| What is a river? | A surface water finding its way over ladn from higher altitude to lower altitude, all due to gravity |
| What is a lake? | Water that has made its way to a place that is surrounded by higher land on all sides |
| What is a small creek? | The place that initially collects flowing water from run off when it goes downhill |
| What is a stream or river? | The water body that is formed when small creeks merge |
| What is a reservoir? | A water body that is formed when man builds a dam to hinder a river's flow and form a lake |
| What is an ocean? | The water body where rivers eventually flow into |
| Where does river water come from? | 1) rain, and 2) water tables |
| How might a water table fill a river? | If water eats into the ground, and hits the water table, then _______ |
| What is a headwater? | Place where the river begins (e.g. might be in the mountains) |
| What is an oxbow lake? | U-shaped lake water body formed when a wide meander from the mainstem of a river is cut off to create a lake |
| What is a meandering stream? | One that To follow a winding and turning course |
| What is the delta of a river? | A usually triangular mass of sediment, especially silt and sand, deposited at the mouth of a river. Deltas form when a river flows into a body of standing water, such as a sea or lake, and deposits large quantities of sediment. They are usually crossed by numerous streams and channels and have exposed as well as submerged areas |
| What is the mouth of a river? | where the river discharges into the ocean, a major lake, or a desert basin. |
| What is an ocean? | is a major body of saline water |
| How does an oxbow lake form? | An oxbow lake is a crescent-shaped (often temporary) lake that is formed when a bend in a river is cut off from the main channel by the forces of erosion. An oxbow lake will slowly be created as soil erodes and re-deposits, changing the river's original course. |
| What is transpiration? | The process where the water leaves plants and rises into the atmosphere |
| What is the main source of energy/ cause of the water cycle? | the sun |
| What is the difference between run off and infiltration? | Run off goes into the bodies of ater, and infiltration goes into the ground |
| What is the head of a river? | Where the river begins |
| What is the mouth of the river? | Where the river ends |
| Where do most rivers eventually end up? | oceans |
| How does the water get from the mouht of a river back to the headwaters? | the water cycle |
| Define "moraine" | An accumulation of boulders, stones, or other debris carried and deposited by a glacier. |
| Define "watershed" | Area of land that is drained by a river |
| Define "continental divide" | The ridges of land that separate two watersheds |
| What are examples of how water does work on the land that it flows through: | 1) deposits silt in floodplains, makes good farm land, 2) forms new lakes, such as an oxbow lake 3) makes canyons |
| What is erosion? | removal of material from a channel or bank |
| What is deposition? | Accumulation of transported particles to another location on the streambed or floodplain |
| What is transportation? | Movement of eroded particles by dragging or in solution |
| How are deposition and erosion related? | Deposition is the opposite of erosion |
| What is a benefit of deposition? | Makes good farming land |
| What are the downsides of deposition? | It may flood or block the channel |
| Compare the speeds of a young river and an old river. | The young river has a fast flow, and the old river has a slow flow. |
| Compare how much a young river and an old river can lift and carry. | A young river can lift and carry much erosion, and an old river can carry little erosion. |
| Compare the deposition of a young and old river. | A young river does little deposition and an old river does much deposition. |
