Question

explain about effect of nitrogen gas present in atmosphere?? and also explain about the earth crusts? ​

Answer 1

Answer:

The effect of nitrogen gas present in the atmosphere on oxygen. ... Due to which the amount of the oxygen getting lesser and nitrogen is at its stable ratio. On the other hand, when nitrogen forms its compound which is a nitrous oxide that is as a greenhouse gas and promotes global warming

“Crust” describes the outermost shell of a terrestrial planet. Earth's crust is generally divided into older, thicker continental crust and younger, denser oceanic crust. The dynamic geology of Earth's crust is informed by plate tectonics. “Crust” describes the outermost shell of a terrestrial planet.

$\huge{Earth's\ crust:-}$

》In geology, a crust is the outermost layer of a planet.

• The crust of the Earth is composed of a great variety of igneous, metamorphic, and sedimentary rocks.

• The crust is underlain by the mantle.

• The upper part of the mantle is composed mostly of peridotite, a rock denser than rocks common in the overlying crust.

• The boundary between the crust and mantle is conventionally placed at the Mohorovicic discontinuity, a boundary defined by a contrast in seismic velocity.

• Earth's crust occupies less than 1% of Earth's volume.

• The oceanic crust of the Earth is different from its continental crust.

• The oceanic crust is 5 km (3 mi) to 10 km (6 mi) thick and is composed primarily of basalt, diabase, and gabbro.

• The continental crust is typically from 30 km (20 mi) to 50 km (30 mi) thick, and it is mostly composed of less dense rocks than is the oceanic crust.

》Some of these less dense rocks, such as granite, are common in the continental crust but rare to absent in the oceanic crust.
