The Andes Mountain range is the longest and one of the highest mountain ranges in the world. Believed to have been created 50 million years ago, this mountain range is a collection of numerous mountain chains that are joined and line the western edge of South America. From Venezuela down through Chile to the southern tip of the continent, it spans over seven countries. This mountain chain is part of a subduction zone home to many of Earth’s active volcanoes. How were the Andes mountains created? The movement of the continental crust sliding under the lighter oceanic crust created the mountain chain. The movement of the Earth where the tectonic plates slowly diverge from each other created the mountain chain. The movement of tectonic plates converging that cause the dense oceanic crust to slide under the continental crust created the mountain chain. The movement of convection currents that cause tectonic plates to diverge allowing one to slide under the other created the mountain chain.

Nanotechnology, the field of trying to build ultrasmall structures one atom at a time, has progressed in recent years. one potential application of nanotechnology is the construction of artificial cells. the simplest cells would probably mimic red blood cells, the body's oxygen transporters. for example, nanocontainers, perhaps constructed of carbon, could be pumped full of oxygen and injected into a person's bloodstream. if the person needed additional oxygen-due to a heart attack perhaps, or for the purpose of space travel-these containers could slowly release oxygen into the blood, allowing tissues that would otherwise die to remain alive. suppose that the nanocontainers were cubic and had an edge length of 24 nanometers. part a part complete what is the volume of one nanocontainer? (ignore the thickness of the nanocontainer's wall.) express your answer using two significant figures. v v = 1.4ă—10â’20 l previous answers correct significant figures feedback: your answer 1.3824â‹…10â’20 = 1.382ă—10â’20 l was either rounded differently or used a different number of significant figures than required for this part. if you need this result for any later calculation in this item, keep all the digits and round as the final step before submitting your answer. part b suppose that each nanocontainer could contain pure oxygen pressurized to a density of 81 g/l . how many grams of oxygen could be contained by each nanocontainer?

The atoms of a solid aluminum can are close together, vibrating in a rigid structure. if the can is warmed up on a hot plate, what happens to the atoms?
