# SES1: Earth Systems Composition

Obtain, evaluate, and communicate information to investigate the composition and formation of Earth systems, including the Earth's place in the solar system.

- Subject: Science
- Appears in: High School, https://georgiahomeroom.org/standards/science/high-school.md

## Expectations

- **SES1.a**: Construct an explanation of the origins of the solar system from scientific evidence including the composition, distribution and motion of solar system objects.
- **SES1.b**: Ask questions to evaluate evidence for the development and composition of Earth's early systems, including the geosphere (crust, mantle and core), hydrosphere and atmosphere.
- **SES1.c**: Develop a model of the physical composition of Earth's layers using multiple types of evidence (e.g., Earth's magnetic field, composition of meteorites and seismic waves).

## Georgia Milestones coverage

No Georgia Milestones blueprint cites this standard.
