_______ contain close to 70% of all the fresh water on Earth.
Q. _______ contain close to 70% of all the fresh water on Earth.
Q.. _______ erosion is most common in flat, bare areas with dry, sandy soils.
Deflation, in geology, erosion by the wind of loose material from flat areas of dry, uncemented sediments such as those occurring in deserts, dry lake beds, floodplains, and glacial outwash plains.
Q. The zone of _______ is located below the equilibrium line of a glacier.
Q. Glaciers are most likely to advance during _______ summers.
Q. Wind speed and _______ determine how quickly abrasion will occur.
Q. The Southern Plains region of the United States that experienced a long drought and heavy wind erosion during the 1930s was called the _______.
A. Glaciers
A glacier is a large body of ice and snow. It forms because the snow in an area does not all melt in summer. Each winter, more snow is added. The weight of all the snow creates pressure. This pressure turns the lower parts of the snow into ice. After this happens for many years, the glacier will start growing large. It becomes so heavy that gravity causes the ice to move. It flows downwards like water but very slowly. A glacier only moves about 50 meters (160 ft) per year. New snowfalls replace the parts that flow away.

Glaciers are the largest sources of freshwater on Earth. The largest bodies of saltwater are the Oceans.
Q.. _______ erosion is most common in flat, bare areas with dry, sandy soils.
A. Wind
Wind erosion is a serious environmental problem attracting the attention of many across the globe. It is a common phenomenon occurring mostly in flat, bare areas; dry, sandy soils; or anywhere the soil is loose, dry, and finely granulated. Wind erosion damages land and natural vegetation by removing soil from one place and depositing it in another. It causes soil loss, dryness and deterioration of soil structure, nutrient and productivity losses and air pollution. Suspended dust and dirt is inevitably deposited over everything. It blows on and inside homes, covers roads and highways, and smothers crops. Sediment transport and deposition are significant factors in the geological changes which occur on the land around us and over long periods of time are important in the soil formation process.

The term wind erosion refers to the damage of land as a result of wind removing soil from an area. Most often, wind erosion occurs on flat land in dry or sandy areas.
Q. Antarctica is an example of a/an _______ glacier.
A. continental
Continental glaciers are continuous masses of ice that are much larger than alpine glaciers. Small continental glaciers are called ice fields. Big continental glaciers are called ice sheets. Greenland and Antarctica are almost entirely covered with ice sheets that are up to 3500 m (11 500 ft) thick.
Q. The process by which wind picks up particles of loose sediment and carries them away is known as
Q. The process by which wind picks up particles of loose sediment and carries them away is known as
A. deflation
Q. The zone of _______ is located below the equilibrium line of a glacier.
A. ablation
Wind erodes the Earth’s surface by removal of loose, fine-grained particles by turbulent eddy actions and it is called Deflation. Regions that experience intense and sustained erosion are called deflation zones. Abrasion refers to grinding of the rock surfaces with particles captured in the air.
Q. During wind erosion, the smallest particles of sediment, composed mostly of silt and clay, are most likely to move primarily by
Q. During wind erosion, the smallest particles of sediment, composed mostly of silt and clay, are most likely to move primarily by
A. suspension
Q. Glaciers are most likely to advance during _______ summers.
A. cool
Q. Wind speed and _______ determine how quickly abrasion will occur.
A. particle size
Q. The process of glacial erosion that works similarly to sandpaper is called
A. abrasion
Q. The Southern Plains region of the United States that experienced a long drought and heavy wind erosion during the 1930s was called the _______.
A. dust bowl
