Question
Step 1: Explore
Let’s start by identifying the factors that contribute to how water flows through a watershed. Review the lessons (and do some research, if needed) to answer the following questions in a new word processing document:
What is a watershed?
What is a continental divide and its role in a watershed basin?
How does water flow in a watershed?
What are some of the bodies of water that are included in a watershed?
How is water replenished and circulated back into a watershed?
What is an aquifer, and how does it eventually collect and store water?
Step 2: Illustrate a Cross-Section
Make a cross-section of a watershed that provides a two-dimensional slice of the Earth’s surface and the area below it. Illustrate and identify the following features:
Sources of water (including rainfall, groundwater, and surface water)
Continental divide (mountains)
The movement of surface and groundwater within the watershed
Choose what materials to use in creating your cross-section. You may decide to draw one by hand using art supplies or create one using graphic design or presentation software. It’s up to you!

## Step 1: Explore
### What is a watershed?
A watershed is an area of land that drains or channels rainfall and snowmelt into a common outlet, such as a river, lake, or ocean. Watersheds are defined by topographic boundaries, such as hills or mountains, which direct the flow of water. It plays a crucial role in managing water resources and maintaining water quality by filtering pollutants as water travels through various landscapes.
### What is a continental divide and its role in a watershed basin?
A continental divide is a natural boundary that separates the drainage basins of different continents or major regions. It determines the direction that water flows; water on one side of the divide flows towards one ocean or sea, while water on the other side flows towards another. This divide influences regional climates, weather patterns, and the distribution of ecosystems.
### How does water flow in a watershed?
Water flows through a watershed primarily through surface runoff and subsurface flow. Rainfall or snowmelt infiltrates the ground, replenishing groundwater supplies. Surface runoff occurs when water flows over the land and collects into streams and rivers. Gravity plays a significant role in directing this flow, leading water to lower elevations and eventually to larger bodies of water.
### What are some of the bodies of water that are included in a watershed?
A watershed includes various bodies of water such as:
- Rivers and streams
- Lakes and ponds
- Wetlands
- Reservoirs
- Groundwater systems, which can be accessed via wells or springs
### How is water replenished and circulated back into a watershed?
Water is replenished through the processes of precipitation (rain and snow) and infiltration, where water soaks into the ground replenishing aquifers and groundwater. Water circulation occurs through evaporation (turning liquid water into vapor), condensation (forming clouds), and precipitation, completing the water cycle. This continuous cycle ensures the maintenance of water availability in a watershed.
### What is an aquifer, and how does it eventually collect and store water?
An aquifer is a geological formation that can store and transmit water, typically consisting of permeable rock or sediment. Water enters an aquifer through the process of infiltration from the surface and can be stored there for extended periods. Aquifers can be recharged by precipitation, surface water, or other aquifers and serve as crucial sources of freshwater for various uses, including drinking water, irrigation, and industrial processes.

## Step 2: Illustrate a Cross-Section
For the cross-section of a watershed, please refer to the attached diagram (illustration and labeling).
### Cross-Section Features to Include:
1. **Sources of Water**:
- **Rainfall**: Shown as droplets falling onto the ground.
- **Groundwater**: Indicated by arrows moving through soil layers and into an aquifer.
- **Surface Water**: Rivers and streams depicted flowing across the landscape.
2. **Continental Divide**:
- Represented by mountain peaks or ridges, marked clearly as the boundary where water flows to different sides.
3. **Movement of Surface and Groundwater**:
- Surface runoff depicted with arrows directing the flow of water toward rivers.
- Groundwater flow illustrated with wavy arrows moving underground toward the aquifer.
### Materials for Cross-Section:
You can choose to create your cross-section using:
- Hand-drawn techniques with colored pencils or markers.
- Graphic design software such as Adobe Illustrator or Canva.
- Presentation software such as PowerPoint or Google Slides.
