New cards
Water hyacinth
It forms dense mats, reducing sunlight for submerged plants and aquatic organisms, crowding out native aquatic plants, and clogging waterways and intake pipes.
7
New cards
Zebra mussels
They can attach to almost any hard surface—clogging water intake and discharge pipes, attaching themselves to boat hulls and docks, and even attaching to native mussels and crayfish.

11
New cards
tectonic plates
The movement of _______ causes volcanoes and mountains to form, which can also contribute to changes in the climate
12
New cards
mosquitoes
Due to global warming, ______ have more places to breed, which increases malaria, dengue fever, Zika virus, and yellow fever rates.
13
New cards
Antarctica
The main ice-covered landmass is ________ at the South Pole, with about 90% of the world’s ice and 70% of its freshwater.
14
New cards
50%
The total surface area of glaciers worldwide has decreased _____ since the end of the 19th century.
15
New cards
Sea-level rise
________ threatens to inundate many coastal wetlands, threatening biota that cannot move inland due to coastal development.
16
New cards
absorb
As the oceans _______ more heat from the atmosphere, sea surface temperatures rise and ocean circulation patterns change.
17
New cards
store
As the oceans _____ a large amount of heat, even small changes in these currents can have a large and lasting effect on the global climate.
18
New cards
carbon dioxide
The world’s oceans contain more _______ than the atmosphere.
19
New cards
methane
Agricultural activities, waste management, and energy use all contribute to _______ emissions.
20
New cards
nitrous oxide
Fertilizer use is the primary source of _________ emissions.
21
New cards
infrared radiation
When sunlight strikes Earth’s surface, some of it is reflected back toward space as ________ (heat).
22
New cards
Greenhouse gases
It absorb this infrared radiation and trap the heat in the atmosphere.
23
New cards
global warming
Due to ________, mosquitoes have more places to breed, which increases malaria, dengue fever, Zika virus, and yellow fever rates.
24
New cards
Ocean currents
________ carry heat around the Earth.
25
New cards
Atomic oxygen
________ can combine with oxygen molecules to form ozone.
26
New cards
Stratosphere
Contains approximately 97% of the ozone in the atmosphere, and most of it lies between 9 and 25 miles (15-40 km) above Earths surface
27
New cards
UVA
It is closest to blue light in the visible spectrum and is the form of ultraviolet radiation that usually causes skin tanning
28
New cards
UVB
It causes blistering sunburns and is associated with skin cancer
29
New cards
UVC
It is found only in the stratosphere and is largely responsible for the formation of ozone
30
New cards
Ozone Layer
A belt of naturally occurring ozone gas that sits between 9 and 19 miles (15-30 km) above Earth and serves as a shield from the harmful ultraviolet B radiation emitted by the sun
31
New cards
Ozone
A highly reactive molecule and is constantly being formed and broken down in the stratosphere
32
New cards
Chlorofluorocarbons
These are nonflammable chemicals that contain atoms of carbon, chlorine, and fluorine
33
New cards
Halocarbons (halons)
These are organic chemical molecules that are composed of at least one carbon atom with one or more halogen atoms; the most common halogens are fluorine, chlorine, bromine, and iodine
34
New cards
Agriculture
Mostly comes from the management of agricultural soils
35
New cards
Commercial and residential buildings
On-site energy generation and burning fuels for heat in buildings or cooking in homes
36
New cards
Energy supply
The burning of coal, natural gas, and oil for electricity and heat is the largest single source of global greenhouse gas emissions
