Excessive pumping of groundwater can cause subsidence. This is a problem in Texas and Louisiana. What would happen to homes and buildings that were built on land which subsided?
settling and breaking of foundations
flooding when the ground sinks
both answers are correct
neither answer is correct
precipitation
any form of water that falls to Earth's surface from the clouds
the change of state from a gas to a liquid
the process by which plants release water vapor into the air through stomata; also the release of water vapor into the air by other organisms
the change of state from a liquid to a gas that usually occurs at the surface of a liquid over a wide range of temperatures
surface water
all the bodies of fresh water, salt water, ice, and snow that are found above the ground
the water that is beneath Earth's surface
the upper surface of underground water; the upper boundary of the zone of saturation
the path that a stream follows

Toxic
Sediment
Agricultural
Bacterial
Run-off is the water that -
Soaks into the ground
Always ends up in the oceans
Contains living organisms
Flows over land into a body of water
During a period of drought, members of a community may volunteer to water their lawns every other day, rather than daily. The most important benefit of this action is -
It fertilizes the soil
It reduces air pollution
It conserves the groundwater supply
It adds nitrogen to the soil
large amounts of nitrates/fertilizer in runoff
Coral reefs are endangered by
climate change
overfishing
pollution
all of the above

Is the following an example of a positive or negative impact on the earth's ocean systems?
Artificial reefs placed on the seafloor enhance marine life by creating new reef habitats.
Positive Human Impact on Ocean Systems
Negative Human Impacts on Ocean Systems
Is the following an example of a positive or negative impact on the earth's ocean systems?
Commercial fishing nets often times scrape the seafloor scooping up everything in its path. Dredge fishing destroys habitat and kills bycatch (fish, sharks, and other marine life caught unintentionally).
Positive Human Impact on Ocean Systems
Negative Human Impacts on Ocean Systems
Is the following an example of a positive or negative impact on the earth's ocean systems?
Fertilizers from farms runoff into rivers and create dead zones at the mouth of rivers in our world's oceans.
Positive Human Impact on Ocean Systems
Negative Human Impacts on Ocean Systems
Is the following an example of a positive or negative impact on the earth's ocean systems?
Fishing licenses regulate the number of fish and the size of fish that can be caught.
Positive Human Impact on Ocean Systems
Negative Human Impacts on Ocean Systems
Is the following an example of a positive or negative impact on the earth's ocean systems?
Fishing regulations create fishing seasons (time of year people are allowed to fish) to allow fish the opportunity to reproduce and increase species population.
Positive Human Impact on Ocean Systems
Negative Human Impacts on Ocean Systems
Is the following an example of a positive or negative impact on the earth's ocean systems?
Recycling trash helps prevent plastic and other unwanted trash from entering our ocean systems.
Positive Human Impact on Ocean Systems
Negative Human Impacts on Ocean Systems
Is the following an example of a positive or negative impact on the earth's ocean systems?
Human development in wetlands, estuaries, and protected bays.
Positive Human Impact on Ocean Systems
Negative Human Impacts on Ocean Systems
Which among the following would be the result of over fishing?

All of the above.
What are strategies that can be implemented to reduce/prevent overfishing?
Fishing quotas
Establishing laws
Marine protected areas
International standards for mesh size of nets
banning certain kinds of nets
What is a marine protected area?
An area where people can catch fish
An area where all fishing activities are prohibited
An area where only some fish species are allowed to be caught
An are where people can swim and snorkel
What is a fishing quota?
The number of fish that is not allowed to be fish in a fishery.
The money fishing companies get for catching fish
The maximum quantity of fish that is allowed to be removed from a fishery.
What are the effects of overfishing?
Drop in the fish population and fish species going extinct
Threatens the food availability as many people rely on fish as a source of food
Loss of jobs in the fish industry
People earning more money
New species being discovered
