Explanation:
The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's energy. This process increases the Earth temperature than it would be without an atmosphere.

First, look at the definitions involved.
hydrosphere - All the water on earth's surface such as lakes and seas.
lithosphere - The rigid outer part of earth's crust.
Now look at the available choices:
on mountaintops
* Bodies of water aren't too common up on mountain tops. Not a good choice.
inside glaciers
* Inside glaciers? Not touching earth, but lots of ice instead. Also not a good choice.
at volcanoes
* Not a lot of water here either. Bad choice.
along shorelines
* Sounds good. The boundary between water and earth. This is the right answer.</span>
So, the United States wanted to find more opportunity in different places than where they were currently at. Of course they would go and expand their territory. United States pretty much bought out their way across the continent, with New Orleans and West Florida for $10 million as an example. They possibly fought for a bit of it, but most of it was bought out. :)

Answer:
B. Isostatic equilibrium
Explanation:
Isostasy is a state of balance or equilibrium between the lithospheric plate and the underlying mantle, the asthenosphere.
Due to the weight of the lithosphere, part of it sinks into the plastic asthenosphere and settles to an equilibrium position. This is what causes changes and differences in elevation on the earth.
As with all natural processes, the earth in itself tries to achieve stability and equilibrium in all it parts. The crust and a portion of the mantle forms the brittle lithosphere. The lithosphere floats on the plastic mantle. Due to density contrast, portions of the lithosphere tends to sink into the mantle from time to time. The lithosphere reaches a point where it no longer sinks and establishes an equilibrium with the asthenosphere.
This isostatic adjustment that occurs within the earth is responsible for the changes in elevations from places to places.
When portions of the crust gets eroded, it becomes lighter and rises up. When materials are deposited in adjacent areas or glaciers forms, they add increasing weight to the crust and causes it to further settle within the asthenosphere.
