Why is coal so deep inside the earth?
Coal is formed from plant matter that gets buried and compressed over millions of years. As layers of sediment build up on top of the plant matter, the increasing pressure and heat cause the organic material to undergo biochemical changes, eventually transforming into coal. Over time, geological processes can bury these layers deeper inside the Earth's crust.
How does weight of a body vary inside the earth?
People are (so far) not able to get very deep inside the Earth, so there is not that much variation, however, the closer you get to the center of the Earth, the less you would weigh. At the exact center you would be weightless.
Are diamonds made from coal?
No, diamonds are not made from coal. While both coal and diamonds are made of carbon, the conditions required to create diamonds are much more intense and happen deep within the Earth's mantle. Coal forms through the decomposition of plant matter over millions of years.
Why are caves so dark?
Caves are dark because they are deep underground, away from sources of light. Light from the sun does not penetrate deep into the earth, so once you are inside a cave, there is no natural light source to illuminate it.
Is peat the first stage of coal?
It can be, but not all peat becomes coal, and not all coal began as peat. Peat forms on the Earth's surface, while coal has to form within rock layers deep in the Earth. Coal takes many thousands of years to form. Peat forms more quickly, but only at about 1 mm depth per year. So neither can be considered a renewable form of energy.
How do you you use the word coal in a sentence?
The older power plants used coal, but it polluted so much we try to use other methods.
What causes magma to form deep inside earth?
Magma is molten meaning liquid-like so it is able to move inside earth. The tectonic plates separate the earth and magma. This explains when the plates move earthquakes and volcanoes occur. Lava is not magma by the way! lava is hardened magma and magma is molten!
Would gneiss be more likely to form at shallow depths or at great depths where mountains are pushed up?
No , because it has to be deep inside the earth so it ca be pushed up.
Why do scientists study rocks in order to study the inside of the earth?
Types of rocks are inside the Earth, so scientists study them.
Where do faults occur on earth and why?
Faulting is a type of brittle deformation; rocks crack and then move along those cracks. Deep inside Earth rocks are hotter and softer, so they will deform in a ductile manner, stretching and flowing like taffy.
How does the composition of earth atmosphere differ from the composition of the atmosphere of the gas giant planet?
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
How does the composition of earth's atmosphere differ from the composition of the atmosphere of the gas giant planets?
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
