Explain the difference between a Long Profile and a Cross Profile of a River.

Geography

Answer:

The average flow velocity of a river increases along its long profile. This makes sense; along the profile, more potential energy is converted to kinetic energy, increasing the velocity. This is only the average velocity however; a cross-section of a river shows that the velocity varies from one side to the other.

Explanation:

a. There are gain to reproduce, if increase the number of seals, it's will increase the number of whales, because they eats the seals and become strongest to reproduce. If the seal’s birth rate goes up, the whales will benefit more. If the whale’s death rate increases, the seal’s will benefit more than the whales.

b. The more the whales capture, the fewer seals there will be. Over time, this will negatively affect both the seals and the whales.

How is the composition of rock on the seafloor different than rock on the land?
kvv77 [185]

Oceanic crust is dominated by mafic and ultramafic intrusive igneous rocks whereas continental rocks are dominated by granitic (felsic) intrusive igneous rocks.

The difference in density has an impact on isostacy of crust floating on the semi-fluid upper mantle (asthenosphere), with continental crust (about 2.7g/cm3) rising or floating above oceanic crust (about 3.5 g/cm3).  

The continental crust is by far the older of the two types of crust.

The mantle, oceanic crust, and continental crust all have different compositions due to a process called partial melting.

Because continental crust is less dense than oceanic crust it floats higher on the mantle, just like a piece of Styrofoam floats higher on water than a piece of wood does.

8. At what water depth will the wave described in Question 7 begin to break? 9. What two factors determine how far from the shor
zepelin [54]

Answer:

After reaching 1.3 times the height of the wave, the wave will break.

Explanation:

The wave will break when it reaches a water depth of 1.3 times the height of the wave. The two factors are depth of the seafloor and height of the wave determine how far from the shoreline waves will begin to break. when the depth of the seafloor decreases so the waves touches the ground and the wave is starting to break. The wave will start to break when the ratio between the height of the wave and wavelength of the wave is 1 : 7.
