1- The terrestrial lithosphere is composed almost of 80% by igneous rocks, they are also known as magmatic rocks and are formed at high temperatures due to magma solidification, they come from the superior mantle and terrestrial coast. Its texture is super resistant with significant hardness to obtain minerals and other derived materials. They can be divided into extrusive and intrusive.

2- Through experiments, Bowen has defined a sequence of mineral formation when a magma begins to cool. There are two types of magmatic differentiation defined by Bowen, the continuous series and the discontinuous series. In the continuous series the internal structure of the magma is not altered and all minerals have iron and magnesium, they are formed: aluminum, silica and sodium and calcium.

In the discontinuous series decreasing the temperature reacts the previously formed mineral with the existing liquid, and thus a new mineral with different internal structure and composition is formed. They are formed: olivine, pyroxena, amphibole and biotite.

PLEASE PLEASE PLEASE HELP ME OUT........​
Elena L [17]

I think the answer is D, the radiative zone because, energy generated by nuclear fusion in the core moves outward as electromagnetic radiation. in other words, Energy is in the core but it takes radioactive waves to make it reach earth.

I don't think it's A, B C, because,

the corona has to do with the light of the sun

gamma zone is an example of radiation

the core is the base of the energy, where it's all stored

radiative zone makes it reach earth

That would be the choice I would choose. I hope this helps you.

The sources of air masses occur only in low and high latitudes because
vlabodo [156]

Answer:

b. There is insufficient contrast in surface type (land vs. ocean) in the middle latitudes.

Explanation:

The sources of air masses can be produced or at very high latitudes because they can carry big amounts of air from the top of a mountain till the bottom by the differences of pressure and temperatures. This kind of air mass is called continental.

In the other hand, in a low latitude, the air coming from the sea, try to reach higher latitudes, again, by pressure and temperatures differences. These kind of air masses are called maritime.

Hope it was useful.

What is the Fermi paradox?
astra-53 [7]
Description The Fermi paradox, named after Italian-American physicist Enrico Fermi, is the apparent contradiction between the lack of evidence for extraterrestrial civilizations and various high estimates for their probability. Michael H. Hart formalized the basic points of the argument in a 1975 paper.

What would happen if Earth's magnetic<br> field disappeared?
lina2011 [118]

Answer:

What would happen if Earth suddenly lost its magnetic field. The most obvious effect is that we would get lost, since our compasses wouldn’t work. Less obvious is that without the magnetic field the solar wind would strip away ozone from Earth’s atmosphere and leave us exposed to ultraviolet radiation.
