1)

Definitely, the heat that drives the convection cells located in Earth originates in the inner core. I consider this option to be correct as inner core is the Earth's innermost part and its temperature could be approximately <span>5400 °C, so I bet this is the most suitable option.

2)
According to the fact that </span>magma plume ejected magma through a moving crust, this is a great example of a mid-ocean ridge, because this phenomenon<span> consist of an </span>underwater mountain system that were<span> formed due to the </span>plate tectonics. 
3)
 When an earthquake occurs, the actual point of earth movement is called crust and the point on the surface right above this is called the mantle. From the definitions of these two points you can see that their meaning cleanly coincides with the task.
4)
<span>As far as I remember, in order to prevent a mass erosion event, such as the 1930s Dust Bowl, farmers should k</span><span>eep the land irrigated. They say that it is very important to overflaw dry area in order to keep it in satisfying condition.
5)
Some scientists take s</span>eafloor spreading  as a basis and claim that in neares future, <span>slabs </span>lithosphere will split apart from each other again due to tectonic activities. Also, they assume that there is a big possibility that soon <span> tectonic plates will crash into each other and won't spread. 
</span>6) 
<span> The soil is the most essential point of the groving basis, its purpose is to make plants and trees grow, therefore we can make a conclusion that we can't imagine our life without it.
</span>7) You can include such information as<span> description of the motion of mantle material near the outer edge of it and show the model that clearly shows all the point you describe. Then you should tell about how things that you have seen can impact Earth.
</span>
I do hope it will be helpful!

Darina [25.2K]

Answer: at the equator the normal force will be 3.4N less and at the North Pole = 980N

Explanation:

So, we will start the Calculation by considering the equation below;

Fnet = F(g) - F(N); where Fnet = mv^2/ r.

Hence, F(g) - F(N) = mv^2/ r -------------(1).

Making F(N) the subject of the formula, we have;

F(N) = Gm1m2/r^2 - mv^2/r.

Thus, we have;

Gm1m2/r^2 = 6.68 × 10^-11 × (5.98 × 20^24) × 100/ 6.38 × 10^6 = 980N.

Also, we have;

mv^2/r = m4π^2r/T^2.

100 × 6.38 ×10^6 × 4π^2/(24 × 3600)^2 = 3.4N

Therefore, at the equator the normal force will be 3.4N less and at the North Pole = 980N.

South Asia is actually a ____________, a large landmass within a continent
bulgar [2K]
I don't know whether this was one of your options, but South Asia can be very well characterized as  a Sub-continent.

In fact, it's is commonly referred to as "the Indian Subcontinent" or even simply "Subcontinent". One of the reason for a distinction of this part of the land is that it lies on a different tectonic plate.

weather forecasting based on numerical models depends on all of the following except A) energy, B) fluid dynamics C) thermodynam
frez [133]
It would be letter A which is energy. The other three are used in weather forecasting due to the fact that the atmosphere is fluid and weather and climate is caused by uneven heat from the star in our solar system which is the Sun to the Earth in which heat transfer occurs
