The surfaces of the inner, terrestrial planets of our solar system are composed of volcanoes, craters, canyons, and mountains.
The interstitial planets are made up of rocks, silicates, minerals, carbon or in case of earth water as well. Generally the planets have an inner core made up of iron which is further surrounded by a mantle.
Our earth is the only planet in the universe which is found to have water at its surface while the planet Mars also has polar ice caps which are permanent just like our earth. The inner terrestrial planets consist of mercury, Venus, earth, and Mars.

Answer:
Option A, Mobile source
Explanation:
A mobile source of pollution pollutes the environment while moving. It does not stay at one constant position like a chimney of industry or a stationary machine releasing pollutant gases. Hence, all the moving vehicles, automobiles, diesel engines etc. which release harmful things thereby degrading environment are called mobile source of pollution. Thus, a car releasing pollution while driving through the Grand Canyon will be considered as mobile source of pollution.
