On a hot summer day, air rises most quickly when it is above a

forest

Answers

It would be Lake because the water bacteria is evaporating into clouds

On a hot summer day, air rises most quickly when it is above a desert. The correct option is C.

What is a desert?

A desert is a barren area of land with little precipitation and, as a result, hostile living conditions for plant and animal life.

The lack of vegetation exposes the ground's unprotected surface to denudation. Arid or semi-arid regions cover roughly one-third of the Earth's land surface.

Although the majority of deserts, such as the Sahara in North Africa and the deserts of the southwestern United States, Mexico, and Australia, occur at low latitudes.

Arid climates have less cloud cover than humid climates, and cloud tops reflect a significant amount of the sun's energy back into space, reducing surface heating. On a hot summer day, air rises the fastest above a desert.

Thus, the correct option is C.

Answer:

c

Explanation:

the wires are made of too many conductors

C.

If a power line were broken then power would not reach the light. Which is possible.

If a wire to the light or to the box in your house was broken your light would not receive power, therefore not turn on. Again possible.

If the power plant does not produce enough electricity, although unlikely, that would cause you to not be able to turn on your light. Unlikely but it would be true is it happened.


Finally C is not likely, your wires in your house are most likely made of copper but too many conductors in the wire, not only wouldn’t happen, but would most likely not interrupt your light working.

The question asks what is NOT a possible cause. C is the only not possible.

Answer:

You havent attached the choices so we cant tell u the answer

Answer:

I do not see the options but this is what I know.

Explanation:

At the boiling temperature, adding heat energy converts the liquid into a gas WITHOUT RAISING THE TEMPERATURE. In this case, the energy added to the liquid goes into breaking the bonds between the liquid molecules without causing the temperature to change. The same thing happens when a solid changes into liquid.

Which process begins the formation of sedimentary rock?

the movement of sediment
the cementation of rock sediment
the breakdown of rock into sediment
the buildup of sediment in one location

Answers

Answer:

Weathering breaks down pre-existing rock into particles, while erosion moves the particles to a site of deposition. These processes begin the formation of sedimentary rock.

Explanation:

Sediment is the term for the component that aids in the formation of sedimentary rock. All of the processes that lead to the sedimentation of organic and mineral particles are together referred to as sedimentation. The cementation of rock sediment forms sedimentary rock. The correct option is B.

What are sedimentary rock?

Sedimentary rocks are created by the material being deposited at the Earth's surface and then being cemented there by bodies of water. Existing rocks or pieces of extinct animals that have accumulated on the surface of the Earth over time generate sedimentary rocks.

Sediment is crushed and cemented as a result of deep sediment burial, creating sedimentary rock. The three types of sedimentary rocks are categorized as Organic, Clastic, and Chemical Sedimentary Rocks. Lime stone, clay, sandstone, etc. are some Sedimentary rocks.

The sediment particle size and fluctuation is the best indicator of the type of rock.

Thus the correct option is B.
