The grassland of North America is a "steppe climate" in fact in Russia grasslands are called Steppes. This climate makes us prone to WEATHER from high pressures and low pressures meeting up and not liking each other very much - Lightning, Hail, Tornados, Floods, and in the northern parts Blizzards. Basically Winds and Clouds are what we watch and monitor - beautiful, dangerous, and can go from benign to ferocious in the blink of an eye. Weather can kill and weather can be a salvation. It depends on the whims of pressure.
New Zealand has had a three decade anti-nuclear campaign so it's safe to assume they are.
Potential Energy
The potential energy gained is 43750 J
Explanation:
Potential energy is the energy by virtue of an object's position relative to the ground ie, the height of the other object.
For example, an object has more potential energy when it is on top of a two-story building than it does resting on the ground. That's because the object's relative position to the Earth gives it more energy.
Potential Energy is defined as
Potential energy = Mass * height
Given Mass M = 1250 N
Given height h = 35 m
So the potential energy = 1250 * 35 = 43750 J
Thus the potential energy is 43750 J
Covers one half of the earth is not a characteristic because deserts simply do not cover half the earth
