A neighborhood in a small Texas town had to be evacuated because the houses were sinking due to a problem in the aquifer. What is the most likely cause of this problem?
Heavy rains caused oversaturation of soil foundations.
Overbuilding in the area polluted the ground water.

Pollution cannot travel through soil to groundwater.
What definition BEST describes a watershed?
An area where water infiltrates the soil
An area where aquatic plants and animals thrive
An area where snow melts and changes into liquid water
An area that collects precipitation and drains it to the lowest point
How do humans impact the hydrosphere?
Human activities such as promoting biodiversity and reducing carbon emissions
Human activities such as pollution, deforestation, and urbanization
Human activities such as planting trees and conserving water
Human activities such as reducing pollution and protecting wetlands
Runoffs recharge lakes and streams.
True
False
The hydrologic cycle is powered by energy from what?
The Sun
The Moon
The Wind
Human interaction
What term refers to pollution that comes from a specific location, such as a sewer pipe emptying waste into a river?
Hydrosphere
Natural resources
Nonpoint-source pollution
Point-source pollution
Explain the water cycle and its importance to the hydrosphere.
The water cycle only affects saltwater sources and has no impact on freshwater
The water cycle is not important to the hydrosphere as it has no impact on the distribution of water
The water cycle is important to the hydrosphere but does not support any ecosystems
The water cycle is important to the hydrosphere as it regulates the distribution of water across the Earth, replenishes freshwater sources, and supports various ecosystems.
What is the consequence of too much carbon in the ocean?
Increased fish populations
Ocean acidification and long-term damage to ocean habitats
Improved water clarity
Enhanced coral growth
Describe the importance of oceans in the hydrosphere.
Oceans have no impact on the hydrosphere
Oceans do not affect weather patterns
Oceans are only important for fishing
Oceans help regulate the Earth's climate, provide habitat for marine life, and influence weather patterns.
The process of taking fish out of the ocean before they have a chance to reproduce is called?
Invasive species
Over-fishing
Artificial reefs
Recycling
What term refers to pollution that comes from many sources rather than from a specific site, such as fertilizer runoff from farms or residential yards?
Hydrosphere
Natural resources
Nonpoint-source pollution
Point-source pollution
In science class, students learn about dead zones in the ocean. Dead zones are areas that form when excess nutrients enter the ocean, leading to oxygen depletion.
Which explanation BEST describes the human industry most impacted by this?
Tourism is affected because dead zones make coastal waters less attractive.
Without adequate oxygen commercial fishing is affected because fish cannot survive.
Marine transportation is affected because dead zones alter shipping routes.
Offshore oil drilling is affected because the drilling platform requires oxygen-rich water.
Which actions HARM water quality?
Choose TWO.
planting trees along riverbanks
using fertilizers excessively
cleaning up oil spills promptly
dumping industrial waste into rivers
installing water-efficient fixtures
Which human activity can lead to water pollution by introducing harmful disease causing pathogens?
dumping industrial waste into rivers
overfishing in coastal areas
allowing untreated sewage to flow into bodies of water
constructing dams on rivers
using fertilizers in agriculture
Which statement BEST explains how excessive algae blooms impact the stability of the ocean system?
Excessive algae blooms can deplete oxygen levels in the water through decomposition of the algae, leading to low oxygen levels and negatively impacting marine life.
Algae blooms lead to a decrease in hydrogen in the water, affecting marine ecosystems.
What term refers to a substance that enters the environment and can harm living things?
Hydrosphere
Natural resources
Renewable resource
Pollution
Review the graph showing marine fishing rates.If the fishing rate in Asia continues to grow, what will most likely happen as a result?
The fish population will continue to rise.
A wide range in ocean temperatures will be seen worldwide.
The U.S. human population will decline.
The overfishing will cause an imbalance in marine ecosystems.
What is one way humans are trying to positively impact the ocean?
Fishing
Drilling for oil and natural gas
Creating artificial reefs
Transporting goods in ocean vessels
Which process is responsible for carrying fertilizers that have been applied to crops into bodies of water, such as a river?
Runoff
Evaporation
Ocean Currents
Tectonic Plate Movement
What do we depend on the ocean for?
Food
Oxygen
Transportation
All of the above
Which risk is associated with oil drilling?
It extracts radioactive elements which are health risks for workers.
It removes land from beneath the surface which can cause sinkhole.
It can lead to an oil spill in the middle of the ocean.
It removes soil which increases oil erosion.
Algae blooms...
increase oxygen which causes dead zones.
decrease oxygen which causes dead zones.
occur when the amount of algae decreases in surface water.
occur only near the equator.
This graph shows the sources of the nitrogen entering the Gulf of Mexico as pollution. What is one conclusion you can make based on the information in the graph?
