1 Water, Another Important Abiotic Factor (just like soil)

2 Remember the Water Cycle?

3 1.Groundwater – water located beneath the ground surface in between soil spaces. 2.Surface water – water collecting on the ground or in a stream, river, lake, sea or ocean. Two Types of Liquid Water: (based on its location)

4 Surface water

5 1.It rains or precipitation happens, 2.If the ground is dry, it absorbs water like a sponge, 3.This becomes groundwater, 4.When the ground can no longer hold anymore water, 5.The rain starts to runoff the surface of the land, 6.This runoff goes into streams, rivers, & lakes and becomes surface water. How Do You Get the Two Types?

6 Let’s Take a Look at Surface Water

7 Remember, water that is not absorbed by the ground runs-off and becomes surface water

8 Runoff - water that flows over the land surface. It becomes surface water like lakes, streams, rivers, and eventually the oceans. Definition:

9 What Makes a River Flow? …gravity, water from snow or rain falls on higher ground and flows to a lower point, typically the ocean. Ocean

11 From the Reading Guide: Parts of a River – 3 sections Looking from above Tributaries trunk Distributaries Drainage Basin

12 Drainage basin - the land areas that gathers precipitation water and directs it to a particular stream. Definition:

13 Drainage Basin sometimes used in a larger sense to include all the land that drains into a river system. Drainage Basin – sometimes used in a larger sense to include all the land that drains into a river system.

14 From the Reading Guide: Parts of a River – 3 sections Looking from above Tributaries trunk Distributaries Divide

15 Divide - the ridge of land that separates two adjacent drainage basins. Definition:

16 Pacific Ocean Atlantic Ocean

17 From the Reading Guide: Parts of a River – 3 sections Looking from above Tributaries trunk Distributaries Floodplain

18 Floodplain - flat or nearly flat land adjacent to a stream or river that experiences occasional or periodic flooding Definition:

19 floodplain - Definition:

20 From the Reading Guide: Parts of a River – 3 sections Looking from above Tributaries trunk Distributaries Meander

21 meander – a winding, turning bend in a river Definition:

22 From the Reading Guide: Parts of a River – 3 sections Looking from above Tributaries trunk Distributaries Oxbow lakes

23 Ox bow lake - a type of lake which is formed when a wide meander from a stream or a river is cut off to form a lake. Definition:

24 From the Reading Guide: Parts of a River – 3 sections Looking from above Tributaries trunk Distributaries Delta

25 Delta - a landform where the mouth of a river flows into an ocean, sea, desert, estuary or lake. Definition: The Nile River Delta

26 From the Reading Guide: Parts of a River – 3 sections Looking from above Tributaries trunk Distributaries Watershed

27 watershed - the region of land whose water drains into a specified body of water Definition: animation

29 From the Reading Guide: Parts of a River – 3 sections Looking from above Tributaries trunk Distributaries Alluvial Fan

30 Alluvial fan - a fan-shaped deposit formed where a fast flowing stream flattens, slows, and spreads typically at the exit of a canyon onto a flatter plain Definition:

31 From the Reading Guide: Parts of a River – 3 sections Looking from above Tributaries trunk Distributaries sediments

32 sediments- loose pieces of sand, silt and clay that come from the process of weathering and erosion that settle at the bottom of rivers and lakes Definition:

33 From the Reading Guide: Parts of a River – 3 sections Looking from above Tributaries trunk Distributaries Dams – man-made

34 dams- man made structure created for flood control that can create lakes for recreation and water storage. Some dams can create hydroelectricity. Definition:

35 From the Reading Guide: Parts of a River – 3 sections Looking from above Tributaries trunk Distributaries eutrophication

36 eutrophication- an increase in the nutrients and organisms in the life of a lake that eventually causes the lake to become dry land. Definition:
