S8.D.1.3 Describe characteristic features of Earth’s water systems or their impact on resources. Reference: 3.5.7.D, 4.3.7.B, 4.1.7.A, 4.1.7.B, 4.1.7.C
S8.D.1.3.1 Describe the water cycle and the physical processes on which it depends (i.e., evaporation, condensation, precipitation, transpiration, runoff, infiltration, energy inputs, and phase changes).
S8.D.1.3.2 Compare and contrast characteristics of freshwater and saltwater systems on the basis of their physical characteristics (i.e., composition, density, and electrical conductivity) and their use as natural resources.
S8.D.1.3.3 Distinguish among different water systems (e.g., wetland systems, ocean systems, river systems, watersheds) and describe their relationships to each other as well as to landforms.
S8.D.1.3.4 Identify the physical characteristics of a stream and how these characteristics determine the types of organisms found within the stream environment (e.g., biological diversity, water quality, flow rate, tributaries, surrounding watershed).

  • Earth is the only planet in our Solar System that has liquid water
  • two hydrogen atoms bound to one oxygen atom comprises a water molecule
  • water exists on Earth naturally in all 3 states of matter: solid, liquid, gas
  • water is a polar molecule; this means that a portion of it is lightly positive and another portion slightly negative in electrical charge
  • because of its polarity, water exhibits a property called cohesion (it likes to stick to itself) and adhesion (it likes to stick to other things)
  • water is the UNIVERSAL solvent as it dissolves so many solutes!
  • water is a heat sink - it hold its temperature very well due to its high capacity for heat


BLUEBOOK CH. 21 Section 2 - Shaping the Land
1) All of the land that gathers water for a major river is the river's DRAINAGE BASIN. Most of the central USA serves as the drainage basin for the _ River Watershed.

2) How does the valley of a young stream differ from that of an older one?

3) Explain these land features and describe how they are formed from water interactions on Earth:
a. Stream Deposits
b. Floodplains
c. Deltas
d. U-Valleys
e. Moraines
f. Kettle Lakes
g. Horns

BLUEBOOK CH. 21 Section 3 - Groundwater
1) What is the water table?
2) Explain infiltration.
3) Define aquifer and give 2 examples of stones that are good aquifers and explain WHY (using the terms porosity and permeability).
4) What is an artesian well and how does it form?
5) Give an example of an aquitard rock.
6) Give some examples of groundwater pollution.
7) Research the dangers of the Hydro-Fracturing Marcellus Shale technique, and discuss its environmental dangers to groundwater.
8) Research the receding Everglades wetlands system of South Florida and explain how diveristy of those organisms suffers from such habitat destruction.
