EE 105 MIDTERM 2 EXAM LATEST UPDATED
Floodplains are flat surfaces adjacent to rivers formed by erosion during floods.
False
The shallow part of a stream occurs on the outside of a turn.
False
The role of erosion is greater than that of deposition at high elevations of a
stream's longitudinal profile.
True
Erosion by a stream occurs mostly on the outside of a turn.
True
Erosion and deposition are equally balanced along lower (downstream) portions
of a stream's longitudinal profile.
True
A river's width, depth, velocity, and discharge all increase downstream.
True
The average annual probability of a 50-year flood at a given location is 2%.
True
Floodplains are good for farming and livestock.
True
The rise of the Alps and Himalaya Mountains at 40 to 60 million years ago
contributed to cooling of the planet.
True
Aretes are large U-shaped valleys carved by glaciers.
False
,The only significant period of glaciation on the Earth was during the
Pleistocene.
False
Glacial erratic refers to the disrupted nature of landforms left from glacial
retreat.
False
The coastal Atacama Desert of Chile, one of the world's driest, has its moisture
taken by the Andes.
True
A bajada is a dry lake bed in the desert.
False
The flat erosion surface formed by running water at the edges of retreating
desert mountains is termed desert pavement.
False
The steep side of a sand dune or ripple mark is on the upwind side.
False
Tropical deserts occur along equatorial latitudes.
False
Desert regions of Earth are increasing in size today.
True
A rain shadow desert forms downwind from mountains
True
Along the equator, air rises creating atmospheric low pressure and wet climate
and along the tropics (25-30 degrees N and S of the equator), falling air creates
high pressure and dry climate.
True
Coastal deserts occur on the downwind side of mountain ranges.
, True
Chlorofluorocarbons release dangerous levels of fluorine and chlorine forming
acid rain.
True
Upper atmosphere or stratospheric ozone is created by lightning.
True
Chlorofluorocarbons and methyl bromide breakdown in the upper atmosphere
or stratosphere releasing Cl and Br, respectively, which in turn destroy ozone.
True
Upper atmosphere or stratospheric ozone accumulates from smog that rises
from near the ground.
False
Sand accumulated on the north side of a groin indicates that the direction of
longshore drift is to the north.
False
Ocean waves that have a long wavelength will generate surf farther from shore
than those with a short wavelength.
True
Marine terraces are an indication of uplift or lowering of sea level.
True
Sea stacks represent erosional remnants following sea cliff retreat.
True
Some clay minerals expand in the presence of water creating unstable land
surfaces.
True
Granite weathers rapidly in the presence of rain water.
