A student expectation is directly related to the knowledge and skills statement, is more specific about how students demonstrate their learning, and always begins with a verb. Student expectations are further broken down into their component parts, often referred to as “breakouts.”
Vertical alignment shows student expectations in the same subject area at different grade levels that are related to or build upon one another.
Patterns are regular sequences that can be found throughout nature.
Geologic events occur based on patterns in the movement and type of crust at plate boundaries.
Cause-and-effect relationships are relationships between two or more variables or phenomena whereby one variable or event leads to a predictable response. Events have causes—sometimes simple, sometimes multi-faceted.
Due to the movement of the plates (cause), earthquakes occur (effect). Mountain building (effect) occurs when tectonic plates move toward each other at convergent boundaries (cause). Ocean basin formation (effect) occurs when tectonic plates diverge (cause).
Matter and energy are conserved, changing forms but maintaining quantities. Energy flows within a system or between systems through transfers and transformations. Matter is cycled within systems through physical and chemical processes.
The flow of energy in the mantle's convection currents drives the movement of tectonic plates.
Stability describes a system that does not change at the observed scale. In a stable system, a small disturbance will die out and the system will return to a stable state. Change in the system can come from modifying a factor or condition.
Stable convection currents in the mantle cause tectonic plate motion (change). Earthquakes, mountain building, and volcanic eruptions are products of collisions between plates.
