Let's solve the worksheet step by step.

Q.1. Fill in the blanks with suitable words.
a) ________ is the process of breaking rocks into smaller pieces over time.
✔ Answer: Weathering
👉 *Explanation:* Weathering refers to the physical, chemical, or biological breakdown of rocks at or near the Earth’s surface without moving them. This happens due to factors like temperature changes, water, ice, and living organisms.
---
b) The movement of rock particles from one place to a new location by ice, wind, water, or gravity is called ________.
✔ Answer: Erosion
👉 *Explanation:* Erosion is the process where weathered materials (like rock fragments or soil) are transported from one place to another by natural agents such as water, wind, ice, or gravity.
---
c) Removing plants covering the soil cause soil erosion to ________.
✔ Answer: increase
👉 *Explanation:* Plants help hold soil in place with their roots. When they are removed (e.g., through deforestation or farming), the soil becomes more vulnerable to being carried away by wind or water, thus increasing erosion.
---
d) ________ is the dropping off and layering of sediments in a new location.
✔ Answer: Deposition
👉 *Explanation:* Deposition occurs when eroded materials are dropped or deposited in a new location. For example, rivers deposit sediments to form deltas, or wind deposits sand to create dunes.
---
Q.2. Use the words in the box below to label the following image.
Words:
-
Erosion
-
Deposition
-
Weathering
Now, let’s analyze the diagram:
#### 1.
"Breaks It" – Breaking Down of Material (Wind, Water, Ice)
✔ Label this part as:
Weathering
👉 *Why?* This shows rocks being broken down by natural forces like wind, water, and ice — which is the definition of weathering.
#### 2.
"Takes It" – The Movement of the Material (Wind, Water, Ice, Gravity)
✔ Label this part as:
Erosion
👉 *Why?* This shows the transport of broken-down material from one place to another — that’s erosion.
#### 3.
"Drops It" – The Dropping of Sediment in a New Location (Sand Dunes, New Islands)
✔ Label this part as:
Deposition
👉 *Why?* Sediments are being dropped and layered in new areas like sand dunes or islands — this is deposition.
---
✔ Final Answers:
Q.1:
a)
Weathering
b)
Erosion
c)
increase
d)
Deposition
Q.2:
- "Breaks It" →
Weathering
- "Takes It" →
Erosion
- "Drops It" →
Deposition

This cycle illustrates the three key processes in landscape change:
Weathering → Erosion → Deposition,
which together shape Earth’s surface over time.
