Question

an underground porous rock layer often saturated with water in the form of streams is called a(n) ____ a) aquifer b) continental shelf c) fault line d) aqueduct ____ is freshwater filtered through soil that originally came from rainfall and melted snow. a) precipitation b) groundwater c) runoff d) condensation

Explanation:

First Question (about underground porous rock layer saturated with water):

An aquifer is defined as an underground porous rock layer (or sediment layer) that is often saturated with water, which can flow in the form of streams within it. A continental shelf is a submerged part of a continent, a fault line is a fracture in the Earth's crust, and an aqueduct is a man - made structure to carry water. So the correct option is A.

Groundwater is the freshwater that has filtered through the soil. Precipitation is the process of water falling from the atmosphere (like rain, snow). Runoff is the water that flows over the land surface. Condensation is the process of water vapor turning into liquid water. So the water that filters through the soil, originally from rainfall and melted snow, is groundwater. The correct option is B.

Answer:

A. aquifer
