<h3>What is the Earth system?</h3>
- The interactions between Earth's five systems—the geosphere, biosphere, cryosphere, hydrosphere, and atmosphere—create the conditions we are accustomed to.
- The rock cycle, the food chain, the carbon cycle, the nitrogen cycle, the water cycle, and the energy cycle are a few examples found in the Earth system.
- The major Earth circulation processes that move water, carbon, and nutrients renew essential elements for life and contribute to climate control. The continents, atmosphere, oceans, ice, and life on Earth are dynamic elements that constantly change and interact in a wide variety of ways.
- A system is made up of four independent spheres. A change in one sphere may result in another change because the spheres interact. Fields are plowed by humans (biosphere) using farm equipment made of geosphere materials, while plants are watered by precipitation (hydrosphere) brought by the atmosphere.

Answer:
change in frequency is 636 Hz
Explanation:
given data
speed v1 = 36 m/s
speed v2 = 45 m/s
frequency f = 500 Hz
speed of sound s = 343 m/s
to find out
what is the change in frequency
solution
we know here change of frequency formula that is
frequency = 
(f) ...................1
put here value in equation 1
and we take v2 = -45 because opposite direction
frequency = 
(f)
frequency = 
(500)
frequency = 636
so change in frequency is 636 Hz
Answer:
A separation technique to separate solids from a solution. Crystallization can be defined as the process through which the atoms/molecules of a substance arrange themselves in a well-defined three-dimensional lattice and consequently, minimize the overall energy of the system.
Explanation:
Answer:
5.68 m/s
Explanation:
The motion of the salmon is the same as a projectile: it is launched with an initial speed 
at an angle of 
above the horizontal.
The motion of the salmon consists of two indipendent motion:
- Along the horizontal direction, it is a uniform motion with constant velocity
So that the distance travelled is
(1)
- Along the vertical direction, it is a uniformly accelerated motion with constant acceleration downward, so the vertical displacement is
(2)
where g is the acceleration of gravity.
We know the following:
- The horizontal distance travelled by the salmon to reach the waterfall is
d = 2.33 m
- The vertical distance travelled is the height of the waterfall,
y = 0.488 m
From (1) we get:
And substituting into (2), we can solve the equation to find t, the time at which the salmon reaches the waterfall:
And then, we can use eq.(1) again to find the initial speed, u:
We will have that the graph that describes the scenario is given by graph B.
