Question Answer
Astronomy Study of objects beyond Earth's atmosphere
Meteorology Study of the air that surrounds our planet Weather and the forces that cause it
Geology Study of materials that make up Earth and the processes that form and change these materials
Oceanography Study of Earths oceans and the creatures that live there
Climatology Study of weather patterns over a long period of time Effects human activities have on weather and climate
Paleontology Study of the remains of organisms that once lived on Earth
Hydrology Study of water flow on and below Earth's surface
Ecology study of habitats of organisms and how organisms interact with each other and their environment
Geochemistry Earth's composition and the processes that change it
Tectonics Effects of internal processes on Earth's surface
Lithosphere The rigid outer shell of the planet Includes the crust and solid part of mantle Oceanic Crust: Basalt Continental crust: Granite
Asthenosphere Partially molten and flows like a soft plastic Part of mantle
Core Outer: liquid Inner: solid iron and nickel
hydrosphere The water in Earth's oceans, seas, lakes, rivers, and glaciers 97% saltwater 3% freshwater (75% in glaciers)
Atmosphere Blanket of gases that surround our planet Necessary for: 1.Respiration of living things 2. Protection from Sun's radiation 3. Keeps temperature suitable for life
Biosphere Includes all organisms on Earth as well as the environments in which they live
Technology The application of scientific discoveries
Scientific Method 1. Formulate a question 2. Research the question 3. Form a hypothesis 4. Conduct an experiment 5. Analyze data 6. Draw conclusions 7. Communicate results
hypothesis a suggested explanation for an observation
independent variable the factor that is manipulated
dependent variable a factor that can change if the independent variable changes
control a factor that stays constant or does not change Used to show that the result of an experiment is actually the result of the condition being tested
