Mostly with cell phones and GPS
weather forecasting
and more TV channels than you'll ever look at.
Weather forecasting and telecommunication have improved
Atmosphere.
Mars is much smaller, cannot sustain life, is much colder and has 2 satellites.
The Earth underwent geological processes and life on Earth underwent evolutionary processes and the two are inextricably linked. Life terraformed Earth.
the satellites have found life on mars
is there life other than ours? are there any other earth like planets in the universe
Satellites increased the speed of global communications.
Global Positioning Systems (GPS) use trigonometry. There are a number of satellites orbiting the earth. The GPS uses the time signals sent by these satellites to establish the distance to the satellites. Trigonometry is then used to find the location of the GPS unit.
Every satellite is different, the biggest factor that limits the life of satellites is fuel used to maintain the orbit.
For one thing, they make the clocks that go in GPS satellites advance a little bit slower than normal so that when the satellites are orbiting the earth at tens of thousands of miles per hour the clocks seem to be in sync with our clocks here on the earth's surface.
Plate tectonic processes changed Earth's surface but also changed Earth's climate, too. Many species of coral did not adapt to the cooler climate.
New government, Wars have settled, No dinosaurs, etc.
