<span>The observation of rocks in several mountainous belts that today are separated by oceans provides evidence of continental drift. Continental drift is the displacement of continental masses relative to each other. The Appalachian mountain belt in eastern North America ends off the coast of Newfoundland. Mountains of the same age with rocks and similar structures are found in the British Isles and Scandinavia, when these land masses come together, the mountain ranges form an almost continuous belt.</span>
Answer: The two major geographic features provided on the east and west boundaries of piece of land are:
1. The land is "Louisiana Purchase".
2. The east boundary is "Mississippi".
3. The west boundary is "The Rockies".
Explanation: The Louisiana purchase is a piece of land of about 530,000 acres which was sold by France to the US President which was Thomas Jefferson in 1804.
A farmer would choose to live in this area most likely because the land in here has many agricultural advantages that can be utilized for farming. Also, these lands are known to be the most fertile in that area. Flooding also helps in preventing weeds and keeping the soil healthy.
Answer:
At the boundary with the core.
Explanation:
The mantle is the second layer from the top. It is bordered by the lithosphere above it, or rather by the crust, and by the outer core below it. The mantle is a layer which is in viscous state, being mostly consisted of molten metals and rocks. The temperature of this layer is not the same all throughout it, but it varies a lot. The temperature at its top part is around 200 C degrees, while the temperature at its bottom is around 4,000 C degrees. There's two reasons for this. One is that the core is very hot, so it makes the bottom part of the mantle very hot as well, and the other one is that the lithosphere is much cooler, as well as constantly getting new, cold, crust in it, which makes its top part much cooler. The mantle is the layer responsible for the movement of the tectonic plates on the surface, as it is the layer where the convection currents occur and drive the plates' movement.
Small antennas on the spacecraft can beam weak radio signals back to earth meaning it can in some way communicate
