Vocab Definitions
Dead Zone
A near-shore area of water with little or no dissolved oxygen and, therefore, very few organisms.
Definition of the Water Cycle
The movement of water through the air and land
Definition of Weathering
An earth process that breaks down rocks into smaller pieces.
Name two types of maps
Topographic and Street
Name a Human impact on the environment
Increased erosion, destruction of habitats.... etc.
Erosion
The removal of sediments from an area
Evaporation
Process that moves water from Earth's surface to the atmosphere
What are three processes that change the Earth's surface?
Deposition, Erosion, Weathering
Where water on Earth is primarily found
Oceans
What can lead to an excess of nutrients in the water?
Farming, fertilizers
Sediments
Small pieces of earth such as rocks, shells and other debris
Precipitation
Process that pulls water down to Earth's surface from the atmosphere
Smaller rocks allow faster water flow than bigger rocks.
Elevation on maps is shown with what kind of lines?
Contour Lines
Are nutrients always helpful? Explain why or why not
When there is an excess of nutrients, that can harm habitats and organisms that live in the habitats
Deposition
Sediments that settle out of the flowing water, ice, or winds and drop to the ground due to slowing water.
Condensation
Process that leads to the formation of clouds
What is an example of a human impact on Earth's Systems?
Hydroelectric dam on a river
The closer together the lines are on a topographic map, the....
The steeper the slope.
What is a negative consequence to building next to a river?
Disruption of erosion and deposition.
A fan-shaped landform that develops where sediments are deposited in one area as a result of flowing water, such as a stream or river, entering still water, such as a lake or ocean
Transpiration
Process where plants lose water through their leaves that is then evaporated back up into the atmosphere
How can runoff change Earth's surface?
Transports sediments and can reshape land through erosion and deposition
How can maps help with monitoring erosion and deposition?
Can help to chart how much the landscape has changed over time due to excessive erosion or deposition
Name an environment change to water and and environmental change to land due to human activity.
Nutrient pollution due to fertilizers... etc.
Reduction of plants and animals due to building/construction.... etc.
