Water: it can wash things out. depending on the strength it can reform islands or other things.
Wind: it can blow around fine particles of the earth, overtime it creates a new shape to the land.
Sand: when blown in a desert the sand mounds will change shape, however it can erode rocks too, its a slow process though.
Fire: it obviously burns things down. when burning trees fall if they don't burn completely they will remain. over time new plant life will grow over the tree forming a new shape.
I think its ideology (D) but i am not quite sure …
The three classifications of magma are mainly identified using their silica composition. Basaltic magma has the lowest silica content of 45-55% by weight. This makes it the least viscous and least explosive. Andesitic magma has 55-65% , making it more explosive and viscous. Rhyolitic magma has 65-75% silica, and is the most viscous and catastrophic.

may be the way the wind blew? or that that is the way the sand is deposited
