Public Quiz: Unit 4 : Concept 4.1 Breaking Down and Moving Rocks (Science) - Primary 4 - Science

Question 1

What term describes loose, unconsolidated particles of rock, mineral, or organic material?

Igneous rock

Sediments

Metamorphic rock

Magma

Question 2

The formation of large geological features like canyons typically requires what kind of time frame?

A couple of months

Several days

A few minutes

Hundreds to millions of years

Question 3

What is erosion?

The process of rocks piling up in one place.

The process where sand, soil, or rocks are moved from one place to another.

The process that breaks rocks into smaller pieces.

The chemical alteration of rock composition.

Question 4

Hurricanes are a type of event where erosion can be observed.

True

False

Question 5

How does wind primarily cause mechanical weathering?

It carries sand and other particles that abrade rock surfaces.

It generates heat that melts rock structures over time.

It pulls large rock fragments directly from mountain sides.

It causes chemical reactions within rocks due to atmospheric pressure.

Question 6

What landform is created when a river deposits sediment as it enters a larger body of water?

A river delta

A canyon

A plateau

A mountain

Question 7

Which common material is used in the activity to represent the natural process of mechanical weathering?

Crackers

Water

Antacid tablets

Transparent plastic cups

Question 8

The disappearing sandcastles illustrate the power of which natural force?

Chemical weathering

Wind deposition

Water erosion

Volcanic activity

Question 9

Which natural process is responsible for transporting rock pieces and other materials through the movement of water?

Biological weathering

Water erosion

Glacial erosion

Wind erosion

Question 10

How far can wind typically move grains of sand blown by a gentle wind?

Thousands of meters

A meter or so

Only a few centimeters

Hundreds of kilometers

Question 11

What happens to soil on hilly farmland due to rain?

Rain pushes the soil uphill.

Rain washes the soil downhill little by little.

Rain causes the soil to become more fertile.

Rain compacts the soil in place.

Question 12

Sediment is carried only a few centimeters from where it was picked up.

True

False

Question 13

Water is a significant factor in changing Earth's surface.

True

False

Question 14

Sediment transport is a key component of the erosion process.

True

False

Question 15

Weathering contributes to the change of landforms.

True

False
