(The Birth and Evolution of the Earth; Earth’s Spheres)
List three things that the Earth has but the Moon does not have.
Any remediations that you want to go on this six-weeks must be done by Friday!
We will have a Quiz tomorrow!
William Souza has caught not just two, but three birds with one stone with this photo he took from Sao Paolo, Brazil. William captured this photo of the Crescent Moon, Pleiades and Mercury on April 26, 2009.Astrophoto
The Nebular Hypothesis assumes a flat, disk shape with the protosun (pre-Sun) at the center.
The inner planets begin to form from metallic and rocky substances.
The larger outer planets began forming from fragments of ices (H2O, CO2,and other compounds.)
Iron and nickel melted and sank to form the metallic core while rocky material rose to form the mantle and Earth’s crust.
Flattening and spinning. Gravity, shock waves, condensing, “dust bunny” analogy.

Unique the Earth.
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.
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 biosphere includes 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.
