Which glacial landform is an elongated hill composed of till?
Drumlin
Which particles can the wind move most easily?
Wind transports small particles, such as silt and clay, over great distances, even halfway across a continent or an entire ocean basin. Particles may be suspended for days. Wind more easily picks up particles on ground that has been disturbed, such as a construction site or a sand dune.
Where are the large deposits of glacial loess primarily found?
Extensive loess deposits are found in northern China, the Great Plains of North America, central Europe, and parts of Russia and Kazakhstan. The thickest loess deposits are near the Missouri River in the U.S. state of Iowa and along the Yellow River in China. Loess accumulates, or builds up, at the edges of deserts.
Which process most likely created the valley?
These geological formations are created by running rivers and shifting glaciers. Valleys are depressed areas of land–scoured and washed out by the conspiring forces of gravity, water, and ice.
Which two locations have the greatest stream velocities?
Stream Flow and Sediment Transport Stream velocity is the speed of the water in the stream. Units are distance per time (e.g., meters per second or feet per second). Stream velocity is greatest in midstream near the surface and is slowest along the stream bed and banks due to friction.
Which location has the youngest bedrock?
The youngest unit exposed at the bedrock surface is the Upper Devonian Antrim Shale (fig.
Which agent of erosion is most likely to move sand dunes?
Wind can carry small particles such as sand, silt, and clay. Wind erosion abrades surfaces and makes desert pavement, ventifacts, and desert varnish. Sand dunes are common wind deposits that come in different shapes, depending on winds and sand availability.
Which ocean current has the greatest warming influence?
One of the strongest currents in the world, the Agulhas Current flows along the east coast of South Africa, transporting warm, salty water away from the tropics toward the poles.
At which location is the angle of insolation greatest at solar noon?
June 21st=highest angle of insolation=highest solar intensity=longest path of sun=sun directly overhead at 23.5 North of equator. December 21st=lowest angle of insolation=lowest solar intensity=shortest path of sun=sun directly overhead at 23.5 South of equator.
Where is insolation strongest?
At the equinoxes, solar insolation is at a maximum at the equator and is zero at the poles. At the summer solstice of the northern hemisphere, daily insolation reaches a maximum at the North Pole because of the 24-hour-long solar day.
What causes the angle of insolation to change?
Yearly changes in the position of the Earth’s axis cause the location of the Sun to wander 47° across our skies. Changes in the location of the Sun have a direct effect on the intensity of solar radiation. If the Sun is 45° above the horizon, the incoming insolation strikes the Earth’s surface at an angle.
Why is insolation 0 cm?
Why is insolation 0 cal/cm2/min from October through February at 90º N? Snowfields reflect sunlight during that time. Dust in the atmosphere blocks sunlight during that time. Intense cold prevents insolation from being absorbed during that time.
Why is less insolation received at the equator?
As you can see above, because of the curve of the Earth a sunbeam of Insolation hitting the Earth at higher latitudes has to spread out over a larger surface area than one reaching the Equator. Thus lowering the amount of Insolation per km2 in more Northerly and Southerly latitudes.
Which city was the greatest wind speed occurring?
For nearly sixty-two years, Mount Washington, New Hampshire held the world record for the fastest wind gust ever recorded on the surface of the Earth: 231 miles per hour, recorded April 12, 1934 by Mount Washington Observatory staff.
At which latitude does the Earth receive the greatest intensity of insolation on June 21?
23 and a half degrees latitude north
Where is insolation the weakest?
Insolation — Incoming Solar Radiation. The climate system begins with energy from the Sun. This means that the insolation is more concentrated near the equator and weaker near the poles.
Which Apex has the highest insolation?
Tropical Zone: This zone is is known to have the highest insolation.
