In the plate tectonics theory, the lithosphere is divided into ____.
NISA [10]

The right option is; B. 7 major plates and many smaller plates

In the plate tectonics theory, the lithosphere is divided into 7 major plates and many smaller plates.

The plate tectonics theory is a scientific theory that explains that the Earth's lithosphere which is the rigid outer layer of the earth is made up of seven large continental and ocean sized major plates and many minor smaller plates. The movements of the plates are relative to each other and it usually ranges from zero to 100 mm per year. The interactions of the plates along their boundaries are thought to be the primary cause of majority of the earth’s seismic and volcanic activity.

You are making an illustration of the life cycle of an average star and the life cycle of a massive star as part of a computer a
Leya [2.2K]

The average star cycle: nebula, protostar, main sequence, red giant, white dwarf. The massive star cycle:  nebula, protostar, main sequence, super red giant, supernova, black hole, neutron star.

The star cycle is the sequence of changes that a star undergoes throughout its existence.

<h3>The evolutive stages of an<u> average star</u> are </h3>

  • Nebula: Stars are born from the nebula that is the dust and gas particles condensation due to gravity effect in the interstellar clouds

  • Protostar:  It is a more advanced level of condensation.

  • Main sequence. Equilibrium between gravity and nuclear fusion helps the star keep stable as long as the fuel lasts. The two main types are

• <em>Orange dwarf</em><em>: </em>between the red dwarf and the yellow dwarf

• <em>Yellow dwarf:</em> Like the sun

  • Subgiant: occurs when orange and yellow dwarfs finish their main sequence and start to run out of fuel, expanding.

  • Red giant. After the subgiant stage, the star enters a giant phase. The star can reach a size of up to 100 times its current size.

  • White dwarf. When average-sized stars run out of fuel, the red giant begins to disintegrate, losing its outer layers and exposing its core, which will become a white dwarf.

<h3>The evolutive stages of a<u> </u><u>giant star</u><u> </u>are </h3>

  • Nebula

  • Protostar

  • Main sequence. There are two main types

• <em>Yellow supergiant</em>. Extremely short phase. Almost no stars are known to be in this stage. The star swells on its way to becoming a red supergiant.

• <em>Red supergiants</em> are the largest stars in volume, but not in mass.

  • Supernova. When fuel is over in the red supergiants, the gravitational collapse produces a violent explosion originating the supernova.

  • Neutron star. A celestial body that remains as a remnant after the explosion gives rise to a supernova.
