The orientation rather than the angle of Earth's axis also changes over time, around in a complete circle over each 25,800 year cycle; this precession is the reason for the difference between a sidereal year and a. The inner core is extremely hot it is somewhere between 9000 and 13000 degrees Fahrenheit 5000 and 7000 degrees Celsius. Atmosphere Atmosphere Near the surface, Earth has an atmosphere that consists of 78 percent nitrogen, 21 percent oxygen, and 1 percent other gases such as argon, carbon dioxide and neon. Then I keeps going on like that. The average specific gravity of oceanic crustal rock is 2. The continental is made up of igneous rocks, and the oceanic crust is made up of sedimentary and basalt rocks. This last phenomenon is known as the : trace molecules within the atmosphere serve to capture emitted from the ground, thereby raising the average temperature.

Also, the ozone layer absorbs harmful rays from the Sun. So because the asthenosphere is less dense or lighter than the lithosphere is forces its way up to the top and foces the lithosphere down. When you finish the questions click on the Earth icon to return the program to the beginning. The inner core is 5000 to 7000 degrees hot. In the history of the Earth, has gone through long periods of expansion, occasionally punctuated by. Use questions to help you learn, Questions are a great way to guide you're learning, here are some of the questions I first had. As far as we know, such a magnetic reversal doesn't cause any harm to life on Earth, and a reversal is very unlikely to happen for at least another thousand years.

The most widely used analysis of Earth's atmosphere is into five layers. This is one of the three layers that is putting pressure on the inner core. The first layer is called the Crust and it is the thinnest layer of the Earth. But these convection currents effect the earth and the tectonic plates. How many layers are there? More recently, the name is sometimes simply given as Earth, by analogy with the names of the.

Magnetosphere Magnetosphere Our planet's rapid rotation and molten nickel-iron core give rise to a magnetic field, which the solar wind distorts into a teardrop shape in space. Beyond these, the thins out into the , where the geomagnetic fields interact with the. University of British Columbia, Okanagan. Even if the Sun were eternal and stable, 27% of the water in the modern oceans will descend to the in one billion years, due to reduced steam venting from mid-ocean ridges. Transition Zone : The depth of the transition zone isbetween 410 km and 660 km. It is a solid because of all the pressure from the other layers putting there weight onto this layer.

The Lower Mantle : The depth of the lower mantle ranges from 670 km to 2798 km. Estimates of the number of species on Earth today vary widely; most species have not been described. Earth's axis of rotation is tilted 23. The average density of the continental earth is 2. The combination of these processes recycles the back into the mantle. It stabilizes our planet's wobble, which has made the climate less variable over thousands of years. Just reading down the … table makes it worth the few moments it takes to surf on over.

Themantle can be further divided as follows: Upper Mantle:Lithosphere:The uppermost mantle consists of hard rock and is attached to thecrust and comprises the lithosphere. In the Northern Hemisphere, currently occurs around 21 December; is near 21 June, is around 20 March and is about 22 or 23 September. The height of the varies with latitude, ranging between 8 km 5 mi at the poles to 17 km 11 mi at the equator, with some variation resulting from weather and seasonal factors. Transition Zone: The depth of the transition zone is between 410 kmand 660 km. Unlike the outer core, the inner core exists in a solid form due to the increased pressure which solidifies iron in the layer. This layer should not be confused with the.
