Continental rifting
If the diverging plates are capped by continental crust, fractures develop that are invaded by the ascending magma, prying the continents farther apart. Settling of the continental blocks creates a rift valley, such as the present-day East African Rift Valley.

How can you tell is energy has been transferred or transformed
Answer:
In mY Knowledge
Energy transfer is the movement of energy from one location to another. Energy transformation is when energy changes from one type to another. While energy can be transferred or transformed, the total energy always remains the same.
Hope iT HeLps :D
Answer:
You can tell if energy has been transferred when something works when you put a body of energy in it. For example, you'll know when energy is transferred if you plug a lamp cord into an electric socket and the lamp turns on. Energy is being transferred from the socket to the lamp.
You can tell when energy is being transformed when it changes from one energy to another. You can know when energy is being transformed when you turn on a stove. Chemical energy transforms into electric energy.
I hope that helps!

How do latitude and proximity to bodies of water relate to the temperature?
Answer:
The answer is below.
Explanation:
According to geographical coordinates and related information, when the latitude is lower, that is closer to the equator the temperature becomes warmer. While the far away from the equator the latitude is the temperature decreases.
Similarly, the water bodies have a relative effect that is considered little or less severe on the temperature throughout any of the seasonal period or day and night.
Why can we say that the ratio of net force to mass is constant forany dropped object on Earth?
Answer:
All objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity.
Explanation:
Newton's Second Law, if I remember right.
According to the rock cycle, when liquid magma cools into a solid, what is formed?
Answer:
Similarly, liquid magma also turns into a solid — a rock — when it is cooled. Any rock that forms from the cooling of magma is an igneous rock. Magma that cools quickly forms one kind of igneous rock, and magma that cools slowly forms another kind. ... The kind of rock formed in this way is called intrusive igneous rock.
Explanation:
Answer: Igneous rock.

A woman does 236 J of work
dragging her trash can 24.4 m to
the curb, using a force of 18.9 N.
At what angle was her force
directed?
(Unit = degrees)
Answer:
The woman's force was directed 59.22⁰ to the horizontal.
Explanation:
Given;
work done by the woman, W = 236 J
distance through the load was moved, d = 24.4 m
applied force, F = 18.9 N
inclination of the force, = θ
The work done by the woman is calculated as;
W = Fdcosθ
[tex]cos \ \theta = \frac{W}{Fd} \\\\cos \ \theta = \frac{236 }{18.9 \times 24.4} \\\\cos \ \theta = 0.5118\\\\\theta = cos^{-1} ( 0.5118)\\\\\theta =59.22^0[/tex]
Therefore, the woman's force was directed 59.22⁰ to the horizontal.
Answer:
59.22⁰

49. A 6.1-kg bowling ball is liſted 2.1 m to a shell. Find
the increase in the ball-Farth system's energy.
Answer:
125.5J
Explanation:
Given parameters:
Mass of the bowling ball = 6.1kg
Height of lifting = 2.1m
Unknown:
Increase in the ball energy = ?
Solution:
The ball has changed position by moving it from one point to another. So, it has acquired more potential energy.
Potential energy = mgh
m is the mass
g is the gravity
h is the height
Now insert the given parameters and solve;
Potential energy = 6.1 x 9.8 x 2.1 = 125.5J
A captain of a fishing boat notices that during a certain time each year high tides are higher and low tides are lower. Which conclusion could the captain accurately draw?
Answer:
The Moon is at the closest part of its orbit around Earth; the Sun and the Moon form a straight line with Earth.
Explanation:
The conclusion the captain could draw accurately is that;
The moon is probably at the closest part of its orbit moving round the earth. In addition, that the sun and the moon have formed a straight line with earth. This is due to the fact that high tides are higher and low tides are lower at a particular time each year.
Suppose a woman raises a 65 N object in 2m in 4 seconds.
Calculate the work is done and her power.
Science
Answer:
[tex]\huge\boxed{\sf P.E = 130\ Joules}[/tex]
[tex]\huge\boxed{\sf P = 32.5\ Watts}[/tex]
Explanation:
Given Data:
Weight = W = 65 N
Height = h = 2 m
Time = t = 4 secs
Required:
Power = P = ?
Work Done in the form of Potential Energy = P.E. = ?
Formula:
P.E. = Wh
P = P.E. / t
Solution:
P.E. = (65)(2)
P.E = 130 Joules
P = P.E. / t
P = 130 / 4
P = 32.5 Watts

~AH1807You and your friends are playing tug of war. Your team pulls with a force of 55 N, to the right. The other team pulls with a force of 65 N to the left. What is the net force on the rope
Answer:10 N
Explanation:
Subtract them and u will see it will be 10n so the net force will be 10 n why you should subtract them is because
They both are different amounts
Different forced of strength
Different N numbers
Think of it like the is an unequal amount of student so one side has 2 students and the other side has 4 students
Thanks for the help :)

A ball rolls across the ground and slows to a stop.
Does gravity do work in stopping the ball?
Explain.
(Drawing a picture will help.)
gravity does help the ball since gravity pulls down objects, it causes more friction on the ball therefore causing the ball to slow down faster.
Compare the speed that light waves travel in air to the speed that sound waves travel in the air. How many times faster do light waves travel in air in comparison to sound waves in air?
Answer:
As a rule sound travels slowest through gases, faster through liquids, and fastest through solids. The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour. ... Speed of light in glass = 200 million m/s or 182,300 mph.
Explanation:
Almost always sound travels slowest via gases, faster via beverages, and fastest via solids. The velocity of light because it travels via air and area is a great deal quicker than that of sound; it travels at 300 million meters consistent with 2d or 273,400 miles in step with hour.
The pace of light in glass = 2 hundred million m/s or 182, 300 mph.
How are light waves and sound waves extraordinary?Mild waves are electromagnetic waves whilst sound waves are mechanical waves. Mild waves are transverse even as sound waves are longitudinal. Light waves can tour in a vacuum. Sound waves require a material medium to journey, and as a result, can not travel in a vacuum.
Nothing can travel faster than light except for sound. This is the declaration of a few US physicists, who say they've designed an unusual waveguide to make the sound move at “superluminal” speeds (Appl. Phys.
In 2015, a team of Scottish scientists announced that they had found a way to gradual the rate of mild. By sending photons via a unique mask, the researchers altered their shape. In this malformed kingdom, these infinitesimal particles of light traveled slower than normal photons.

how do mass and distance affect the force of gravity between on objects
The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.

1. How does speed affect the amount of kinetic energy in a moving object? Explain how you
know by stating your claim, the evidence for your claim, and your reason why this evidence
supports your claim.
I’ll mark as brainliest
Explanation:
The kinetic energy of a moving object is directly proportional to its mass and directly proportional to the square of its velocity. This means that an object with twice the mass and equal speed will have twice the kinetic energy while an object with equal mass and twice the speed will have quadruple the kinetic energy.

A badminton shuttlecock leaves the racquet traveling 30 m/s. It goes over the net 0.5
seconds later with a speed of 10 m/s. Calculate its average acceleration.
Answer:
[tex]a=40\ m/s^2[/tex]
Explanation:
Given that,
Initial speed of a shuttlecock, u = 30 m/s
Final speed of the shuttlecock, v = 10 m/s
Time, t = 0.5 s
We need to find its average acceleration. The acceleration of an object is equal to the change in speed divided by time taken. It is given by :
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{10-30}{0.5}\\\\a=-40\ m/s^2[/tex]
So, the average acceleration of badminton shuttlecock is [tex]40\ m/s^2[/tex].
