which of the following protects earth's atmosphere from solar wind
a.hydrogen atoms
b. radiative Zone
c.magnetosphere
d.convection currents
c. magnetosphere
The correct answer is c. magnetosphere.
The magnetosphere is a protective shield around the Earth that is created by its magnetic field. It helps to protect the Earth's atmosphere from the harmful effects of solar wind. Solar wind is a stream of charged particles released by the Sun and can cause damage to the Earth's atmosphere if not protected.
Hydrogen atoms, radiative zone, and convection currents do not directly protect the Earth's atmosphere from solar wind. Hydrogen atoms make up a part of the Earth's atmosphere. The radiative zone is a layer in the interior of the Sun where energy is transported by radiation. Convection currents are movements of fluid material caused by temperature differences. While these factors may play a role in the dynamics of the Earth's atmosphere and climate, they do not provide direct protection from solar wind.
The correct answer is c. magnetosphere. The magnetosphere is a region around Earth that is created by its magnetic field. It acts as a protective shield against solar wind, which is a stream of charged particles released by the Sun.
To derive this answer, we can eliminate the other options and explain why they are not the correct answers:
a. Hydrogen atoms: Hydrogen atoms alone do not protect Earth's atmosphere from solar wind. While hydrogen is the most abundant element in the universe, it plays a different role in the Earth's atmosphere. Hydrogen atoms are mainly present in the upper layers of the atmosphere and contribute to processes like the ozone layer formation and atmospheric chemistry.
b. Radiative Zone: The radiative zone is a region inside the Sun, not within Earth's atmosphere. It is the region where energy generated by nuclear fusion in the Sun's core is transferred through radiation. Therefore, it doesn't have a protective effect on Earth's atmosphere.
d. Convection currents: Convection currents mainly occur in fluids, such as in the Earth's atmosphere or in liquids like water. They are responsible for heat transfer through the movement of fluids caused by temperature differences. While convection currents can influence weather patterns and atmospheric circulation, they are not specifically responsible for protecting the atmosphere from solar wind.
Therefore, the correct answer is c. magnetosphere, as it functions as a shield against solar wind by deflecting and trapping charged particles and preventing them from directly impacting Earth's atmosphere.
