Class Introduction
A marine ecosystem is a community of organisms interacting with each other and the ocean environment.

The solar system began as a huge cloud of gas and dust called
Solar Nebula
Difference between rotation and revolution
Rotation: Spin on axis
Revolution: Orbit around sun
I am made mostly of hydrogen and helium.
Sun
A living part of an ecosystem.
I cause day and night
rotation
how long is 1 rotation?
how long is 1 revolution?
24 hours or 1 day
365 days or 1 year
Where does nuclei fusion happen?
Core
Name two abiotic factors.
Fish and coral.
Sunlight and temperature.
This is the 'balanced point or shared center of mass' between the sun and the Earth that each revolve around. The bigger the object, the closer this is to that object
Barycenter
the regular rise and fall of ocean water
tides
How does the sun produce energy?
Nuclear fusion occurs in the sun's core. Hydrogen nuclei combine to form helium and energy is released.
Organisms that make their own food through photosynthesis.
what are the 4 rocky planets in the order from closest to the sun and tell why they are called rocky planets.
mercury, venus, earth, mars. They are called rocky planets because they have solid surfaces made mostly of rock and metal.
Why is sunlight important to life on Earth
Drives water cycle, Heats Earth’s surface, Regulates temperature, Drives atmosphere, Drives weather, Powers photosynthesis
three kinds of electromagnetic radiation
visible, infrared, ultraviolent (UV)
The Sun and everything that travels around it
Solar System
This Law states that the further a planet is from the sun, the slower it will rotate, while the closer the planet, the faster it will rotate.
Kepler's 2nd Law of Equal Areas
How does Earth protect us from harmful parts of the sun's energy?
The atmosphere and ozone layer protect life by blocking harmful UV radiation.
