What layer of atmosphere has lowest air pressure?; Which is the lower lowest layer of the atmosphere?
The troposphere is the correct answer. The layer is the lowest layer of our atmosphere. The layer has rock bottom pressure due to pressure drops as altitude increases. This is often because of the
Atmospheric air is forced towards the surface of the world because of gravity. This suggests air density is smaller as you go up because there's a lesser and lesser atmospheric state on top of you.

Three distinct geologic occurrences, in that order: the deposition of the first, lower rock layer, uplift, titling, erosion of the first rock layer, and deposition of the second, upper rock layer.
How does an angular unconformity develop?When original, horizontal strata are distorted, exposed at the surface, worn away, and then covered by newly deposited layers, angular unconformities result.
What has to occur to a rock layer in order to create an angular unconformity?An unconformity between two sets of strata that are not parallel to one another is referred to as an angular unconformity. It develops when fresh horizontal strata cover older ones that have been folded into mountains and eroded to a nearly level surface.

The quartz, feldspar, and mica fragments that make up granitic mountain sand are frequently angular in shape. Large sand hills known as dunes are created when powerful winds gather the tiny grains of desert lake bottoms and river deltas. Some sand dunes develop smooth, rounded grains that resemble small stones in a rushing stream after many millennia of rubbing against one another.

Which best describe shield volcanoes?
Typically, basaltic and/or andesitic lava flows that were quite fluid when they erupted make up practically the whole structure of shield volcanoes.
They were created by a series of eruptions that happened sporadically over a very long time (up to a million years or longer). Volcanoes with shields have significantly wider than taller surfaces. Shield volcanoes are so named because of their low profile, which resembles a warrior's shield resting on the ground.
It is created by the eruption of lava with a low viscosity (high fluidity), which travels farther and generates thinner flows than lava from a stratovolcano, which has a higher viscosity.
The shield volcano's unusual shape is formed as a result of several eruptions that gradually build up vast sheets of lava. Wherever flowing low-silica lava reaches the surface, shield volcanoes are found.

Which of these characteristics of a drainage basin would tend to promote a longer lag time between a rainfall event and peak discharge? (choose all that apply) larger drainage basin impermeable surfaces steep terrain more vegetation thick soils
Large drainage basins have a higher peak discharge than smaller basins because they can hold more precipitation. Because precipitation does not have as far to go, smaller basins typically have shorter lag times.
Runoff and outflow are also impacted by the drainage basin's form. Because water must travel a shorter distance to reach a river, drainage basins with a more circular shape have shorter lag periods and a higher peak discharge than those with a long, thin shape. Shallower drainage basins typically have longer lag times than those with steep slopes. This is due to the fact that water moves more swiftly down steep slopes toward rivers. High drainage density basins have a shorter lag time because they drain more quickly.
