True

76
Q

How do extra fertilizers in farming affect the environment

A

Extra fertilizers from farming go into runoff and enter nearby waterways, such as rivers and lakes. These fertilizers are a treat for algae, which grows to cover the water’s surface, but as the algae decays, they use oxygen from the water, leaving less oxygen for fish and other aquatic animals

77
Q

Eutrophication Definition

A

Enrichment of nutrients in an aquatic environment that causes excessive growth of aquatic plants, especially algae, which increases bacterial growth and consumption of oxygen, resulting in depletion of oxygen in the environment

78
Q

A
  • It can destroy habitats of many species
  • It uses large amounts of fresh water
  • Causes soil erosion and desert formation
  • Introduces pollutants into the environment

Farmers liked DDT since it was cheap, easy to spray, and kept insects away

81
Q

How does DDT negatively effect other wildlife

DDT is toxic to other wildlife and can block the absorption of calcium in many organisms

82
Q

When was DDT banned in the US

A

1972

83
Q

How does DDT affect birds

A

In the case of birds, DDT’s impaired calcium absorption can interfere with reproduction by preventing proper formation of egg shell, making the eggs very fragile

84
Q

What is the negative impact of smog

A

Smog, created by burning fossil fuels, damages plants and causes people to have respiratory problems

85
Q

What is the negative impact of acid rain

A

Acid rain - pollutants carried in precipitation - harms fish, trees, soil, microorganisms, and manmade objects

Carbon Monoxide and Sulfur Dioxide

87
Q

It lowers its pH

89
Q

What is a wetland

A

A wetland is land that, at least some of the time, is covered by shallow waters or has waterlogged soils

90
Q

Why are Wetlands important

A
  • They are a rich habitat for many plant and animals species
  • They help prevent flooding
  • They filter excess nutrients, sediments, and even pollution from the water that flow through them
91
Q

Why have humans drained wetlands

A

Humans have drained wetlands to build roads, parking lots, buildings, and landfills

92
Q

What happens when rain is not soaked into the ground

A

When rain is not soaked into the ground of wetlands, it runs off directly into lakes and rivers carrying pollutants, organic materials, and excess nutrients

93
Q

Why is the air temperature in cities warmer than the temperature in the country

A

The air temperature in cities can be warmer than in the surrounding country sides since asphalt and concrete absorb heat from the sun and release it slower than plants overnight

94
Q

Why do people build dams

A

People build dams to control flooding, to improve water supply , and to produce electricity

95
Q

What happens to the land upstream from a dam

A

Land upstream of the dam becomes flooded as artificial lakes or reservoirs form. Because the water is no longer flowing quickly, sediment builds up in lakes, and the temperature of the water increases

96
Q

Why is there less sediment downstream from a dam

A

Since the sediment stays upstream

97
Q

How is water down stream from a dam

A

The water down stream is clearer, so sunlight can penetrate the water more easily and weed growth increases dramatically

98
Q

What does the lack of sediment downstream of a dam cause

A

Coastal erosion

99
Q

True or False: Without periodic flooding sediment - rich water, the fertility of the land downstream from the dam is reduced

A

True
