Answer:

Hello!

Question 1: <u>What is an earthquake?</u> Answer: An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.

Question 2: <u>What are faults?</u> Answer: In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements.

Question 3: <u>Why are earthquakes more likely to occur near faults?</u> Answer: Notice that many plate boundaries do not coincide with coastlines. Earthquakes can also occur far from the edges of plates, along faults. Faults are caused by all that bumping and sliding the plates do. They are more common near the edges of the plates.

Question 4: <u>What happens when the plates grind against each other? </u><u>Answer: </u>An earthquake is caused by the movement of Earth's crustal plates grinding against one another.

Question 5: <u>Is it true that when vibrations reach earth surface as earthquakes occur? </u>Answer: Yes! It's true that it vibrates near the earth surface!

Hope I helped! Ask me anything if you have questions! Brainiest plz. Hope You make a 100%! Have a nice day! -Amelia♥

A line and a point can be collinear” is correct about a line and a point.

 

In geometry a line:

• has no thickness, and 
• extends in both directions without end (infinitely). </span>

 

In modern mathematics, a point refers usually to an element of some set called a space. More specifically, in Euclidean geometry, a point<span> is a primitive notion upon which the geometry is built.</span>

A plane flies 450 miles with the wind, and 350 miles against the wind (in the same amount of time). If the wind is blowing at 30
adell [148]

Answer: = 240 mph.

Step-by-step explanation:

Let x = speed of the plane.

t= time taken

As per given, we have

t=\dfrac{450}{x+30}\ \ \ ...(i)\\\\ t=\dfrac{350}{x-30}\ \ \ ...(ii)    [Time = distance / speed]

From (i) and (ii), we get

\dfrac{450}{x+30}=\dfrac{350}{x-30}\\\\\Rightarrow\ 450(x-30)=350(x+30)\\\\\Rightarrow\ 450x-13500=350x+10500\\\\\Rightarrow\ 450x-350x=10500+13500\\\\\Rightarrow\ 100x=24000\\\\\Rightarrow\ x=240

Hence, the speed of the plane = 240 mph.
