Self Assessment: Learning Target #1: Identify Earth's spheres and describe how they interact
a I can name and describe Earth's spheres and give a detailed example of how they interact
b I can name Earth's spheres and give an example of how they interact
c I can name Earth's spheres but need help to describe how they interact
d I need help naming Earth's spheres and how they interact

Answer 1

To help you assess your understanding of Earth's spheres and their interactions, here’s a brief overview of each sphere and how they might interact. You can use this information to determine which learning target aligns best with your current comprehension.

### Earth's Spheres:

1. **Lithosphere**: The solid outer part of the Earth, including rocks, soil, and landforms.
2. **Hydrosphere**: All the water on Earth, including oceans, rivers, lakes, and glaciers.
3. **Atmosphere**: The layer of gases surrounding the planet, which is crucial for weather and climate.
4. **Biosphere**: All living organisms on Earth, including plants, animals, and microorganisms.

### Interactions:

1. **Lithosphere and Hydrosphere**: Water from the hydrosphere erodes rocks in the lithosphere, shaping landscapes and creating features like valleys and canyons. For example, river water flows over rock and soil, gradually carving out a riverbed.

2. **Hydrosphere and Atmosphere**: Water evaporates from the surface of oceans and lakes, entering the atmosphere as water vapor. This process is essential for the water cycle, facilitating precipitation that nourishes plant life in the biosphere.

3. **Atmosphere and Biosphere**: Plants in the biosphere absorb carbon dioxide from the atmosphere during photosynthesis, releasing oxygen as a byproduct, which is essential for animal life.

4. **Lithosphere and Biosphere**: Soil in the lithosphere provides nutrients for plants, which are the basis of most food chains in ecosystems within the biosphere. For instance, fertile soil supports agriculture.

5. **Biosphere and Hydrosphere**: Animals rely on water from the hydrosphere for drinking and habitats. Aquatic ecosystems, like coral reefs, also support diverse life forms, emphasizing the interconnectedness of water and life.

### Self-Assessment:

- **If you can name and describe Earth's spheres and give a detailed example of how they interact**, you align with **Learning Target #1a**.
- **If you can name Earth's spheres and give an example of how they interact**, you align with **Learning Target #1b**.
- **If you can name Earth's spheres but need help to describe how they interact**, you align with **Learning Target #1c**.
- **If you need help naming Earth's spheres and how they interact**, you align with **Learning Target #1d**.

Review the content above and assess your understanding based on these criteria. This will help you identify which learning target you have achieved and where you may need additional focus or support.
