Do you
think a colony on Mars should be nearer the northern or southern
polar cap? Explain.

Hola TvT

Explanation:When the Martian polar caps were first viewed through telescopes, most scientists believed that they were made of water ice, like the polar caps on Earth. Like Earth, Mars has a North and South Pole. But while Earth's polar ice caps consist solely of water ice, Mars' polar caps are a combination of water ice and carbon dioxide ice. As the Martian seasons change, the carbon dioxide ice sublimates (vaporizes) in summer, revealing the surface, and freezes again in winter. As fall approaches, in each respective hemisphere, clouds begin to form over the polar region and the ice cap begins to grow. In spring, the polar caps recedeAside from ice, Mars' polar regions have some interesting geologic features. The north polar dune field is a vast concentration of sand dunes that stretches around the entire north polar cap. In some areas, the sand measures up to 500 km (300 miles) across. When the dunes begin to thaw in spring, dark spots form on their surfaces. The north polar dunes were first seen during the 1972 mapping of Mars by Mariner 9, and they are identical to dunes in Earth's desert regions..

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
