What is Big Idea 5?

Big Idea 5: To understand (deep) time and the scale of space, models and maps are necessary. The use of models is fundamental to all of the Earth sciences.

What are the 4 big ideas of science?

All material in the Universe is made of very small particles. Objects can affect other objects at a distance. Changing the movement of an object requires a net force to be acting on it. The total amount of energy in the Universe is always the same but energy can be transformed when things change or are made to happen.

How was the Earth formed 4.6 billion years ago?

The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing planets, including one last giant impact that threw enough rock, gas, and dust into space to form the moon.
