The red line marks the fall line, the boundary between hard bedrock in the mountains and soft sediments in the coastal plains. stream gradient changes here, and it is marked by a series of waterfalls.
What does a fall line mean in Geography?An area where the upland region and a coastal plain merge are known as a fall line (or fall zone) and it is usually noticeable where rivers pass it, creating rapids or waterfalls.
This coastal plain is made up of softer sedimentary rock, while the uplands are composed of comparatively hard crystalline basement rock. As river clears away the uphill dense debris, a fall line will frequently move downstream, exposing bedrock shoals and, thereby creating "c"-shaped waterfalls.
A quick change in the elevation of the water and resulting energy release make the fall line a good location for water mills, grist mills, and sawmills. By seeking head of navigation with a ready supply of water power, the people have long made settlements where rivers cross a fall line.

Using the formula the depth in meters for the following echo soundings are given as follows:
5,250 meters2,250 meters6750 meters1,500 meters.How did we arrive at the following answers?The formula is already given as:
Ocean Depth = 1/2 ( 1500meters x echo travel time)
Hence, for a:
Ocean Depth = 1/2 (1500 x 7) = 5,250 meters
For b:
Ocean Depth = 1/2 (1500 x 3) = 2,250 meters
For c:
Ocean Depth = 1/2 (1500 x 9) = 6750 meters
For d:
Ocean Depth = 1/2 (1500 x 2) = 1,500meters
It is to be noted that
The average depth of the ocean is about 3,688 meters (12,100 feet). The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S.

A. Increased availability of food
B. Decreased resistance to parasites
C. Increased competition with carnivores
D. Decreased number of primary producers
Increased availability of food environmental factors would have most likely led to the change in the harbor seat population size from 1980-1990. The correct option is B.
How is food availability correlated with population growth?As the population grows, so does the demand for food, which usually necessitates the use of more arable land and water.
Plants are the primary source of food for people living in overcrowded countries because they cannot afford the 90% energy loss that occurs when plants are fed to animals. At the herbivore level, the same amount of grain can support ten times as many people as at the carnivore level.

New variety arises through mutations. Natural selection merely modifies the amount of variety already existing in the population; it does not produce new features. The development of new adaptive characteristics results from the recurrent two-step interplay of these processes.
What are Mutations?Generally, Any change in the DNA sequence of a cell. Mutations may be caused by mistakes during cell division, or they may be caused by exposure to DNA-damaging agents in the environment.
In conclusion, The origin of new variations may be traced back to mutations. Natural selection does not produce novel features; rather, it only modifies the amount of existing variation that is present in a population.

When pressure is applied to a pile of sediments, the grains will pack together more tightly, taking up less volume. water, however, simply stores the pressure this is because water is nearly incompressible.
What is water?Generally, Water is almost incapable of being compressed, particularly when kept under typical circumstances.
If you place a straw inside of a sandwich bag and then fill the bag with water, when you squeeze the bag, the water won't be compressed as it would if you only squeezed the bag. Instead, it will fly out of the straw.
If you apply pressure to a pile of sediments, the grains will pack together more tightly, resulting in a reduction in the volume that they occupy. Water, on the other hand, just stores the pressure; this is due to the fact that water is almost impossible to compress.

what might happen to a losing stream as the water passes from flowing over hard, impermeable rocks to flowing over more permeable rocks?
In a losing stream, if the water passes from flowing over hard and impermeable rocks to flowing over more permeable rocks, then, such steam will lose more water to the subsurface and might disappear.
What is the feature of losing stream?In geography, a losing stream is also called a disappearing stream, influent stream or sinking river, which is a stream that loses water as it flows downstream.
The water from this channel infiltrates into the ground recharging the local groundwater because the water table is below the bottom of the stream channel. They are more common in arid areas due to the climate which results in huge amounts of water evaporating from the river generally towards the mouth.
