Read the passage Finding the Invisible All 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 What is the main idea of the passage Satellite archaeology is a rapidly expanding new scientific field Archaeologists are uncovering ancient hidden structures by using satellite imagery
