If you joined Santa last Christmas at the north pole (90 degrees latitude), you would have seen Polaris straight overhead and the celestial equator on your horizon. The point straight overhead on the celestial sphere for any observer is called the zenith and is always 90 degrees from the horizon.
So the answer is the North Pole.
Higher density simply means new residential and commercial development at a density that is higher than what is typically found in the existing community.
Lower density describes housing developed at densities less than those recommended in the government's guidelines.
Cultures most typically develop without a conscious planning (but there are exceptions! So i would say that while B) and C) are not typically or commonly true, they could be true!).
They are usually simply a product of the interaction of people and their environment.
The most reliable way in which cultures are unique is when they''re not influenced by other cultures, so the best answer is A) The climate of the area may isolate the culture, preventing outside influences.
<span>The most volcanically active belt on Earth
is known as the Ring of Fire, a region of subduction zone
volcanism surrounding the Pacific Ocean. Subduction zone volcanism
occurs where two plates are converging on one another. One plate
containing oceanic lithosphere descends beneath the adjacent plate,
thus consuming the oceanic lithosphere into the earth's mantle.
This on-going process is called subduction. As the
descending plate bends downward at the surface, it creates a large
linear depression called an oceanic trench. These
trenches are the deepest topographic features on the earth's surface.
</span>
<span>The crustal portion of the subducting
slab contains a significant amount of surface water, as well as
water contained in hydrated minerals within the seafloor basalt.
As the subducting slab descends to greater and greater depths,
it progressively encounters greater temperatures and greater pressures
which cause the slab to release water into the mantle wedge overlying
the descending plate. Water has the effect of lowering the melting
temperature of the mantle, thus causing it to melt. The magma
produced by this mechanism varies from basalt to andesite in composition.
It rises upward to produce a linear belt of volcanoes parallel
to the oceanic trench, as exemplified in the above image of the
Aleutian Island chain. The chain of volcanoes is called an island
arc. If the oceanic lithosphere subducts beneath an adjacent
plate of continental lithosphere, then a similar belt of volcanoes
will be generated on continental crust. </span>

<span>The zone along the southern margins of the Sahara, which is experiencing desertification leading to drought, famine, and destitution, is called what?
</span><span>The zone along the southern margins of the Sahara, which is experiencing desertification leading to drought, famine, and destitution, is called Sahel. None of the option as you listed, don't go along the answer.
Thus, your answer is option C.
Hope I helped :D</span>
