides, rockfalls, and mudslides are responsible for both erosion and deposition. What force is mainly responsible for both erosion and deposition that happens in landslides, rockfalls, and mudslides?
gravity
in places where there is loose sediment and strong wind.the wind can pick up the sediment and carry it when the wind slows,it deposits the sediment,which type of sediment will be dropped first as the wind slows
THE HEAVIST
while walking along the seashore you determine that the shore has been affected by stormy seas and rough waves.what can be observed?
THE BEACH WAS ROCKY
If you use a tray of dirt to model a stream and you pour water at the top of the tray and observed erison what would happen when the slope of the tray increased?
WATER AND THE AMOUNT OF ERISION WILL INCREASE
The rock material deposited by glaciers as they melt and retreat is ----------
glacial drift
