Main Theory About Earth

About Earth

 

 

We have come so far in our search for knowledge that we have about Earth. How much do we know about our planet? It seems like it should be a simple question but the more we learn about our planet, the more questions we get. Do we know anything about Earth’s atmosphere? How about its magnetic field? How about the composition of our planet?

Did you know about Earth’s atmosphere? One scientist uses it as a model for studying the atmosphere of other planets. About 99.9% of Earth is covered by air. Scientists use this to study the composition of other worlds in the solar system and to create models of gases that exist beyond our atmosphere. About Earth’s magnetic field, many scientists use it to study the composition of comets and to study the effects of collisions between comets and planets.

Have you ever heard about Earth’s hydrology? Have you ever heard about Earth’s climate? Does our solar system or our galaxy have any significant oceans? Maybe you are even aware of our atmosphere, but what do scientists know about hydrology, climate and meteorology?

Do you know what plate tectonics is? How about hydrology? Does our planet have an atmosphere or any liquid water? Are there volcanoes on our planet? The Atmosphere is mostly made up of water vapor and clouds. Do scientists study the effects of plate tectonics and the formation of planets and comets in our solar system and around other stars?

Do you know about solar astronomy? How about the moon and the stars? Do scientists observe and study these celestial bodies through satellites, space telescopes and ground-based telescopes? Are there many dark spots on the moon that were caused by collisions with other small icy bodies or comets?

Have you heard of exotic planets and their moons? Astronomy clubs have discussed these lately and there have been many proposals for such. There have also been proposals for finding other celestial bodies beyond the earth’s orbit. How about comets and dwarf planets? Do astronomers study these planetary objects to learn more about our solar system and how it formed? Do they study their atmospheres and composition to try to determine if there are other planetary bodies out there like our own that have similar compositions?

Do scientists study weather on earth? Do they study the “greenhouse effect” which is warming up the planet and causing glaciers to melt and other kinds of weather extremes? Is there a connection between global warming and the number of earthquakes and volcanoes on our planet? These are all important questions that scientists are trying to answer especially if they can find out how humans are influencing climate on the earth and how that may impact future generations.

Why aren’t we studying more about the earth? Why aren’t we studying more about the big-bang theory? Why aren’t we studying more about space travel? Scientists working at NASA, JPL and other space related organizations are doing a great job but they don’t have a lot of space, they don’t have a very large budget, and they don’t have a way to get people to actually witness all the amazing things they are doing in space.

Do you know what the major planets in our solar system are making contribute to our earth’s gravity? Do you know what the other planets in our solar system are making contribute to our gravity? How about the moons of planets? The inner and outer atmosphere of a planet, can it be determined by observing the planet and the moon? The planets spin around their axis and the moon to orbit the planet, it’s not so complicated when you put two things together

Does the earth spin or is it taken oblate? How about the satellites circling the earth or do they spin. Can scientists use the Doppler effect to show the earth and moon rotation. Do the inner planets like Jupiter and Saturn wobble and if so why and how.

Do you know what makes up the atmospheres of planets? We know the earth’s atmosphere is primarily made of water vapor, carbon dioxide, and nitrogen. And the earth’s oceans are mostly H2O (water vapor and oxygen). Now some like to speculate that the atmosphere forms a cloud top, where clouds occur, this cloud tops allows infrared radiation to bounce off the atmosphere creating the clouds. So this would imply that our earth is warm because of the ocean absorbing infrared radiation and warming up the planet, and by implication the atmosphere of the planet is transparent, thus allowing infrared radiation to bounce back, thus cooling the planet down.
