Universal laws of matter and energy establish the physical and chemical characteristics of the Earth and its atmosphere.

Interactions of matter and energy at the atomic level form a base for planetary phenomena.

IA

Law of conservation of matter: number and mass; kinetic molecular theory

Observable processes and events on Earth are explained by laws of physics and chemistry.

IB

Laws of conservation of momentum and energy, two-dimensional motion, laws of electricity and magnetism, kinetic molecular theory.

The Earth’s ecosystems are affected by changes in kinds and directions changes.

IC

Greenhouse effect, ozone layer, and photosynthetic-respiratory cycles

Disruptions of biological and ecological systems result when the Earth’s dynamic equilibrium shifts.

Semester 2

Impact of processes and changes in living systems on the Earth

Individuals, species populations, and communities are affected by environmental changes.
