of the Moon’s origin? The currently accepted hypothesis for the Moon’s origin--which is supported by chemical analysis of Moon rocks--is that it began as part of Earth but was blown off when the early Earth was struck by a Mars-sized early planet (retroactively named Theia). Huge amounts of debris were ejected into orbit around the Earth‚ where most of it coalesced into the Moon. The other moons in the solar system have different origins. The small ones are mostly captured asteroids‚ I think‚ while

The crust is primarily made of granite and basalt while the mantle beneath is made of peridotite. More about all that below. How We Know the Earth Has a Crust Just a century ago‚ we didn’t know the Earth has a crust. Until the 1900s all we knew was that our planet wobbles in relation to the sky as if it had a large‚ dense core. Astronomical observations

the organism. Q: Based on the conditions of early Earth‚ what conclusion can you draw about the amount of anaerobic respiration that was occurring at Earth’s beginning? Explain your answer. A: The atmosphere of early Earth was made up with almost of different nitrogen gases‚ water vapor and carbon dioxide. There wasn’t any pure oxygen or I should say there wasn’t any breathable oxygen in the air in those days. The first form on earth had to develop in the absence of oxygen using the anaerobic

Earth Day Founded in 1970 as a day of education about environmental issues‚ Earth Day is now a globally celebrated holiday that is sometimes extended into Earth Week‚ a full seven days of events focused on green awareness. The brainchild of Senator Gaylord Nelson and inspired by the antiwar protests of the late 1960s‚ Earth Day was originally aimed at creating a mass environmental movement. It began as a "national teach-in on the environment" and was held on April 22 to maximize the number of
