antartica Flashcards
why is antarctica cold?
Antarctica is covered by the largest ice sheet on Earth, which reflects most of the sunlight that reaches it. The ice also cools the air directly above it.
antarctica is dry cold and?
windy
what ocean surrounds antarctica?
southern ocean
antarctica’s is really dry it’s classified and a?
dry dessert
a greenhouse gas causing our planet to warm up
C02 ,Methane
it’s a small insect that eats phytoplankton
krill
The name of the agreement signed by multiple countries to protect antarctica?
The Antarctica treaty sysetem (ATS
coldest temperature ever recorded
-89
how many days of darkness are there in antarctica

1 good thing about tourist in antarctica?
When people see it and are told they’ll be aware of antarctica’s problem and want do everything they can to help (like not riding a car)
1 bad thing about tourist in antarctica
Tourist might not follow the rules of antarctica and there isn’t great medical help so you’d be risking your life
is antarctica in the south or north pole?
south pole
is antarctica a continent or a frozen sea?
continent
Which ocean surrounds antarctica?
southern ocean
how do you calculate temperature range
First identify the highest and lowest temperatures
Subtract the lowest temperature from the highest temperature
what to herbivores eat?
plants
plants that take energy from the sun and covert it into food are called what?
producers
what process do plant use to covert the suns energy into food
photosynthesis
is the greenhouse effect a good thing
GOOD -The greenhouse effect is responsible for the Earth’s surface temperature being warm enough for life to exist. Without the greenhouse effect, the Earth’s average temperature would be around -18°C, much colder than the 20th century average of 14°C.
is the enhanced greenhouse greenhouse effect a good thing?
The enhanced greenhouse effect is bad because it causes global warming and climate change, which have many negative consequences. FOR EXAMPLE -a rise in sea levels
what type of radiation come out the sun??
short wave UV
what is trapping the long-wave infrared in the atmosphere
greenhouse gases for example methane and C02
how is climate change causing sea levels to rise
Climate change is causing sea levels to rise because the earth is warming up which is also causing antarctica to warm up and the ice sheets and ice in general are falling into the water which have a drastic change on the sea levels
List ways humans adding more greenhouse gases to the atmosphere
Burning fossil fuels: Burning coal, oil, and natural gas to produce energy for manufacturing, transportation, and other uses releases carbon dioxide and nitrous oxide into the atmosphere.
Deforestation: Cutting down trees releases the carbon stored in them into the atmosphere. Trees help regulate the climate by absorbing carbon dioxide.
Mining and construction: Mining and other industrial processes release gases, as does the construction industry.
Give one reason antarctica is cold
Antarctica is covered by the largest ice sheet on Earth, which reflects most of the sunlight that reaches it. The ice also cools the air directly above it
other than climate change how are humans potentially damaging antarctica
Overfishing: Overfishing of fish species, especially krill, which is the base of the Antarctic food chain
Hunting: Hunting of top predators like seals and whales
give one reason tourism might be good for antarctica
Tourism helps raise awareness of the need to preserve Antarctica and helps fund Antarctic research
give one reason tourism might be bad for antarctica
- As tourism increases, wildlife could abandon their normal places of habitation if they are regularly disturbed.
How do you figure out the percentage for 5000 to 51000 in 50 years?
answer is 920%
is military activity allowed in antarctica?
no
ate tourist allowed to stay overnight of antarctica??
no they stay in a boat
how have research station be built to cope with life in antarctica
the legs are extendable? there easy to move
Satellite links
Research stations have satellite links to the outside world so they can communicate
