تدريب عام: Unit 4 : Concept 4.1 Breaking Down and Moving Rocks (Science) - Primary 4 - Science

السؤال 1

What initial process involves natural agents causing rocks to disintegrate?

Crystal growth.

Mineral synthesis.

Rock compaction.

Breaking down rocks.

السؤال 2

What is the relationship between erosion and deposition?

They are unrelated processes.

Erosion stops deposition from occurring.

Erosion moves sediments, and deposition lays them down.

Deposition causes rocks to break down.

السؤال 3

What is the primary characteristic that defines mechanical weathering?

It involves the transportation of eroded materials by natural forces.

It alters the mineral structure of rocks through chemical reactions.

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

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

السؤال 4

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

Sedimentation

Weathering

Deposition

Erosion

السؤال 5

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

A canyon

A mountain range

A volcano

A delta

السؤال 6

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

False

True

السؤال 7

What happens to soil on hilly farmland due to rain?

Rain causes the soil to become more fertile.

Rain pushes the soil uphill.

Rain compacts the soil in place.

Rain washes the soil downhill little by little.

السؤال 8

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

They shield rocks from wind and water, preventing weathering.

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

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

They secrete acids that dissolve the rock material.

السؤال 9

Sediments can build new landforms.

True

False

السؤال 10

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

False

True
