The mantle is heated in the core, where it is hotter it is more buoyant, whereas in areas where it is cooler it is less buoyant. This results inconvection cells in the mantle, and produces horizontal motion of mantle material close to the Earth surface.

Question
Which of the following describes groundwater? Groundwater is a renewable resource. Groundwater flows quickly. Groundwater exists only in regions that get a lot of rain. Groundwater does not exist during dry periods.
Solution 1

Answer:  Groundwater exists only in regions that get a lot of rain.

Groundwater is the reservoir of water this water accumulates in the ground surface or subsurface of the earth crust through tiny pores and fractures in the rocks. The source of water are streams of rivers, oceans, lakes and large depositing is because of water from the rain and melting of the snow. It is a source of freshwater in nature.

According to the above description, Groundwater exists only in regions that get a lot of rain can be considered as correct option.

Solution 2
I believe it is the 2nd one because the ground purifies it over a period of a little while.

Explanation:

Question
The motion of an object will not be changed if
Solution 1
Balanced forces acting on an object cause no change in the motion of the object.
Solution 2
As long as the motions are balanced there will be no changes

Question
Evaluate the important of radioactive isotopes in determining the age of earth
Solution 1

Radioisotopes are different species of the same chemical atom which varies in atomic masses but have the same atomic number. They have an unstable nucleus which results in the release of excess energy in the form of gamma, beta and alpha rays.

• Radio active elements are used in determining the age of the planet and other fossils discovered by radiometric dating.

• The radioactive elements have a special feature of breaking down over time with a constant rate of decay resulting in the geological evidence of ages which can be determined by the half-life of radioactive substances.

Therefore, radioactive isotopes are important in determining the age of the earth.

Solution 2
If we can measure the half life of the oldest materials we can determine based on radioactive decay how old the objects are... hope it helps
Question
Two people push on the same door from opposite sides as shown they will only see the door move when
Solution 1
One of them overpowers the other
Solution 2

Explanation: The only way that they will be able to see the door move is if only ONE of them exert more force than the other.

You can see that when they both exert the same force on the door, the forces are balanced, and cancel eachother out.

Hope this helped.

Have a nice day. :)

Question
How do we feel the energy of infrared waves? a. light b. heat c. vibrations
Solution 1
Infrared waves feel like heat since you can not really feel light.
Solution 2
B. "heat" hope that it helps :)
Question
How do we feel the energy of infrared waves?
Solution 1
When an object is not quite hot enough to radiate visible light, it will emit most of its energy in the infrared. For example, hot charcoal may not give off light but it does emit infrared radiation which we feel as heat. The warmer the object, the more infrared radiation it emits.

hope this helped :)

Solution 2
We feel infrared waves from the heat that they produce
