Card preview (24)
The study of forces and processes that cause the atmosphere to change and produce weather. **these scientists study the forecast of weather and the changes in weather over time
Meteorology
The study of objects beyond Earth’s atmosphere **these scientists study the universe and everything in it
Astronomy
The study of the materials that make up the Earth, the processes form and change these materials, and the history of the planet and it’s life-forms since it’s origin is the branch of Earth Science. **these scientists identify rocks, study glacial movements, and earths 4.6-billion-year history
Geology
The study of Earth’s oceans, which cover nearly 3/4 of the planet **these scientists study the creatures that inhabit salt water, measure different physical and chemical properties of the oceans, and observe various processes in these bodies of water.
Oceanography
The study of the interactions of organisms and their surroundings. **these scientists study how organisms impact the environment both positively and negatively
Environmental Science
Geosphere, atmosphere, hydrosphere, and biosphere.
Earth’s Systems
The area from the surface of the Earth down to it’s center. **three main parts: crust, mantle, core
Geosphere
The blanket of gases that surrounds our planet. • 78% nitrogen • 21% oxygen
Atmosphere
All the water on Earth, including the water in the atmosphere. • 97% is salt water • 3% is fresh water
Hydrosphere
All organisms on Earth as well as the environments in which they live.
Biosphere
The application of scientific discoveries Example: ski goggles, freeze-dried foods
Technology
A series of problem-solving procedures that help scientists conduct experiments.
Scientific Method
a testable explanation of a situation that can be supported or disproved by careful procedures.
Hypothesis
The part of the experiment YOU change. You are in control.
Independent variable
What you are measuring. Data
Dependent variable
Our basis for comparison. *not changed
Control
Things remain the same through each trial of the experiment.
