Convection currents occur in the MANTLE. The mantle is the second layer of the earth after the crust. The mantle is approximately 2900 km thick. Convection currents are triggered or fueled by the heat from the Earth's core.
The part of the mantle closest to the core gets heated. It then becomes less dense than the layers above so it rises. When this rising plume interacts with the crust it cools and becomes more dense than the layers below and so it sinks and this circular motion continues to form convection currents.
The answer is C because they show territory gained through the years
Both Australia and Fiji are located to the South of the Equator, and quite close to each other. Fiji is located more to the North than New Zealand, but it is, just like New Zealand, to the west of Australia, so the statement that Australia is to the West of Fiji is false!
Answer:
is USA
Explanation:
I just but the best way to get right u ask or your teacher
If the semicircle is on the 29 side:
<span>2(19) + 29 + 29pi/2 = 67 + 14.5pi </span>
<span>This is because the radius is equal to 1/2 the diameter and the perimeter of a semicircle is radius*pi. The 2 19's come from the rectangle part of the garden and the other 29 comes from the side opposite the semicircle. </span>
<span>If the semicircle is on the 19 side: </span>
<span>2(29) + 19 + 19pi/2 = 77 + 9.5pi </span>
<span>You simply switch the 19 and 29 values.</span>
