Satellites can detect radiation the Earth reflects from the sun and radiation the Earth emits.TrueFalse

What do satellites measure from the Earth-Atmosphere system? Visible light onlyElectromagnetic RadiationWater

Satellite remote sensing is the gathering of data from Earth’s surface using satellites which orbit around Earth. This remote sensing is done using two different methods: passive and active sensor systems.What is the difference between passive sensor systems and active sensor systems?aActive sensor systems emit their own radiation toward the target. Passive sensor systems detect naturally occurring radiation from a target. bActive sensor systems detect naturally emitted radiation from a target. Passive sensor systems detect naturally reflected radiation from a target.cPassive sensors reflect solar energy and direct it toward the target, which reflects this energy back. Active sensors absorb solar energy emitted by a target. dPassive sensors detect solar energy and can be used day or night. Active sensors emit electromagnetic radiation and can be used during daylight hours only.

Satellites can help us "see" light that is invisible to human eyes

Which is the satellite Terra able to do?A.Monitor seismic activity on the moonB.Monitor the movement of comets and meteoritesC.Monitor the orbit of MarsD.Monitor volcanic eruptions on EarthSUBMITarrow_backPREVIOUS
