satellite images Flashcards
satellite
a highly complex piece of technology which is positioned above Earth in space. sensors on the satellite collect information about Earth and send it back to satellite receiving stations on the ground. the information is used to make different kinds of satellite images.
satellite images
they are not photographs. satellite images are made from a collection of data obtained by sensors on the satellite. satellites send information to receiving centers on the ground. computers process this date and produce different images that we can view and interpret.
data
data is information
information from satellite images
satellite images provide a selection of information about Earth, such as weather conditions, soil erosion, land use patterns, water availability and vegetation cover. it is possible to use a series of satellite images to see how conditions have changed over time.
how satellite images are used
satellite images help scientists identify areas where there is water and vegetation, and if rocks contain valuable resources such as oil, iron and gas deposits, as well as providing information about approaching cloud patters and storms. all of these uses can take place from examining satellite images without people having to actually visit the areas in question.
common uses of satellites
weather forecasting.
weather satellites provide information about the position and types of clouds in the atmosphere, wind speeds, pressure differences and temperature . a weather satellite can supply regular information about conditions in the atmosphere change over a short time.
trained meteorologist
can interpret a weather satellite image and make informed predictions about what the weather will be like in different places. cloud patterns provide information about approaching rain or snow storms. this information can help people prepare for what could be a natural disaster.
