A. Cirrus Clouds
- B.
B. Cumulus Clouds
- C.
C. Stratus Clouds
- D.
D. Nimbus Clouds
Correct Answer
B. B. Cumulus CloudsExplanation
Cumulus clouds are puffy clouds that sometimes look like pieces of floating cotton. The base of each cloud is often flat and may be only 1000 meters (3300 feet) above the ground.Rate this question:

When ice melts, it's mass...
- A.
A. decreases
- B.
B. increases
- C.
C. will change but go back to the original amount.
- D.
D. stays the same.
Correct Answer
A. A. decreasesExplanation
When ice melts, its mass decreases because the solid ice is converted into liquid water. Although the number of molecules remains the same, the arrangement of molecules changes from a solid to a liquid state, resulting in a decrease in mass.Rate this question:

What do you call the transfer of heat from molecule to molecule?
- A.
A. Convection
- B.
B. Conduction
- C.
C. Combustion
- D.
D. Condensation
Correct Answer
A. A. ConvectionExplanation
Convection happens when a substance that can flow, like water or air is heated in the presence of gravity. When air or water is in the presence of gravity, the gravity pulls all of it down. The bottom of the air or water becomes denser because it is pulled down and also pushed down by the weight of the molecules on top of it.When there is heat at the bottom of this air or water, the air or water molecules in contact with the heat start to move, and the molecules spread apart.Rate this question:

You need to separate the salt from the water in a salt solution. Which process will you use?
- A.
A.Filtration
- B.
B. Decantation
- C.
C. Separation
- D.
D. Evaporation
Correct Answer
B. B. DecantationExplanation
Decantation is a process for the separation of mixtures, by removing a layer of liquid, generally one from which a precipitate has settled.Rate this question:

It is a scientific study that focuses on birds.
- A.
A. Herpetology
- B.
B. Ichthyology
- C.
C. Ornithology
- D.
D. Entomology
Correct Answer
C. C. OrnithologyExplanation
Ornithology is a branch of zoology that concerns the study of birds. The word "ornithology" derives from the ancient Greek ornis ("bird") and logos ("rationale" or "explanation").Rate this question:

Which of the following allows water to move from Earth’s surface back into the air?
- A.
A. Gravity
- B.
B. Weathering
- C.
C. Condensation
- D.
D. Evaporation
Correct Answer
D. D. EvaporationExplanation
Evaporation is the process by which water changes from a liquid state to a gaseous state. It occurs when heat energy is applied to water, causing the water molecules to gain enough energy to break their bonds and become vapor. This allows water to move from Earth's surface back into the air. Gravity is responsible for pulling water downwards, not upwards into the air. Weathering is the breakdown of rocks and does not involve the movement of water into the air. Condensation is the process by which water vapor turns into liquid water, not the movement of water from the surface back into the air.Rate this question:

The protection of soil is called
- A.
A. Soil Erosion
- B.
B. Humus
- C.
C. Soil conservation
- D.
D. Gravel
Correct Answer
C. C. Soil conservationExplanation
Soil conservation is a combination of all methods of management and land use that safeguard the soil against depletion or deterioration by natural or human-induced factors.Rate this question:

A quick back and forth motion is called:
- A.
A. Pitch
- B.
B. Vibration
- C.
C. Wavelength
- D.
D. Amplituted
Correct Answer
B. B. VibrationExplanation
A quick back and forth motion is commonly referred to as vibration. Vibration typically involves the rapid oscillation or movement of an object or a part of an object. This motion can occur in various forms, such as mechanical vibrations, sound vibrations, or even electromagnetic vibrations. Therefore, out of the given options, "vibration" is the most appropriate term to describe a quick back and forth motion.Rate this question:

What do you call the materials that allow heat to pass through?
- A.
A. Transformation
- B.
B. Conductors
- C.
C. Conveyors
- D.
D. Insulators
Correct Answer
B. B. ConductorsExplanation
Conductor is an object or type of material that allows the flow of an electrical current in one or more directions. Materials made of metal are common electrical conductors.Rate this question:

Which is a good insulator?
- A.
A. Iron
- B.
B. Steel
- C.
C. Cloth
- D.
D. Copper
Correct Answer
C. C. ClothExplanation
The materials which do not allow heat to pass through are poor conductors such as plastic and wood. Poor conductors are known as "Insulators"Rate this question:

Which is true about heat?
- A.
A. Heat travels in a straight line.
- B.
B. Heat travels fastest in wood
- C.
C. Heat travels on any material
- D.
D. Heat travels in different ways
Correct Answer
D. D. Heat travels in different waysExplanation
Heat moves in three different ways: Radiation, conduction, and convection.Rate this question:

Which refers to the process where the heat of one substance is transferred to another?
- A.
A. Conduction
- B.
B. Convection
- C.
C. Condensation
- D.
D. Radiation
Correct Answer
A. A. ConductionExplanation
Conduction is another way that heat moves. Heat is a form of energy, and when it comes into contact with matter (Anything that you can touch physically) it makes the atoms and molecules move. Once atoms or molecules are moving, they collide with other atoms or molecules, making them move too. In this way, the heat is transferred through matter.Rate this question:
