Explanation:
convergent plate boundaries
Natural phenomena such as earthquakes, mountain formation, and volcanoes occur at plate boundaries. Mountains are usually formed at what are called convergent plate boundaries, meaning a boundary at which two plates are moving towards one another. This type of boundary eventu
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>
They have a characteristic U shape, with steep, straight sides and a flat or rounded bottom (by contrast, valleys carved by rivers tend to be V-shaped in cross-section). Glaciated valleys are formed when a glacier travels across and down a slope, carving the valley by the action of scouring.
