Answer:
True
Explanation:
The Cordilleras have one major factor that distinguishes them from the other mountain ranges, the three phases of its orogeny. Unlike most of the mountains in the world that have been created by a single orogenic process, that is not the case with the Cordilleras. There have been three consecutive orogenies, the Nevadan, Sevier, and Laramide orogenic process that created the Cordilleras, thus making them a unique mountain range.
During a volcanic eruption, the geosphere always interacts with the atmosphere, and that is the case with Mount Saint Helen's as well. During the eruption, the volcano which is part of the geosphere, releases lot of gases, ash, debris into the atmosphere. As they are propelled into the atmosphere, these volcanic products became part of the atmosphere, thus affecting its composition and properties, giving us a nice and simple example of interaction between the two spheres.
High levels of dissolved oxygen
It's true, Venezuela is the biggest supplier of oil to the U.S, also other countries like Saudi Arabia, Canada, Nigeria and Mexico.
