Groundwater

 

Lab Questions: Activity 3, A-G and I, pg. 273, and Activity 4, A 1-6.

__________ _______ is the top of the saturated layer of water in the ground.

Permeable means water can flow through the soil and impermeable means it can't.

Hydraulic gradient is the slope of the water table.

  • It is equal to the difference in elevation between two points divided by its ____________.
    • ex. What is the slope if the diiference in contour lines reads 10 and 7 cm and the distance between them is 2 meters?
  • The slope of the water table determines the __________ of water flow. Water moves perpendicular to the isolines of water table height.

Karst topography is limestone that's been differently dissolved by rain water. It may be filled with sinkholes, solution valleys, springs and _________________!!

Glacier- a mass of flowing land ________ derived from snowfall.

  • Zone of accumulation- where the snow and ice ____________.
  • Zone of abulation (wastage)- where the snow and ice ____________ back.

Glacial polish- smooth bedrock caused by glacial ________

Glacial scratches- parallel linear grooves in bedrock caused by glacial __________

Till- __________ mixture of rock debris carried and deposited directly by a glacier. It ranges in size from clay to boulders.

Moraine- an accumulation of till

Stratified drift- has been ________________ transported by melt water and is sorted

 

Two major glacier types:

 

Mountain Glaciers

Be able to identify the following features on a topographic map:

Erosional:

  • horn- steep sided _________-shaped peak produced by erosion by glaciers
  • arete- sharp jagged, _________ edged ridge between two glaciated valleys
  • cirque- _______ shaped depression on a high moutain slope formed by a cirque glacier
  • u-shaped valley- shape of a valley scoured by a glacier
    • v-shaped valley- shape of a valley scoured by a river
  • hanging valley- a glacial trough of tributary glacier elevated above the _______ trough

Depositional:

  • lateral moraine- a linear pile of rock fragments deposited at the _______ of a glacier
  • medial moraine- a long narrow pile of rock fragments carried on top of the ___________ of the glacier- usually formed when two glaciers meet uphill.
  • tarn- small ________ in a cirque.

 

Continental Glaciers

Depositional:

  • outwash plain- plain formed by _________ like deposition of outwash (stratified drift by meltwater)
  • kettle lake- small lake in glacial drift formed by melting ________ of ice
  • finger lake- long narrow ________ that was cut into bedrock by glacier.
  • esker- long, narrow _________ of drift deposited under a glacier by meltwater.
  • drumlin- an elongated ridge of glacial till deposited under a glacier and elongated with the _________ end of the drumlin pointing the way the ice came.
