When weathering occurs at mountains, large slabs of rocks detach from it. The rocks would move down and this movement is called mass wasting. What causes this downward motion?
Gravitational force of earth
Rotation of the earth of its axis
Revolution of the earth around the sun
Strong winds on the earth surace
When a river picks up small particles of soil, rocks, and other materials and moves them down the river leaving them miles from where they originated. This is known as____.
Deposition
Volcanic eruption
Continental drift
Tsunamis
Which of the following is an example of chemical weathering?
The dissolving of limestone by acid rain.
A rock broken into chunks after being carried by rapidly flowing water.
Pulverized rock resulting from a landslide.
Splits in a rock due to tree roots.
Caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water.
Chemical Weathering
Mechanical Weathering
Biotic Weathering
Mass Wasting
Occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart. The processes induced by stresses created by the freezing of water into ice.
Freeze-thaw
Block disintegration
Exfoliation
Transportation
Which of the following process does NOT alter the composition of material?
chemical weathering
dissolution
hydrolysis
mechanical weathering
What type of weathering is exhibited when the rocks are fractured, cracked, and broken down into small pieces?
chemical weathering
oxidation
physical weathering
pressure change
Which of the following is an example of oxidation?
rusting of iron
halite dissolves in water
feldspar decomposes to form clay
stalactites and stalagmites formation
Which activity does NOT facilitate erosion?
kaingin
loss of plant cover
planting
steepening of slope
Which diagram exhibits the most ideal arrangement for exogenic processes?
erosion – sediments – weathering – transport- deposition
sediments – erosion – weathering – transport
sediments – transport – erosion – weathering
weathering – erosion – transport-deposition
What term refers to the removal and transport of weathered material from one place to another?
deposition
erosion
sublimation
weathering
Wind blown sand hitting a rock and slowly wearing it away is an example of ___________________.
Chemical Weathering
Chemical Erosion
Mechanical Erosion
Physical Weathering
Occurs as cracks develop parallel to the land surface a consequence of the reduction in pressure during uplift and erosion.
Freeze-thaw
Exfoliation
Block disintegration
Plucking
It refers to the transfer of weathered material to different places.
weathering
erosion
mass wasting
deposition
Which of the following describes the breakdown of rocks due to impact and friction?
Oxidation
Hydrolysis
Frost wedging
Abrasion
The pictures shows a before and after scenario of a marble statue. Marble is known to be a carbonate. The carbonates in the rocks react with water that produces weak acids resulting to the after situation. What kind of weathering happened to the statue?
chemical
mechanical
biological
technical
Chemical weathering is greatest under conditions of
higher rainfall and temperatures.
lower rainfall and temperatures.
higher rainfall, but lower temperatures.
near absence of rainfall, but higher temperatures.
Which of the following does NOT describe the advantage of wind barrier such as row of trees along the edge of field?
conserve moisture
trap the blowing wind
increases the effects of wind erosion
protect crops from the effects of wind
Also known as slope movement or mass movement, is the geomorphic process by which soil, sand, regolith, and rock move downslope typically as a solid, continuous or discontinuous mass, largely under the force of gravity, frequently with characteristics of a flow as in debris flows and mudflows.
Mass wasting
Erosion
Weathering
Exogenic Processess
Which of the following is NOT a role of gravity in erosion?
It moves glaciers down slope
It loosens the land materials.
In mountains, it moves down large slabs of rocks.
It acts as agents of mass wasting like landslides, fall, mudflows, and avalanches.
