read the passage.\nfinding the invisible\nall over the planet, ancient tombs and temples lie hidden from view. so how do archaeologists know where to begin digging? thanks to satellites, that question is becoming easier to answer. in the pioneering field of satellite archaeology, satellites four hundred miles above earth can identify structures buried under soil, covered by modern construction, or obscured by forests. for example, mud bricks used by ancient egyptians are more dense than soil, and the differences are detected by the satellites. advanced computer programs map buried settlements and distinguish them from water, vegetation, and farmland. sarah parcak, a pioneer in the field, says of the technology, \it allows you to literally strip away vegetation and see entire cities beneath the rain forest canopy. this is the unbelievable future of archaeology.\\nwhat is the main, or central, idea of the passage?\narchaeologists are uncovering ancient hidden structures by using satellite imagery.\nsatellite archaeology is a rapidly expanding new scientific field.\narchaeologists must determine where ancient structures are buried before they can begin excavating them.

Answer

Brief Explanations:

The passage starts by asking how archaeologists find hidden ancient structures and then details how satellite archaeology helps. It gives examples of satellite - based detection and quotes an expert. The overall focus is on archaeologists using satellite imagery to uncover hidden structures.

Answer:

Archaeologists are uncovering ancient hidden structures by using satellite imagery.
