Techniques Used to Learn About the Earth
Many different techinques are used by scientists to learn about our
earth today. They have devices that can tell you what kind of weather
we are going to get and when we are going to get it. They have tools
that can analyze something and tell you exactly what it is.
Tools and
devices are used to detect earthquakes, or valcanic eruptions so people
will have a good idea in when these things will occur. Satelites sent
into space play a big role in learning about the earth, because they can do
so many things and see way more because they are s high up. Tools
are based upon the latest technologies. For example, element analysis,
which solves confussing computer modeling problems by breaking them
down into smaller pieces to make it easier to fix. Elements are many
of measurements on
how the earths crust changes because of movement
of the really big tectonic plates earths landmasses are on. Measurements
are gathered through both the ground and space based techniques. This
has global positioning system and interferometric synthetic aperture radar,
which measure motions that deal with plate tectonics and the earthquake
quake cycle. Geographic visualizations use data and computerized tools
to help us see, explore and learn about the Earth in ways that scientists
never have beofore. There are many types of geographic visualizations,
like printed pictures, to drawings showing change over time, and
computerized maps that let us see 3-D virtual environments. Regardless
of format, geographic visualizations are a big help for exploring and
discovering things that havent been discovered.
