Water at Work
A river starts as a steep channel in the mountains. It then leaves the mountains and enters a flatter area of land. It meanders across a plain and then enters the ocean. The river slows down and enters the ocean, forming this landform
What is a delta?
In places where there is loose sand and strong wind, the wind can pick up the sand and carry it. When the wind slows, it deposits the sand.
What are sand dunes?
These lines on a topographic map are darker and include measurements.
What are index contour lines?
This system allows users to combine different map and image layers to study Earth's surface.
What is Global Information Systems
This is formed after a glacier moves through a streambed
What is a U-Shaped valley?
A river overflows its banks and deposits sediment.
What is a floodplain?
Rain can trigger this type of rapid mass movement as it mixes with soil.
What is a mudslide?
Lines on a topographic map can be useful in deciding how to climb a mountain. This landform is shown by lines that are super close together.
What is a steep slope?
This object commonly used in remote sensing for purposes such as measuring the weather.
What is a satellite?
These features on a map form a V-shape pointing uphill and in the opposite direction in which they flow.
What are streams?
This process happens as Slightly acidic water dissolves certain rocks underground to form a cavern.
What is erosion by groundwater
Fine-grained sediments of quartz, feldspar, hornblende, mica, and clay deposited by the wind
What is loess?
You are using a topographic map. There are bold lines every 150 m of elevation change with 5 lines between them. Each line represents _____ elevation change.
What is 30 meters?
This system is commonly used for navigation and is created by sattelite images.
Global Positioning System
These forces are responsible for the changes we see as streams form deltas in oceans.
What are erosion and deposition?
A stream cuts into its surroundings and gradually wears away rock and soil. Over time, this can create this type of large landform.
What is a V-shaped Valley?
The rock material carried and deposited by glaciers.
What is glacial drift?
Change in elevation over a change in distance.
What is gradient?
The process of gathering and analyzing information about an object without physically touching the object.
What is remote sensing
Two areas have the same amount of rainfall. Area A has thick vegetation covering the soil, while Area B has very little vegetation. Compared to area A, Area B will experience ___________ ___________.
What is more erosion?
These two factors contribute to erosion on shorelines
What is wave intensity and rock hardness?
the breaking down or dissolving of rocks, minerals, and soils on the Earth's surface in place, without moving them.
What is weathering?
1 cm on the map = 100,000 cm on Earth's surface
What is a scale?
1:100,000
A biologist wants to study the relationship between land slope and vegetation. Along with aerial imagery, heshould also use this type of map layer.
What is topographic map layer?
The name of this Unit
What is Earth's Surfaces?
