Name the layer of the atmosphere where jets fly through and contains ozone layer

Geography

alexandr1967 [171]3 years ago

Answer:

Stratosphere

Explanation:

The layer through which the jets are flying is the stratosphere. This atmospheric layer is the second layer by distance from the lithosphere, being above the troposphere, and bellow the mesosphere. It is a layer where the gasses are much more dispersed than in the troposphere, thus making it less dense. On the other hand, it has air movements that are are relatively strong and constant, which is something that is very useful for flight, thus the jets are flying in this layer in order to have easier and cheaper flight. What makes this layer very important and marking is the layer in itself, the ozone layer. This layer is crucial for the survival of the living organisms on the planet, as this is the layer that stops and absorbs the majority of the UV rays from the sun, thus not allowing them to reach the surface at their full potential, stopping them to fry alive the living organisms.

Which of the following geological features can form at a subduction zone? A. Volcanism and mountain ranges B. Mid-ocean ridges C
Alecsey [184]

Geological features that can formed at a subduction zone is Mid-ocean ridges

<u> Explanation:</u>

Mountains on land are called mountains, which are formed due to tectonic events as learnt in books. But what about mountains underwater are known as ridges. Sometimes even as mid-ocean ridges. These are ridges which are underwater and formed with tectonic plates.

There are two processes come across in them called ridge-push and slab-pull. Under the seduction zone, slab pull is the process that comes into motion. Under this Weight of the heavy tectonic plates are being pulled in the process. Apart from mid-ocean ridge no other geological feature can be formed at the seduction zone.

1. Can a rock that has undergone metamorphism turn into a sedimentary rock? If so, how? If not, why not?
satela [25.4K]

1. Yes

The sedimentary rocks are the rocks that form the last, and they form from a parent material from the igneous and metamorphic rocks. When we have a metamorphic rock, it means that we have a rock that has formed deeper into the ground, when it has been exposed to higher temperatures and pressure. Over time though, with the geological activities, this metamorphic rock can be pushed on the surface. Once this happens, the metamorphic rock will be exposed to erosion and weathering, thus it will start to get broken apart, and sediments will form from it. If the conditions are right, then those sediments can merge back together, to create a softer, new type of rock, a sedimentary rock.

2. Crystallization

The hot molten magma is the one that forms the igneous rocks, which are the basis for the formation of the other two types of rocks, the metamorphic and sedimentary rocks. In order for the magma to become rock, in needs to cool off, and this happens both on the surface and inside the crust. As the magma cools off, it starts to undergo a process of crystallization, which basically means that it solidifies and crystals are formed. Depending on the location of the crystallization, as well as the speed of it, different types of igneous rocks can be formed.

3. warm and humid

The carbonate rocks are rocks that are very high in carbon content. This type of rocks forms when there has been very large depositions of biomass, mostly by wood, which managed to merge with sediments, and under particular temperature and pressure created a rock. The carbonate rocks can be found exclusively on places that have had warm and humid climate in the past, as the enormous amounts of wooden mass required for this rocks to form can only be found in places like that, as well as the proper conditions that the wooden mass is quickly covered with mud from the outside influences.

4. In all sections of the rock cycle

The gemstones are a group of rocks that can be igneous, metamorphic, or sedimentary. There is a very big variety among them, and that is largely attributed to the fact that these rocks form in the mantle, deep into the crust, close to the surface, and on the surface. It is not just that these rocks have very big variety, but they also differ a lot in which section of the rock cycle do they form, as they can form in pretty much every section of the rock cycle, depending on the type of gemstone. In the gemstone category we have the diamond, quartz, opal, ruby, sapphire etc.

5. Even though the Big Island of Hawaii is one million years old, it is almost impossible to set foot on rocks of that age, but in general the rocks on the surface are not older than 1,000 years. The main reason for this is that the island has an active volcano. Not just that the volcano is active, but it is also a type of volcano that has calm eruptions with enormous amounts of lava flows. The lava flows constantly cover the rocks that already existed, and as it cools of and crystallizes, it forms a new layer of rocks. This process has been going on continuously, so the rocks on the surface tend to be very young because they are formed from the more recent lava flows.

Ccording to the theory plate tectonics, the Earth's crust is broken into about 12 plates that float on hotter, softer rocks in t
LiRa [457]

The correct answer is - B) convection currents in the mantle.

There's multiple tectonic plates on the surface on the planet, around 17 from what is known so far, but as the scientific methods are developing there might be few more discovered in the years to come.

These plates are all moving, only few cm per year, but on the long term it influences and changes everything on the surface on the Earth.

The movement of the plates is the result of the convection currents in the mantle layer beneath. These convection currents are essentially the combination of the high temperatures, high pressures, and viscous metals, and they managed to break up the crust on the surface, and with its push force, they are slowly moving the plates.

With the movement of the plates and their collisions and moving away, lots of earthquakes and volcanoes are appearing all over the plate boundaries.
