Nebular Theory
Swirling Cloud of Star Dust
Rotating Cloud Flattens into a Disk
Condensation and Accretion
Once a protostar has become a hydrogen-burning star, a strong stellar wind forms, usually along the axis of rotation. Thus, many young stars have a bipolar outflow, a flow of gas out the poles of the star. This is a feature which is easily seen by radio telescopes. This early phase in the life of a star is called the T-Tauri phase.
Planetary Differentiation
During the time of partial melting, all the terrestrial planets separated into three layers of differing physical and chemical composition.
• Crust - outer layer
• Mantle - middle layer
• Core - center
Earth System ScienceThe Earth can be divided into individual
parts (systems) to be studied, but it is
recognized that each part interacts with many
other parts.
The boundaries of a system can bedefined however you want.
Systems are defined by how energy andmatter cross the boundaries.
3 Types of Systems
Isolated - no mass transfer
- no energy transfer
Closed - no mass transfer
- energy transfer
Open - mass transfer
- energy transfer
