Geography Grade 9 Term 3 2022 Question Paper

ⓘ Below are Question 1 explained answers by CAPS AI (supervised by Geography(SS) Teachers)

QUESTION 1: MULTIPLE CHOICE (1.1)

1.1.1 A. weathering
→ Weathering is the process that breaks down rocks into smaller pieces.

1.1.2 C. oxidation
→ Oxidation is a chemical process involving iron and oxygen, causing rusting (reddish color).

1.1.3 C. exfoliation
→ Exfoliation causes rocks to peel like onion layers due to temperature changes.

1.1.4 C. Expands
→ When water freezes in cracks, it expands and breaks the rock.

1.1.5 D. frost shattering
→ Frost shattering is physical, not chemical weathering.

QUESTION 1.2: TRUE or FALSE (Image-based)

Refer to the two diagrams (A and B) in the image:

1.2.1 TRUE – Both diagrams show physical weathering: exfoliation and frost action.

1.2.2 TRUE – Diagram A shows exfoliation (onion skin peeling due to heating and cooling).

1.2.3 FALSE – Frost action (Figure B) needs cold climates, not warm.

1.2.4 TRUE – Exfoliation happens in hot, dry areas like deserts in South Africa.

1.2.5 FALSE – Weathering breaks down material; erosion moves it.

QUESTION 1.3: Differentiate between weathering and deposition

Weathering is the breakdown of rocks into smaller particles through physical, chemical, or biological processes.
Deposition is the dropping off or laying down of sediment carried by wind, water, or ice when the transporting agent loses energy.

QUESTION 1.4: Sea Features (Image-based)

1.4.1 Label the marine erosion features (based on typical features):

• (A) Cliff

• (B) Wave-cut platform

• (C) Sea cave

• (D) Stack

1.4.2 Main feature of deposition by the sea:
→ The sea deposits materials like sand and pebbles, forming beaches, spits, and sandbars.
