how do ocean currents work?
winds blow across the water and move it in circular patterns like the wind. water near the equator is warmed. when the warm water is close to land it heats up the air around.
what is a tsunami
a giant sea wave caused by underwater earthquakes and volcanic eruptions: cause major flooding and destruction.
what is a typhoon
a tropical storm in the region of the Indian or western Pacific oceans
what are different resources that come from the Pacific ocean
- many different plants and animals
- medicines from different species
- pearls
- metals such as nickel, copper, and manganese

Define Global Warming
a gradual increase in the overall temperature of the earth’s atmosphere
define the greenhouse effect
a process that occurs when gasses in the atmosphere prevent heat from the surface of the earth from escaping

most distant from the equator
receives less sun

how thick are they
98%
well over a mile
what is the antartic treaty
stated that antartica is a peaceful place for scientific investagatioins
what are the three key ideas of global warming
climate is getting warmer
caused by humans
harmful to both humans and biomes
what are the 3 most common greenhouse gasses
carbon dioxiode
methane
water vapor
what is the reason that greenhouse gas levels are rising
humans burn fossil fules such as coal oil and natural gas
name three pieces of evidence to support the global warming theory.
climate records
glacier records
rising levels of greenhouse gasses in the atmosphere
name three terrible consequences that scientist warn of global warming
some places will lose plants and animals not adapted to the warmer
crop-failure will lead to worldwide hunger
ocean temps will rise and melt the glaciers: coastal cities will be flooded
list the counter arguments to global warming
temeratures show little signs of warming
most surface temps are measured in big cities which are warmer because of buildings and concrete
some glaciers are growing
how do researchers study ice shelves
placing satellites to track them
spend time at observation posts examining temperature changes
