The [blank_start]descending[blank_end] plate pulls [blank_start]the edge of the continental plate[blank_end] creating [blank_start]deep ocean trenches.[blank_end] Then the continental plate is [blank_start]lifted[blank_end] and [blank_start]a mountain chain develops[blank_end] on the [blank_start]overriding[blank_end] continental plate. The oceanic crush then [blank_start]melts into the earth[blank_end] and [blank_start]few molten rocks[blank_end] rises through the [blank_start]cracks[blank_end] in the crust to [blank_start]form volcanoes.[blank_end]

37. 37Describe the three different types of weathering processes and give an example of each.
    
    [blank_start]Chemical weathering[blank_end] is the [blank_start]chemical change of the minerals in the[blank_end] rock. [blank_start]Metamorphic chemical[blank_end] changes are usually mistaken as [blank_start]chemical weathering[blank_end]. one example of chemical weathering is [blank_start]acid rain[blank_end]; when [blank_start]fossil fuels[blank_end] are [blank_start]burnt[blank_end] they release [blank_start]carbon and nitrogen[blank_end] and [blank_start]with the moisture in the air[blank_end] it produces [blank_start]sulfuric acid[blank_end] and [blank_start]carbonic acid[blank_end], which is why it has [blank_start]more acidity[blank_end] then average rainfalls.
    
    .[blank_start]Mechanical weathering[blank_end] is the [blank_start]physical breakdown[blank_end] of the rocks into [blank_start]smaller fragments[blank_end] without c[blank_start]hanging the chemical composition.[blank_end] One example is [blank_start]Freeze-thaw[blank_end]. When water is [blank_start]leaked into crack[blank_end]s of rocks and it [blank_start]freezes it expands[blank_end] and [blank_start]pushes[blank_end] the rocks [blank_start]apart.[blank_end]
    
    
    [blank_start]Biological weathering[blank_end] may involve [blank_start]bother chemical[blank_end]; [blank_start]production of organic compounds[blank_end] that [blank_start]break down minerals[blank_end] and [blank_start]rocks and physical processes;[blank_end] roots growing into [blank_start]cracks[blank_end]; depending on [blank_start]the processes of the organism[blank_end]. one example is when [blank_start]tiny bacteria, algae[blank_end], [blank_start]moss grow[blank_end] on rocks and produces a [blank_start]chemical break down on the surface[blank_end] of the rock.

38. 38Describe two land form features formed by each other following forces: water, wind, and ice.
    
    [blank_start]Water:[blank_end] At the [blank_start]upper reaches[blank_end] of rivers in the [blank_start]mountains[blank_end], the [blank_start]velocity of a river[blank_end] is high [blank_start]due to gradation changes[blank_end] and [blank_start]erosion is an active[blank_end] process as the river tries to [blank_start]adjust to the topography[blank_end], As a result, large canyons and valleys are [blank_start]often carve out of the mountains[blank_end].
    
    Where there is [blank_start]differential erosion[blank_end] within the ground, water falls [blank_start]are shaped[blank_end] with the [blank_start]erosion[blank_end] of the [blank_start]cliff.[blank_end]
    
    [blank_start]Wind:[blank_end] Deposition of sand [blank_start]occurs as sand sheets[blank_end], which are generally [blank_start]flat rolling area of sand[blank_end], as dunes with gentle [blank_start]upwind slopes[blank_end] and [blank_start]steep leeward slopes to as a slipface[blank_end]. The [blank_start]minimum height[blank_end] of the slipface for the [blank_start]mound[blank_end] to be classified as a dune is [blank_start]30 cam[blank_end]. The [blank_start]sand grains[blank_end] move up the slope by [blank_start]saltation and creep[blank_end], the particles accumulate at the [blank_start]top[blank_end], and when the [blank_start]angle of repose[blank_end] is exceeded they fall over in a tiny landslid. As this process continues the dune moves in the [blank_start]direction of the wind.[blank_end]
    
    Most of the [blank_start]dust[blank_end] carries by [blank_start]dust storms[blank_end] is in the form of [blank_start]slit-size particle[blank_end]s, and the [blank_start]deposits of windblown silt[blank_end] are called [blank_start]loess[blank_end].
    
    [blank_start]Yardangs;[blank_end] sculpted land forms; are up to [blank_start]tens of meters high[blank_end] and [blank_start]kilometers long[blank_end] and have been [blank_start]streamlines by the erosion[blank_end] due to the [blank_start]desert wind.[blank_end]
    
    
    [blank_start]Ice/Glaciers:[blank_end] [blank_start]Cirques[blank_end] are horseshoe shaped [blank_start]depressions[blank_end] formed by the [blank_start]erosional action of alpine glaciers[blank_end]. [blank_start]Moraine[blank_end] are glacial rocks that are deposited along [blank_start]the edges of the glaciers.[blank_end] [blank_start]Kettles are large chunks[blank_end] of ice left in a depression [blank_start]melt to form small rounded lakes.[blank_end] [blank_start]Kames[blank_end] are [blank_start]ponds[blank_end] or depressions left by [blank_start]melting masses of glacial ice.[blank_end]
