Check all of the following mining methods which would most likely be used to mine salt.

• solution mining

• open-pit mining

• solar evaporation

• smelting

In longwall mining,

• a network of entries is cut into seams of ore deposits

• ore is mined downward, layer by layer

• a shearer is moved back and forth across the face of the seam

• hot water is injected into the ore to dissolve the ore, and then air bubbles lift the ore to the surface

Open pits called _______ are used to mine stone and gravel.

• overburdens

• cyanide heaps

• solar evaporation ponds

• quarries

_____________ often form at bends in a river where the water flows more slowly and heavier materials are likely to settle out.

• Dredges

• Placer deposits

• Seams

• Fans
