Answer the following question given this paragraph: Once a sand dune forms, it may slowly migrate over the land. The wind moves grains of sand up the gently sloping side of the dune. This is done by saltation. When the sand grains reach the top of the dune, they slip down the steeper side. The grains are pulled by gravity. The constant movement of sand up and over the dune causes the dune to move along the ground. It always moves in the same direction that the wind usually blows. Can you explain why?. Q: The migration of what familiar coastal landform involves saltation and gravity? A:
OPTIONS:
- volcanos
- lakes
- rivers
- sand dunes

Answer: sand dunes

input with options: Answer the following question given this paragraph: Metamorphism. This long word means "to change form. " A rock undergoes metamorphism if it is exposed to extreme heat and pressure within the crust. With metamorphism, the rock does not melt all the way. The rock changes due to heat and pressure. A metamorphic rock may have a new mineral composition and/or texture. Q: What is a rock exposed to if it's undergoing metamorphism? A:
OPTIONS:
- humidity and pressure
- gravity and precipitation
- time and energy
- heat and pressure
output:
heat and pressure
