Answer:

UV radiation, extreme temperatures and low density of gas.

Explanation:

The thermometer is a layer of the earth that is directly found over the mesosphere and is has an atmosphere of the UV rays and the photoionization of the molecules that leads to the creation of the ionosphere. Here the temperatures are severed and vary with the solar activity and despite the high temperature it has a low density of the gas.

The presence of the Thermospheric storms that occur in the high altitudes is a giant storm and is due to the impulsive form of disturbance, with the respect to the magnetosphere disturbance.

Answer:

Barycentre of planet lies at 1.068 radii.

Explanation:

Jupiter is a Jovian planet and has mas of all rest of the planet combined and is 2.5 times as massive as other planet s and has a mass as similar to that of a brown dwarf.

Jupiter lies about 1.068 solar radii from the Sun's center and scientists also suggest that Jupiter mass is shrinking due to the atmospheric variation by the sun.

Relative Age- E

Law of Superposition- C

Intrusion- D

Absolute Age- A

Index Fossils- F

Explanation:

Fault- A fault generally refers to the fracture as a result of which either the hanging wall goes up or down with respect to the footwall. it takes place either due to compressional or extensional stress. In simple terms, it is a break that occurs in the earth’s crust.

Extrusion- These are the consolidated rocks that are formed when magma comes out to the surface forming extrusive rocks. For example, Basalt and Rhyolite.

Unconformity- It is defined as the period of non-deposition. It occurs when the rocks surfaces are eroded extensively. These are the surfaces where the much older rock meets geologically younger rocks.

Relative age- When the age of any rock is compared with the age of different rocks then, the relative age of the rock is obtained. It is extensively used for the calculation of the age of rocks from any sedimentary sequence.

Law of Superposition- This law enables us to evaluate the relative ages of two or more rocks as it depicts the younger rocks that are deposited on the apex and the older rocks at the bottom of a sequence.

Intrusion- These are the rocks that form due to the crystallization and solidification of magma beneath the earth's surface. For example, granite and gabbro.

Absolute age- This refers to the total amount of time (in terms of years) that a rock has formed. These rocks are formed from the deposition, compaction, and lithification of sediments in a sedimentary environment.

Index fossils- These are the fossils that were present for a shorter period of time and have a wide geographical distribution and were mostly used by the geologists in order to match the rock layers.
