Chapter 14 - questions* 1-20 on pages 442-443
1. Streams collect water from runoff and discharged groundwater, and they conduct it from elevated regions of the continent down to the sea.
2. Dendritic drainage develops a dendritic network which looks like the pattern of branches connecting to the trunk of a deciduous tree.
Radial drainage form on a cone shaped mountain flow outward from the mountain peak.
Rectangular drainage channels form along the preexisting fractures and streams join each other at right angles, creating a rectangular network.
Trellis drainage develops across a landscape of parallel valleys and ridges, major tributaries flow down a valley and join a trunk stream that joins across the ridges.
3. Permeant streams exist where the water table lies above the bed of the channel or when large amounts of water enter the channel from upstream. Where the water table lies below the channel bed, streams are ephemeral.

The discharge of a stream in the total volume of water passing a point along the bank in a second. Most streams are turbulent, meaning that their water swirls in complex patterns.
5. Water meets friction and moves extra slow than at the surface near the middle of the stream.
6. Streams erode the landscape by scouring, lifting, abrading, and dissolving. The resulting sediment provides dissolved loads, suspended loads, and bed loads. The total quantity of sediment carried by a stream is its capacity. Capacity differs from competence, the maximum particle size a stream can carry. When stream water slows, it deposits alluvium.
7. Dissolved load- The ions of these dissolved minerals constitute a streams dissolved load. Suspended load- tiny solid grains that swirl along with the water.
Bed load- Consists of large particles such as pebbles, sand, or cobbles that bounce or roll along the stream floor.
8. A stream's competence is how big the particles are in a stream and capacity is how much sediment is
