The Water Cycle - A detailed educational diagram explaining the natural process of water movement through evaporation, condensation, precipitation, and collection.

Here is the step-by-step solution to fill in the blanks on the water cycle diagram.

Step 1: Identify the process where water turns into vapor from the ocean.
Look at the bottom left of the diagram. There is a large body of water (the sea) and an arrow pointing up towards the sun. The text says, "Water from the sea... is warmed by the Sun." When the sun heats water, it turns into gas. This process is called evaporation.

Step 2: Identify what forms when water vapor rises and cools.
Follow the red arrow moving up from the sea into the sky. The text explains that warm air rises and then cools down. When water vapor cools, it turns back into tiny liquid droplets that form clouds. This process is called condensation. So, the blank inside the cloud should be condensation.

Step 3: Identify how water falls from clouds to the ground.
Look at the arrows coming down from the cloud onto the mountains and trees. The text says, "When the air is cold enough, these droplets will fall as rain or snow." Water falling from the sky is called precipitation.

Step 4: Identify how plants release water.
Look at the trees on the right side of the diagram. There are small arrows pointing up from the leaves. The text mentions that water moves through plants and leaves and evaporates into the air. This specific type of evaporation from plants is called transpiration.

Step 5: Identify water flowing over the land surface.
Look at the arrow flowing down the side of the mountain hill into the river. The text describes water running off the land into rivers and lakes. This is known as surface run-off.

Step 6: Identify water soaking into the ground.
Look at the arrow pointing down into the soil/ground under the grass. The text says some water soaks into the soil to become groundwater. The process of water soaking into the ground is called infiltration.

Step 7: Identify the water stored underground.
Look at the blank space underneath the ground layer. The text refers to this as "groundwater" which flows slowly to recycle water. Therefore, the label for the water under the ground is ground water store.

Final Answer:

Here are the correct words for each box in the diagram, going generally from left to right and top to bottom:

1. evaporation (Box above the sea/ocean)
2. condensation (Box inside the cloud)
3. precipitation (Box near the rain falling on the mountain)
4. transpiration (Box near the trees releasing water vapor)
5. surface run-off (Box showing water flowing down the hill)
6. infiltration (Box showing water soaking into the soil)
7. ground water store (Box underground)
