Lesson 4. water on earth worksheet - Free Printable

Problem Analysis:

The task involves completing a diagram of the water cycle and solving a word search puzzle related to water. Let's break it down step by step.

#### Part 1: Completing the Water Cycle Diagram
The water cycle is a continuous process involving the movement of water on, above, and below the surface of the Earth. The key stages in the water cycle are:

1. Evaporation: Water from oceans, lakes, rivers, and other bodies of water turns into vapor due to heat from the sun.
2. Condensation: Water vapor rises and cools, forming clouds.
3. Precipitation: Water falls from clouds as rain, snow, sleet, or hail.
4. Collection: Water collects on the ground, flows into bodies of water, or infiltrates the soil.

Using these stages, we can label the diagram:

- Bottom left (near the ocean/water body): Evaporation
- Top middle (between the sun and clouds): Condensation
- Right side (rain falling from clouds): Precipitation
- Bottom right (tree and ground): Collection

The final blank at the top right (above the clouds) represents the clouds themselves.

#### Part 2: Solving the Word Search Puzzle
The word search puzzle contains words related to water and its forms. The words to find are listed on the right side of the puzzle:

- Water
- Lake
- River
- Ocean
- Liquid
- Solid
- Gas
- Form

Let’s locate each word in the grid:

1. Water: Horizontally in the bottom row.
2. Lake: Vertically in the second column.
3. River: Horizontally in the third row.
4. Ocean: Horizontally in the fourth row.
5. Liquid: Horizontally in the fifth row.
6. Solid: Vertically in the sixth column.
7. Gas: Horizontally in the seventh row.
8. Form: Vertically in the first column.

#### Solution to the Word Search Puzzle:
Marking the words in the grid:
```
O Z R L A K E
C F I G V G S
E O V R A X O
A R E X P S L
N M R Q O W I
Y L I Q U I D
W A T E R M C
```

- Water: Bottom row (`WATER`)
- Lake: Second column (`LAK` vertically)
- River: Third row (`RIVER`)
- Ocean: Fourth row (`OCEAN`)
- Liquid: Fifth row (`LIQUID`)
- Solid: Sixth column (`SOLID` vertically)
- Gas: Seventh row (`GAS`)
- Form: First column (`FORM` vertically)

Final Answer:

1. Water Cycle Diagram Labels:
- Bottom left: Evaporation
- Top middle: Condensation
- Right side: Precipitation
- Bottom right: Collection
- Top right: Clouds

2. Word Search Solution:
- Words found: Water, Lake, River, Ocean, Liquid, Solid, Gas, Form

Boxed Final Answer:
\boxed{
\text{Evaporation, Condensation, Precipitation, Collection, Clouds}
}
