Hi! I'm going to share a website quote that speaks about this, full disclaimer: the website is quoted and cited.
"Lines of latitude (parallels) run east-west around the globe and are used to measure distances NORTH and SOUTH of the equator. Since the equator is 0 , the latitude of the north pole, 1/4 of the way around the globe going in a northerly direction, would be 90 N. This is the highest latitude possible."

Planet Earth with its spherical shape has been divided by imaginary lines to establish geographical locations, climatic zones and time zones. These imaginary lines are the Meridians and Parallels. The meridians are imaginary lines that go from the north pole to the south pole and divide the earth by 360 ° in length; of which 180 ° in length are towards the west and 180 ° in length are towards the east taking as reference point 0 ° the Greenwich Meridian, dividing the earth in eastern and western hemisphere.
On the other hand, the parallels are imaginary lines that divide the earth horizontally taking as reference the line of the equator or 0 °, this pattern divides the earth in the northern hemisphere and the southern hemisphere each with 90 ° latitude. So, the correct answer is C. 180°W or 180°E.
Dune deflation hollows are where wind has removed sand down to a level where a layer of particles too heavy for the wind to move (an armoured surface) stabilises the sand and prevents the surface being lowered further.
A crevasse is a deep, wedge-shaped opening in a moving mass of ice called a glacier. Crevasses usually form in the top 50 meters (160 feet) of a glacier, where the ice is brittle.
a mass of rocks and sediment carried down and deposited by a glacier, typically as ridges at its edges or extremity.
"Natural" products are made from natural resources, like wood and sand. "Synthetic" products are also made from natural resources. For example, the synthetic material plastic is made from petroleum, which is pumped out of the earth
