SOLAR SYSTEM

Detailed explanation-1: -To collect data at higher altitudes, scientists turn to satellites. In the 1960s, NASA launched TIROS I, the nation’s first weather satellite. Today, weather satellites, which continuously circle our planet hundreds of kilometers above its surface, are one of the most effective tools for studying Earth.

Detailed explanation-2: -Satellites measure the concentration of particles (aerosols) in the atmosphere by observing how much light reaches the surface of the Earth and how much is reflected off the aerosols. The measurement is called aerosol optical depth or aerosol optical thickness.

Detailed explanation-3: -Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic network. The earliest “seismoscope” was invented by the Chinese philosopher Chang Heng in A.D. 132.

Detailed explanation-4: -A space probe is an unpiloted, unmanned device sent to explore space and gather scientific information.

Detailed explanation-5: -Meteorologists are observers and researchers. They note the physical conditions of the atmosphere above them, and they study maps, satellite data, and radar information. They also compare various kinds of weather data from local, regional, and global sources.
