The Challenger expedition laid the foundation for all of oceanography. It was the first
serious expedition with the sole purpose of gathering information about the oceans. It helped
spark the movement that spread quickly to other areas of t

1. Explain how fertilizers can end up causing dead zones.
Initially, fertilizers are spread on crop fields to help them grow. But these fertilizers
end up washing into streams and rivers, which eventually end up in coastal water
1. Yes if the ocean basin in the Atlantic was narrower the currents would be more
concentrated as the same amount of water is forced to move through a smaller area.
2. Currents carry water over the globe and carry with it many things, they can carry
1. The Atlantic and Pacific oceans have a few differences in the physio-chemical
composition. The lower portions of the Atlantic ocean has less oxygen than the Pacific
which leads the pacific to hold much more life at the ocean floor. The Atlantic al
2. The clouds can both cool and heat the earth. The clouds can cool the earth by reflecting incoming
sunlight. They can also heat the earth by trapping infrared radiation from the earths surface and radiate
the heat back to the earth.
3. The climate
The single most important physical quality of water is its ability to be a liquid from 0 to
100 degrees Celsius. Since there is such a wide range of temperatures for water to be a liquid,
most of the water on the earth appears this way. If the range w
A convergent boundary will create a trench where one plate moves under the other and is
pushed down into the hot inner part of the earth where it is turned to magma and creates a
volcanic structure on the side of the boundary opposite the side where t
Sediment movement in major beach zones is caused by many factors. The major reason
that sediment gets carried is because of the movement of the fluid in the area of the sediment.
This can be caused by river flows as well as natural currents and tides.
Just like crust, mantle, and core; lithosphere, asthenosphere and mesosphere are terms
used to describe the inner parts of the earth. The crust, mantle and core are terms used to
distinguish between the composition of each layer. Lithosphere, astheno
