From the deepest to the surface, what are the parts of the earth’s interior?
a)crust→mantle→core
b)core→crust→mantle
c) core→mantle→crust
d) mantle→crust→core

C) core→mantle→crust

Explanation:

From the deepest to the surface, Earth's interior is divided into three layers:

- Core: the core is the Earth's innest layer. It has very high temperatures (around 5000 degrees) and it extends from the centre up to a depth of about 2,900 km below the Earth's surface. The main elements present in the core are iron and nickel. It is further divided into two regions, called inner core and outer core: the main difference between the two is that while the inner core is solid, the outer core is liquid.

- Mantle: located between the core and the crust, the mantle extends up to about 10-100 km below the surface (depending on the location). It is the thickest layer. It mainly consists of silicate rocks; these rocks are solid but given the high pressures and temperatures, these rocks slowly move (on geological timescale) as they were a viscous fluid. These movement creates convective currents that drives the plate tectonics in the crust.

- Crust: the outermost layer of Earth, its thickness spans between 5 and 70 km depending on the location. It is further divided into continental crust, which is thicker and composed of silicate rocks (such as granite), lying under continents, and oceanic crust, which is thinner and mainly consists of basalt, lying under the oceans.

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like . (i crazy)

most famous scientist who contributed to this physics are:

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!
