What is the continental drift theory? (in your own words)
Continental drift theory is that there was a big continent called Pangea. It eventually split up because of plate tectonics into the continents we know today.
Why do Earthquakes occur? (Use crust, tectonic plates, mantle, core, slabs, subduction, collide)
The Earth is made of a crust, mantle, and core. The crust is made of tectonic plates that “float” on the mantle. The plates are unbending slabs. Earthquakes happen during subduction, or when one plate goes under the other. It also happens when two plates collide and slip.
What are the five oceans?
Pacific, Atlantic, Indian, Southern, Arctic
What percentage of the earth does the Pacific Ocean cover?
28%
What are the two ways tsunamis are caused?
Underwater Earthquakes and Volcanic Eruptions
What is the last name of the man who “baptized” the Pacific Ocean “el Pacifico”?
Magellan
What is the meaning of Melanesia?
Islands of Black
What is the meaning of Polynesia?
Many Islands
What is the meaning of Micronesia?
Tiny Islands
True or False: Continental islands are still connected to the continent by an underwater continental shelf.
True
True or False: Continental islands have a wider variety of plants and animals than volcanic island or atolls.
True
True or False: Volcanic Islands are often formed by the subduction of one plate under another.
False
How were the Hawaiian Islands created?
They were created by tectonic plate movement over a hot spot in the earth’s surface far from the nearest plate boundaries.
Low island can be
A. Volcanic high Islands that have been worn down nearly to sea level
B. Formed from coral reefs
C. Both
C
True or False: The coral polyp is an animal.
True
What do corals eat?
Plankton
True or False: Corals can reproduce with each other or without.
True
What percent of corals are endangered?
60%
What is the goal that was set by the United Nations for the ICRI?
It is to stop and reverse the global destruction of coral reefs.
What do algae give to corals that is essential to their life?
The algae help coral take calcium out of the water and help cement the coral skeletons together.
What do corals give to algae that is essential to their life?
The coral gives the algae animal waste, which is plant fertilizer.
Explain what happens when an atoll is in the making. (Use sinking and eroding volcano, barrier reef, lagoon)
True or False: Atoll reef islands have no rivers and yet plants can grow on them because sands and corals can hold water.
True
True or False: Most plants and animals migrated across the Pacific from Asia.
True
When is the winter solstice?
12/21 or 22
When is the summer solstice?
6/21 or 22
What does El Niño bring?
Bigger waves
What is the difference between weather and climate?
Weather is the short term state off certain conditions at a given time or place. Climate is 30 - 50 years of similar weather patterns.
What do trade winds help people do?
It helps them sail
True or False: Trade windy occur during the rainy season.
True
True or False: The “doldrums” occur during the rainy season
True
What is the greenhouse effect? (Use sun’s rays, layer of gasses, trapped beneath, average temperature, suitable for life)
The greenhouse effect is when the sun’s rays pass freely through a layer of gasses. Some of the heat gets trapped beneath, and it keeps the planet at an average temperature that is suitable for life.
Place the Equator, The tropic of Cancer, and the Tropic of Capricorn on the right places on the map:

Why do we have seasons?
We have seasons because as the earth revolves around he sun, the tilt of the earth causes the sun to shine more directly on some parts
List three reasons why global warming is of a particular significance for the Oceania island nations and territories.
- The rising waters can drown low islands
- It kills the coral reefs in the ocean so there are more frequent tropical storm
- It brings more wide-spread diseases
Preparing s’mores over an open fire, eating a burger, and driving to the mall are all contributing to ____________.
Global Warming
