Key Idea #1 As scientists seek to understand the natural world, they use skills such as observing, inferring, and predicting.
Science - A way of learning about the natural world and knowledge gained through a process
Observing - Using your senses to gather information
Predicting - Making a forecast of what will happen in the future based on past evidence
Inferring - making an educated guess based on observation
Scientific Inquiry - asking questions about what you observe
Key Idea #2 - The Earth has 4 main parts
1. Atmosphere= Outermost; mixture of gases -> Nitrogen & Oxygen
2.Hydrosphere= Hydrosphere->water=anything with water;oceans,lakes,rivers,ice
3.Lithosphere= solid, rocky outer layer; our continents & smaller landmasses
4.Biosphere= all living thing; extends into the other three
Key Idea#3 The topography of an area includes:
1) Elevation - The height above sea level of a pt. on Earth's surface
2) Relief - The difference in elevation between highest & lowest parts
3)Landforms - A feature of topography such as hills or valley.
Key Idea #4 There are three main types of landforms
1)Plains - Nearly flat on gently rolling land with relief
2)Mountains - High elevation & high relief; Mountain range, Rocky Mountains = Mountain Belt
3)Plateaus - High elevation & and or less surface
