| Question | Answer |
|---|---|
| What is the definition of astronomy? | Astronomy is the study of the universe. |
| What is the definition of atmosphere? | The atmosphere is a life-giving gaseous envelope that surrounds the Earth. It provides the air we breathe as well as protects us from the Sun's heat and radiation. |
| What is the definition of biosphere? | The biosphere includes all life on Earth. The Earth's biosphere is located from the ocean floor into the atmosphere. |
| What is the definition of closed system? | A closed system is a system that is self contained. Energy within the system moves freely but no matter enters or leaves the system. Ex. In a car's cooling system, fluid does not leave the system. |
| What is the definition of core? | The Earth's core is a dense inner sphere, located in the most center part of the Earth. |
| What is the definition of crust? | The Earth's crust is the thinnest, outer-most layer of the Earth. It is thinnest beneath oceans and thickest underneath continents. |
| What is the definition of Earth Science? | Earth Science is the name for all science subjects that work together to understand Earth and it's nearby celestial bodies. It includes geology, oceanography, meteorology and astronomy. |
| What is the definition of Earth system science? | Earth system science is how scientists attempt to understand how individual components or subsystems of Earth; land,water, air and life forms, interact as a system. |
| What is the definition of environment? | Environment refers to everything that surrounds and influences an organism. Some factors are logical and social while others are nonliving. |
| What is the definition of geology? | Geology is the study of Earth that can be divided into two sections: physical and historical. Physical geology examines the materials composing earth while historical geology aims to understand the origin of earth and how it developed over time. |
| What is the definition of hydrosphere? | The hydrosphere is a dynamic mass of liquid that is continually on the move, evaporating from the oceans to the atmosphere , precipitating to the land and running back to the ocean again. |
| What is the definition of hypothesis? | A hypothesis is an untested explanation developed by a scientist in attempt to explain a natural phenomena. |
| What is the definition of lithosphere? | The Earth's lithosphere is the rigid outer layer that includes the crust and upper most mantle. |
| What is the definition of mantle? | The Earth's mantle is less dense than the core and lays underneath the crust. |
| What is the definition of meteorology? | Meteorology is the study of the atmosphere and the processes that produce weather and climate. |
| What is the definition of model? | The term model, often used with hypothesis is a less accurate term used to describe a scientific theory. |
| What is the definition of nebular hypothesis? | The nebular hypothesis suggests that the bodies of our solar system evolved from an enormous rotating cloud called the solar nebula, composed mostly of hydrogen and helium, with a small percentage of the heavier elements. |
| What is the definition of negative feedback mechanism? | Negative feedback mechanisms resist change and stabilize natural systems. Ex. The human body cooling system works to stabilize our body temperature. |
| What is the definition of nonrenewable resource? | A nonrenewable resource is a resource that cannot be replenished. Some examples of nonrenewable resources are important metals like iron, aluminum and copper. Also important fuels: oil, natural gas and coal. |
| What is the definition of oceanography? | Oceanography involves all sciences that study oceans and their aspects and relationships. It studies the movements of seawater, coastal processes, seafloor topography and marine life. |
| What is the definition of open system? | In an open system both energy and matter flow into and out of the system. Most natural systems are open systems. Ex. in a river system the amount of water in the channel can change, also varying the amount of sediment in the river. |
| What is the definition of paradigm? | A paradigm is a theory that is extensively documented and is held with high degree in the science community. |
| What is the definition of physical environment? | Physical environment is the term that describes the importance of water, air, soil, and rock including temperature, humidity and sunlight. |
| What is the definition of positive feedback mechanism? | Positive feedback mechanisms enhance and drive change. |
| What is the definition of renewable resource? | A resource that is considered renewable can be replenished over a short period of time. An example of a renewable resource are plants animals, natural fiber, forest products, moving water, wind and sunlight. |
| What is the definition of system? | A system can be any size group of interacting parts that form a complex whole. Most natural systems are driven by sources of energy that move matter or energy from place to place. |
| What is the definition of theory? | A scientific theory is a well-tested and widely accepted view that the scientific community agrees best explains certain observable facts. |
