I believe the first one is 'physical geography' :-)
Crust:outer silicate solid crust
mantle:highly viscous
core:solid inner core
The shockwave from an undersea earthquake causes 'ripples' in the ocean which are very large swells. When the bottom of the swell touches land, it must build up higher to maintain it's size. Therefore when it approaches the beach, water is drawn away from the beach to compensate for the ocean depth getting shallower under the tsunami swell. More water is drawn from in front of the swell than behind due to the movement of the swell.
Answer:
plains
Explanation:
<u>It has been noted that the density of road infrastructure is higher in the plains.</u>
This is because the terrain is leveled and easier for building, which makes it more likely for cities and settlements to be built here. If the population of the region is higher, there is more need for the roads and traffic to be built.
Additionally, it is easier to drive through the plains than to through the mountains, which is why roads will be built in the plains more likely. When the terrain is leveled, <u>roads can also be built through the forests and deserts.</u>
