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

Question 1

What initial process involves natural agents causing rocks to disintegrate?

Breaking down rocks.

Mineral synthesis.

Rock compaction.

Crystal growth.

Question 2

What is the relationship between erosion and deposition?

Erosion moves sediments, and deposition lays them down.

Erosion stops deposition from occurring.

Deposition causes rocks to break down.

They are unrelated processes.

Question 3

What is the primary characteristic that defines mechanical weathering?

It involves the transportation of eroded materials by natural forces.

It breaks rocks into smaller pieces without changing their chemical composition.

It alters the mineral structure of rocks through chemical reactions.

It is primarily responsible for forming new types of rocks from existing ones.

Question 4

What is the primary process by which solid rocks and other Earth materials are broken down into smaller pieces?

Deposition

Sedimentation

Weathering

Erosion

Question 5

Which landform is specifically mentioned as being formed by a river depositing sediment where it meets the sea?

A mountain range

A canyon

A delta

A volcano

Question 6

Weathering is a fundamental process within the rock cycle, contributing to the formation of sediments.

True

False

Question 7

What happens to soil on hilly farmland due to rain?

Rain washes the soil downhill little by little.

Rain compacts the soil in place.

Rain causes the soil to become more fertile.

Rain pushes the soil uphill.

Question 8

How do the roots of trees and other plants contribute to rock breakdown?

They grow into cracks in rocks and expand, eventually breaking the rock.

They secrete acids that dissolve the rock material.

They shield rocks from wind and water, preventing weathering.

They absorb minerals from the rock, causing it to crumble.

Question 9

Sediments can build new landforms.

False

True

Question 10

Scientific inquiry encourages individuals to share ideas even if they are not entirely certain about them.

False

True

Calculating your results... almost there!
