• What factors do you
think will affect
water entering the
drainage basin
Basin size, Basin shape, Elevation and slope, Rock type, Soil type, Drainage density, and Rainfall type are the factors I think will affect water entering the drainage basin.
The majority of precipitation that accumulates in a stream's drainage basin and subsequently flows through the USGS monitoring station. The amount of streamflow that passes through the monitoring station depends on a number of variables, some of which are described above. Consider that a sizable (and durable) plastic sheet has been used to cover the whole basin. If it rained an inch, all of it would land on the plastic, flow off into gulleys and little streams, and then eventually drain into the mainstream.
Following the processes of condensation and cloud formation, precipitation enters the drainage basin as the first water cycle input. In addition to being captured by trees and other plants, this precipitation may be held on the surface as snow or ice (surface storage).

Considering a model of earth with no continents and with no rotation but heated like the real earth. The warm air around the equator and cold air at the poles. In such a model, the chances of possibility of survival are very low as this model doesn't support life on earth.
The rotation of the earth around its axis plays a significant role as its rotation is responsible for the occurrence of changing seasons and weather throughout the year around the globe.
Polar regions are colder than equatorial regions. If the earth stops rotating then the pattern of global winds would completely change.
The exchange of air in the atmosphere will be only in a back-and-forth motion.
Resultantly, the poles will be too cold to survive and the equator too hot to live in due to the hot and warm air around the equator. Unfortunately, this model doesn't support life on earth.
As the earth rotates, it moves warm air masses from the hot hemisphere to the cold hemisphere to maintain the temperature at a moderate level and vice versa. So, in order to maintain survival on earth, its rotation plays a crucial role.

where does a medial moraine develop? group of answer choices in the middle of two coalesced glaciers. on the side of a glacier. at the top of a glacier. near the bottom of a glacier.
The correct answer is option A.
A medial moraine develops in the middle of two coalesced glaciers.
In geology, the point where two tributaries of glaciers meet together is called a medial moraine also called a deposited rocky material.
In general, a medial moraine is a rocky and surficial pathway or feature that lies in the middle of two glacial tributaries or glacial convergence points. It is formed when a rock wall falls in the middle and gets deposited there or when a rocky mud flowing along the way with the ice flow reaches in the middle and settles down there.
In general, a medial moraine is a long, narrow zone of rock and soil debris that is formed when two lateral zones of moraines join at the intersection of two glacial streams.

A place such as central pennsylvania, home of penn state’s university park campus, is fairly typical of the world in terms of rainfall. What happens to the rain that falls on central pennsylvania each year?.
Rain that falls on central Pennsylvania each year most of it is evaporated.
Water is essential to life, and life is very skilled at using it. When trees have leaves, they absorb nearly all of the rain that falls during that time. Tree roots also penetrate deep into the earth and absorb part of the water from rain and snowmelt during the colder months.
Although the bulk of water still reaches the plants, a considerable percentage of it (perhaps 30% of the total) does sink into the earth and flow to streams. The amount of water that does flow across the surface is increasing as we plough the field, even if most of the land is not paved and little water flows across natural surfaces to streams.

How does the tundra contribute to a reduction of carbon dioxide on earth? how is climate change affecting the tundra’s ability to reduce carbon dioxide?
This causes organic matter to decompose faster, releasing larger amounts of carbon dioxide into the atmosphere.
Tundra soils are thawing more thoroughly and for a longer period of time in the higher layers of the surface as a result of climate change.
On Earth, the tundra is a biome that makes up around 20% of the planet's surface and is almost entirely found in the Northern Hemisphere. It is one of the largest natural CO2 sinks and a setting that aids in regulating the amount of CO2 in the atmosphere.
Because the tundra is freezing and the decomposition is very slow, most of the CO2 remains stored and doesn't enter the atmosphere while the living species in it use it for their needs. When they are no longer present, however, they remove some of it from the atmosphere.

What is a Line Segment?A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.
Point G is on EF which divides it such that EG: FG is 3:1
Let the coordinates of G would be (x, y)
The coordinates of the endpoints of EF are E(–16,–12) and F(–4,0) which are given in the question.
EG = (x+16, y+12)
FG = (x+4, y -4)
EF = (12, 12)

O Arithmetic density does not take birth rates into account.
The population of Egypt is unevenly distributed.
O Most Egyptian women over the age of 50 are illiterate.
O Cairo is one of the world's largest cities.
The arithmetic density for Egypt may not be the best way to determine how dense Egypt's population is because the population of Egypt is unevenly distributed.
Arithmetic population density can be misleading because it does not show the uneven distribution of population in a country. Arithmetic density lets us know and understand where urbanisation is occurring.
If we consider the large area of land, the arithmetic density becomes meaningless because it "blends in" the urban population and masks the sparsely- inhabited areas with an average.
The population density of Egypt as a whole is 84 people per square kilometre, with Cairo having the heaviest density at 46,349 per kilometre square. Egypt is the most populous Arab country with a population currently estimated at over 98 million.

The correct answer is option C: molten rock that cools and hardens on the Earth's surface.
Lava is molten rock that cools and hardens on the Earth's surface.
Lave is formed as a result of volcanic activity or volcanic eruption.
In the center of earth 'core, rocks and tectonic lithosphere melts under immense temperature and pressure forming hot molten magma which is made up of gases, molten rock and crystals.
When a volcano erupts, excessive pressure is released and molten magma comes out of it and flows down the sides of the volcano.
The chemical composition of lava indicates that it is composed of gaseous bubbles, volcanic glass and crystals.
In general, lava flows refer to extremely hot liquids but once they flow down the surface, heat dissipates in the surrounding, and they begin to cool down and ultimately transform into hard rocky surface on earth.
