Tall , conical volcano that is made of a layer of hardened lava, ash and tephra is referred as stratovolcanoes.
Explanation:
A stratovolcano requires more than thousands year time to form. Various type of magma type are erupted from this volcano they are rhyolite, basalt,dacite and andesite. When eruption occurs huge amount of gases are evolved. In case of stratovolcanoes periodic explosion takes place.
The lava that comes out is highly viscous and the lava cools very fast and hardens before going too far. Mt. St. Helens is one of the example of stratovolcano.
The environment of a place is mobile and dynamic in character it can impact both the local and global climates of any place on earth. The <u>atmospheric circulation, oceanic currents, and biogeography</u> of a place have an impact on the local climate and weather pattern of the place.
Like places in poles are cool and have cold environments that affect the general circulation of the atmosphere of the planet by the current produced in oceans and air as a polar cell.
Similarly palace on the equator is in direct contact with the sunlight and thus their environment is of calm nature hence, the convective currents develop over here.
Thus the environment is what surrounds us can directly and indirectly impact the local which will lead to a change in global changes as well.
