NASA Adds Up Hurricane Sandy's Rainfall from Space
Read All About It!
NASA's Tropical Rainfall Measuring Mission, or TRMM, satellite acts as a rain gauge in space as it orbits Earth's tropics. As TRMM flew over Hurricane Sandy since its birth on Oct. 21, it was gathering data that has now been mapped to show how much rain the storm dropped along the U.S. eastern seaboard.
As Apollo 8 orbited the Moon on
Christmas Eve, 1968, the astronauts remarked at how beautiful our home planet looked hanging there in the vastness of space.
Almost to a man, the astronauts were glad they got to go, but always kept an eye turned back toward home.
So, this is the story of our home planet, a world that is unique, fragile, and vulnerable.
We have seen that the Nebular Hypothesis Theory assumes that our Solar System was formed from a flat, rotating disk with the protosun at the center.
The inner planets begin to form from metallic and rocky substances that can only crystallize at higher temperatures.
In the colder outer Solar System, the larger planets began forming from gases and ices, such as H2O, CO2,NH3, CH4, and other compounds.
Here in the inner Solar System, in the planet that would one day be known as Earth, iron and nickel melted and sank to form the metallic core, while lighter, rocky materials rose to form the upper mantle and Earth’s crust.
Flattening and spinning. Gravity, shock waves, condensing, “dust bunny” analogy.
Origin of Earth - The Nebular Hypothesis
Formation of Earth’s Layered Structure
the solid matter of the Earth, as distinct from the seas, plants, animals, and surrounding atmosphere
The ocean is the most prominent feature of the hydrosphere, as it covers nearly 71% of Earth’s surface and contains about 97% of Earth’s water
The hydrosphere also includes fresh water found in streams, lakes, and glaciers, as well as that found underground.
Hydrosphere the Earth.
The cryosphere is very important to our understanding of climate change.
This is the frozen part of the Earth's surface, including the polar ice caps, continental ice sheets, glaciers, sea ice, and permafrost.
Earth’s Biosphereincludes all life, and is concentrated near the surface in a zone that extends from the ocean floor upward for several kilometers into the atmosphere.
The lithosphere is the rigid outer layer of solid Earth that can be broken.
It includes the crust and the uppermost mantle, which constitute the hard and rigid outer layer of the Earth.
The pedosphere is the uppermost part of the lithosphere that chemically reacts to the atmosphere, hydrosphere and biosphere through the soil forming process.
