Earth Sciences is the study of the Earth in terms of Geography, Geology, Geophysics, etc. It combines the use of Sciences such as Biology, Chemistry, Physics and Mathematics to understand the Earth System.
Asked in Astronomy, Earth Sciences, Seasons
What causes the seasons on Earth?
This is a more complex answer than most might think. Climate (long term weather) and climate change are a basic factor of 3 main things Obliquity (axial tilt) Precession Rotation (elliptical eccentricity,) They are also referred to as Milankovitch cycles named for the Serbian scientist that theorized and later proved his idea of cyclical climate changes with 26k 41k and 100k events which later were mathematically shown to coincide almost exactly with earths climate history. The...

What is the rock cycle song?
SEDIMENTARY rock Has been formed in layers Often found near water sources With fossils from decayers Then there's IGNEOUS rock Here since Earth was born Molten Lava, cooled and hardened That's how it is formed These two types of rocks Can also be transformed With pressure, heat and chemicals METAMORPHIC they'll become (sung to the tune of row row row your boat) (=**=) (<cat lol) ...
What are the parallels halfway between the equator and the poles?
Answer #1: I believe you mean the Tropics of Cancer and Capricorn, but they are not half way (ie 45 degrees north and south) they are 23° 26′ 16″ N and S respectively. ================================ Answer #2: I believe you mean the parallels halfway between the equator and the poles, since that's the way you worded the question. They are the parallels of 45° North latitude and 45° South latitude. ...
Asked in Earth Sciences, Erosion and Weathering
How do you stop gravity erosion?
There are a number of different ways in which you could potentially prevent gravity-related erosion, but you could also take measures to prevent damage from the erosion too. To prevent the erosion in the first place, you could anchor the ground/boulders in place. In addition, you could totally remove particularly difficult boulders or overhangs, although this is more expensive. Prevention is always more expensive than protection. To protect property from mass movement (landslide etc.), if the property is on top of the precarious...
Asked in Earth Sciences, Geophysics
Where does Earth's water originally come from?
The Short Answer: Some of it was here when the earth was made (but locked into the rocks as hydrates ... much of that released as the Earth became molten.) And some came from comets and other ice particles that have bombarded the Earth since it was formed. No one knows which part was the major contributor. In more depth...: At some early point in time (after the moon) the Earth was a hot, glowing ball which would have out-gassed fairly completely. Hydrogen is light...
What is Mars made of?
Mars is made of rock and iron oxides. It's surface is covered in mountains, volcanoes, valleys, ice caps and dried up river beds. Mars is also very dry like a desert. It is also red because of the iron oxide in the pulverized rock dust. Mars is a planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, deserts and polar ice caps of Earth. ...

What causes the Earths seasons?
Four Seasons, Winter. Seasons are a subdivision of a year. The Earth's rotation axis is tilted by 23.4392794383 degrees with respect to the, at different times of a variation in the 180 - 270 deg (mn), longitudes 270 - 360 deg (Winter). The Sun true longitude (Lsun) is derived from Sun mean longitude (Lmean) and Earth mean anomaly (ME). For any input through many Sun true Longitude (Lsun) for the input year 1013 : Year = 2013, Start : UT year =...

What would happen if you put salt water in the sun?
Theoretically, if you were to physically go to the Sun and pour a bucket of salt water on the Sun, the bucket of water would simply evaporate, along with you can the bucket itself. However some may say the Sun is a giant nuclear reactor. If you were to input a salt water compound large enough to withstand the heat of the Sun (which is improbably to say the least), the hydrogen and oxygen atoms would split apart from each other....
Why satellites are placed at an altitude of 36000 km is there any reason for such an long altitude pls answer thanks in advance?
The closer to the Earth, the faster the orbit; this is basic math, as determined Johannes Kepler centuries ago. The higher the orbit, the slower the satellite goes. IN 1947, science fiction writer Arthur C. Clarke wrote an article and a story based on the curious coincidence that if a satellite were placed in an equatorial orbit 23,000 miles (or 36,000 km) up, the satellite would orbit the Earth at precisely the speed that the Earth itself turns. The satellite would appear...

How much of the Aral Sea has dried up?

Asked in Physics, Earth Sciences, Magnetism
When does the magnetic field in rocks form?
Magnetism is a property of certain materials, usually metals, that have an electric dipole on the molecular scale. A dipole is a significant separation between the positive and negative charges in the molecule. Since electrons and protons have spin, and moving electrical charges generate megnetic fields, the dipole generates a net magnetic field. If enough dipoles are oriented in the same direction the body has a net magnetic field. The dipoles can align when sitting in a permanent magnetic field for a long...
