Grade 5 Science Processes Quiz

What is cellular respiration?

• Cellular respiration is the process of breaking down water into oxygen and hydrogen

• Cellular respiration is the process of converting light energy into chemical energy

• Cellular respiration is the process by which cells break down glucose and other organic molecules to produce energy in the form of ATP.

• Cellular respiration is the process of producing glucose from carbon dioxide and water

What is light refraction?

• The reflection of light off a surface

• The emission of light from a source

• The absorption of light by a medium

• The bending of light as it passes from one medium to another.

Explain how light changes direction when it passes through different mediums.

• Refraction

• Reflection

• Scattering

• Absorption

What is frictional force?

• The force that helps the motion of an object when it is in contact with another object.

• The force that opposes the motion of an object when it is in contact with another object.

• The force that causes an object to float when it is in contact with another object.

• The force that has no effect on the motion of an object when it is in contact with another object.

How does friction affect the motion of an object?

• Friction makes the object move in a straight line.

• Friction has no effect on the motion of an object.

• Friction speeds up the motion of an object.

• Friction slows down the motion of an object.

What are the different types of friction?

• Smooth friction, rough friction, bumpy friction, and sharp friction

• Static friction, kinetic friction, rolling friction, and fluid friction

• Fast friction, slow friction, medium friction, and high friction

• Hard friction, soft friction, solid friction, and liquid friction

What is weathering and erosion?

• Weathering is the process of solidifying rocks, soil, and minerals through exposure to the atmosphere. Erosion is the process of dissolving weathered material from one location to another.

• Weathering is the process of creating rocks, soil, and minerals through exposure to the atmosphere. Erosion is the process of adding weathered material from one location to another.

• Weathering is the process of building up rocks, soil, and minerals through exposure to the atmosphere. Erosion is the process of removing weathered material from one location to another.

• Weathering is the process of breaking down rocks, soil, and minerals through exposure to the atmosphere. Erosion is the process of moving weathered material from one location to another.

Explain the difference between weathering and erosion.

• Weathering and erosion are the same process.

• Weathering breaks down rocks, while erosion transports the broken materials.

• Weathering only occurs in deserts, while erosion only occurs near water.

• Weathering creates new rocks, while erosion destroys rocks.

Name the different types of weathering.

• Mechanical weathering and chemical weathering

• Fast weathering and slow weathering

• Hot weathering and cold weathering

• Daytime weathering and nighttime weathering

What is water precipitation?

• Any form of water that falls from the atmosphere to the Earth's surface.

• Any form of water that is found in underground reservoirs.

• Any form of water that rises from the Earth's surface to the atmosphere.

• Any form of water that turns into solid ice on the Earth's surface.
