Answer:
formation process
Explanation:
farllon plate was fully subducted along pacific coast line
The cascade mountains formed from the igneous rocks by plate movement are younger and they are formed by the uplift of plates makes them appears aboveground in sierra Nevada.
What are cascade mountains in Sierra Nevada ?Since they were formed by melting above a subduction zone, the Cascades and Sierra Nevada's rocks are largely igneous. The Cascades, which initially arose 36 million years ago and are still forming now, are younger mountains.
In contrast, the Nevadan Orogeny, which occurred over 200 million years ago, is when the plutonic core of the Sierra Nevada started to form. When subducting at a sharp angle, oceanic lithosphere at the edge of the North American continent melted, and the magma surged back through the continental crust to form a volcanic arc.
The once-deep granite batholith that makes up today's Sierra Nevada was exposed by erosion after being raised by the North American plate. Although one small spur is located in Nevada, the elevated granitic intrusion is 640 kilometers long and largely located in California.

In a warehouse, the workers sometimes slide boxes along the floor to move them. Two boxes were sliding toward each other and crashed. The crash caused both boxes to change speed. Based on the information in the diagram, which statement is correct? In your answer, explain what the forces were like and why the boxes changed speed.Box 1 has more mass than Box 2. Box 1 and Box 2 are the same mass. Box 1 has less mass than Box 2
Answer:
There is no friction because of the mass.
Explanation:
The bigger box ran out of force to move so it hit the smaller box. (im in 7th grade and have the answer key)

Answer:
10.99s
Explanation:
Given parameters:
Speed of the fly = 9.1m/s
Distance flown = 100m
Unknown:
Time taken to fly this distance = ?
Solution:
Speed is distance divided by the time;
Mathematically;
Speed = [tex]\frac{distance}{time}[/tex]
Time = [tex]\frac{distance}{speed }[/tex]
Insert the parameters and solve;
Time = [tex]\frac{100}{9.1}[/tex] = 10.99s

Is it necessary to prepare sodium extract to detect nitrogen in urea ?
Answer:
I think No
Explanation:
An animal cell placed in a hypertonic solution will shrink in a process called crenation. An animal cell placed in a hypotonic solution will swell and potentially burst in a process called hemolysis. To prevent crenation or hemolysis, an animal cell must be placed in an isotonic solution such as 0.9% (m/v) NaCl or 5.0% (m/v) glucose. This does not mean that a cell has a 5.0% (m/v) glucose concentration; it just means that 5.0% (m/v) glucose will exert the same osmotic pressure as the solution inside the cell, which contains several different solutes. A red blood cell is placed into each of the following solutions. Indicate whether crenation, hemolysis, or neither will occur.
Solution A: 3.21% (m/v) NaCl
Solution B: 1.65% (m/v) glucose
Solution C: distilled H2O
Solution D: 6.97% (m/v) glucose
Solution E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl
Drag each solution to the appropriate bin.
Answer:
Solution A: 3.21% (m/v) NaCl ⇒ CRENATION
Solution B: 1.65% (m/v) glucose ⇒ HEMOLYSIS
Solution C: distilled H₂O ⇒ HEMOLYSIS
Solution D: 6.97% (m/v) glucose ⇒ CRENATION
Solution E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl ⇒ CRENATION
Explanation:
Isotonic solution = 0.9% (m/v) NaCl or 5.0% (m/v) glucose
Crenation will occur if the solution has a concentration higher than 0.9% (m/v) NaCl or 5.0% (m/v) glucose (hypertonic solution). This will occur in the following solutions:
Solution A: 3.21% (m/v) NaCl > 0.9% (m/v) NaCl
Solution D: 6.97% (m/v) glucose > 5.0% (m/v) glucose
Solution E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl (the addition of the 2 components exceeds the osmotic pressure permitted).
Hemolysis will occur if the solution has a concentration lower than 0.9% (m/v) NaCl or 5.0% (m/v) glucose (hypotonic solution). This is the case of:
Solution B: 1.65% (m/v) glucose < 5.0% (m/v) glucose
Solution C: distilled H₂O = 0% glucose/0% NaCl < 0.9% (m/v) NaCl or 5.0% (m/v) glucose
suppose that you are comparing several objects. is it correct to say that the object with the largest volume has the largest mass? explain your reasoning, and include an example. help!! asap!!
Answer:
No
Explanation:
It is not correct to say that an object with the largest volume has the largest mass.
Mass and volume are not directly related. In fact, the relationship between them can be direct or inverse.
Mass is the amount of matter in a substance. Volume is the space a body occupies.
A balloon and a stone for example is a typical one. A balloon has more volume but far lesser mass compared to a stone. A stone, gravel sized has low volume but more massive than a balloon.Therefore, it is wrong to say a balloon has more mass because it has more volume.

3) the north Pacific Ocean
Explanation:
Maritime polar air is defined officially as: Maritime polar (mP) air masses are cool, moist, and unstable. Some maritime polar air masses originate as continental polar air masses over Asia and move westward over the Pacific, collecting warmth and moisture from the ocean
Basically it's the North Pacific Ocean because of the higher latitude and colder air temperature

Plz answer
Answer: its B. The average kinetic energy of the particles.
Don’t trust the person above
Explanation:
I took the quiz and i got it right
A Temperature is a unit used to represent hotness or coolness on any of a number of scales, including Fahrenheit and Celsius. The direction that heat energy will spontaneously flow depends on temperature. The average kinetic energy of the particles is indicated by temperature. The correct option is B.
Temperature and heat are connected but distinct concepts. The average kinetic energy of a substance's particles is measured by its temperature. The kinetic energy of an object increases with its temperature. A sort of energy connected to motion is called kinetic energy.
The average kinetic energy of the particles in a substance is measured by temperature. The overall kinetic energy of the particles in a substance is measured by its thermal energy. The temperature and thermal energy of a substance increase with particle mobility.
Thus the correct option is B.

1. Salt has the chemical formula NaCl because it is made up of atoms of Sodium (Na) and Chlorine (CI).
Which statement most accurately describes this compound in relation to the elements it is made of?
A. When sodium and chlorine chemically combine they create a substance with completely different
properties
B. Salt has similar properties to the sodium and chlorine it is made of
C. Once salt is formed the sodium and chlorine atoms no longer exist, only salt atoms
D. Salt can easily be separated back into sodium and chlorine atoms through physical means
Answer:
A
Explanation:
When Na atom chemically combine with with Cl atom to form NaCl both atoms loose their chemical properties due to the fact that Na atom transfer an electron to cl atom. after transfer of electron Na atom become Na ion (cation) and Cl atom become Cl ion (anion)

other. Which statement is true about the particles that make up the bridge?
A When the sides of the joint are close together, the particles have more kinetic energy than they do when the sides are farther apart.
B. When the sides of the joint are far apart, the particles have more kinetic energy than they do when the sides are closer together
C. The particles contain the same amount of kinetic energy no matter how much the bridge has expanded.
