Final answer:
Scientists use remote sensing technology to acquire data about the earth's surface and analyze changes in temperature.
Step-by-step explanation:
Scientists use remote sensing technology to acquire data about the earth's surface through aerial photographs taken from airplanes or images created from satellites orbiting the earth. This technology allows scientists to identify and understand landscapes, determine land use, and analyze changes on the earth's surface caused by natural or human forces.
For example, scientists can use remote sensing to predict changes in temperature by analyzing previous and current data such as the dimensions and locations of glaciers, water levels in lakes, rivers, and oceans, and the number of annual rings in trees.
