We have all noticed that if we hike from a place with low elevation and go up at a place with high elevation, that the temperature is gradually dropping, thus giving us a clue that the lower places are warmer, while the higher places are cooler. The reason for this, even though both the places with low and high elevation are located in the troposphere, thus the same atmospheric layer, is that the density of it is not the same everywhere. The troposphere has the highest density at its lowest points, and as the height increase the density decreases. Since the higher parts are less dense, that means that there are less gases, thus there are less molecules that are further apart from each other. This results in lesser absorption of heat, so this parts are cooler, while the lower parts are warmer because the troposphere is denser, there's more molecules that are also closer to each other, thus they absorb more heat.
Answer:
runoff, rill, gully, stream, tributary, and river.
Explanation:
Answer:
Agriculture allowed people to stay in one place, and increased food production caused the population density to expand far beyond levels that could be sustained by hunting and gathering alone. This growth in population density provided a critical mass of people to sustain and spread contagious infectious diseases.
The main difference between geography and geology
is that geography is mostly dealing with the physical overall shapes of
the land. Geology is a science that is interested in how the land got
into the shape it did.
Geology is mostly about what the ground is
made up of from a natural perspective. What kind of rocks it contains
and how those rocks or layers of rocks got there.
Geography is
mostly dealing with mapping the extent of landforms, how far rivers are,
how long mountain ranges are, how long the coast line is. This is often
from the perspective of people or culture.
