Answer:
Option A) Fall Line
Explanation:
A fall line is a geological boundary that is formed between an upland region and a plain beneath. Usually, the regions are identified by falls or rapids when rivers and streams cross or meet.
One interesting feature is that the fall lines are formed when rivers meander through regions of weak rock structure. Normally, the rock structure is sedimentary rock structure (layered). The rivers tear into the earth by erosion, abrasion and attrition.
In addition, plate tectonics play an important role. The movement of the earth's plates causes the falls. Some are formed by the rapid freeze-thawing action of large blocks of ice.

Explanation:
Answer: Doppler effect
Explanation:
The Doppler effect refers to the change in a wave perceived frequency when the emitter of the waves, and the receiver (or observer in the case of light) move relative to each other.
In other words, it is the variation of the frequency of a wave due to the relative movement of the source of the wave with respect to its receiver.
Another important aspect is that the effect occurs in all waves (including light and sound). However, it is more noticeable to humans with sound waves.
The Doppler effect is the apparent change in frequency of waves due to the motion of a source.
The gravitational field intensity (EG) or (g) is the force on a unit mass at a point in the field.
Since the force (F) on a body of mass m in a gravitational field of a body of mass M = GMm/r2 .
you can see that the force per unit mass is given by F/m. So:
Gravitational Field Intensity (EG) = (g) = F/m = GM/r2
The units for EG are N kg -1 or since F = ma, F/m = a and so EG may be expressed in ms -2
Hope this will help you :))
Do give this answer a brainliest :D
Question 1 options:
gas, solid, liquid
gas, liquid, solid
solid, liquid, gas
solid, gas, liquid
The state of matter with an indefinite shape and definite volume is _____.
Question 3 options:
Solid
liquid
gas
plasma
plasma
Deposition and condensation is an example of an endothermic reaction
Question 7 options:
True
False
Which one of the following statements best describes the particles in a gas?
Question 8 options:
They are very close together and are able to vibrate.
They are stationary and not able to vibrate
They are moving very slow and are far apart.
They are moving very fast and are far apart.
Question 1'sanswer is gas, liquid, and solid.
Why? Think about it - solids hold better than any of those two - And gasses hold the weakest and liquid goes in the middle :)
Question 3 is liquid, because if you put like, we'll say water, if you put water into a round bottle it would look round, right? It would go for any other shaped bottle - It would look like that same shape. But you can't change the volume - It will always be the same
Question 7 is FALSE - They're actually exothermic reactions. :)
Last question 8 - They are moving very fast and are far apart -
Note that the closer together molecules are together, the harder something is :D

Answer:
B) rain
Explanation:
The barometer is a device that is used to measure atmospheric pressure and, consequently, the height at which someone rises, as well as to approximately predict atmospheric changes. Thus, a rising barometer indicates an increase in air pressure, whereas a falling barometer indicates a decrease in air pressure.
In environments with low atmospheric pressure and, therefore, heat, the heated air tends to rise and, when reaching higher altitudes, condenses, forms clouds and precipitates. In this situation, the barometric pressure drops very, very quickly, indicating that a rain is coming.
Answer:
B
Explanation:
You would have rain. You would have clouds, precipitation, and strong winds.
The water balloon must accelerate m/s2.
Answer:
3.1 m/s²
Explanation:
Given:
Mass of the balloon (m) = 11.4 g = 0.0114 kg ( 1 kg = 1000 g)
Force acting on the balloon (F) = 0.035 N
Acceleration with which the balloon must be hit (a) = ?
Now, we know that, from Newton's second law, net force acting on an object is equal to the product of its mass and acceleration.
Therefore, framing in equation form, we have:
Rewriting in terms of acceleration 'a', we get:
Now, substitute the given values and solve for 'a'. This gives,
Therefore, the acceleration of the water balloon to reach the target must be equal to 3.1 m/s².
Answer:
3.1

Answer: The given statement is True.
Clouds are formed due to condensation of water vapors. Condensation can be described as a process of change of gaseous form of water (that is water vapor) into liquid form.
When sunlight strikes various aquatic bodies, water is heated up and it rises high in the atmosphere in the form of water vapors.
When these vapors meet a lower temperature in the atmosphere, they cool and the air loses its capacity to hold them.
Due to this, vapors condense and form clouds.
Thus, given statement is True.
