The function of cilia is to remove foreign particles and mucus from the surface of the respiratory system. This is to prevent the blockage of airways.
terestrial
Sunspots are areas on the surface of the sun where strong magnetic fields keep charged particles trapped. Matter on the surface convects (gets heated, rises to the surface, cools, and sinks down only to be reheated and continue the cycle) but not the matter trapped in these magnetic fields. It can't sink back down once it cools off, which is why it looks black from Earth. These spots are still 3000 degrees kelvin (essentially Celsius) which is really hot but colder than the surrounding 5800 kelvin surface.

Generally, gas is trapped in a container, or under a curved surface.
some cells in this lining secrete a sticky liquid called mucus, which traps particles of dirt or bacteria that are breathed in. Other cells are covered with timy hair-like structures called cilia. It sweeps the mucus and trapped particles out toward the mouth.
No, it comes to the surface as lava from volcanoes.
Through water particles trapped inside
Ciliated Epithelial Cells have tiny hairs on them. These hairs sweep away any unwanted things, such as bacteria and dust which is trapped in mucus.
the clouds
Infectious agents, small aerosol and dust particles are trapped in the mucus elevator to prevent their invasion in lungs.
Particles in the air get trapped with condensed water vapor and carried to the surface of the earth with rain. From there, it can seep down to the watertable and polute rivers, streams, ponds, lakes, etc.

No. it is created by the Earth's magnetic field, and particles trapped in it from the Solar wind.
