Explanation / Answer

37) Dextral

right-lateral motion are also known as dextral faults. Each is defined by the direction of movement of the ground as would be seen by an observer on the opposite side of the fault. A special class of strike-slip fault is the transform fault, when it forms a plate boundary.

38) Alluvial Fan

Alluvial fan: An alluvial fanis a fanshapeddeposit formedwhere a fast flowing stream flattens, slows, and spreads typically at the exit of a canyon onto a flatter plain.

39) Terminal Morains

A terminal moraine, also called end moraine, is a type of moraine that forms at the snout (edge) of a glacier, marking its maximum advance. At this point, debris that has accumulated by plucking and abrasion, and has been pushed by the front edge of the ice, is driven no further and instead is dumped in a heap.

40) Iceland

The Mid-Atlantic Ridge is where seafloor spreading takes place in the middle of the Atlantic Ocean. It is part of a world-wide system of mid-ocean ridges. These ridges make up the longest mountain range in the world, all underwater except for short stretches like Iceland.
