Introduction to ES

QuestionAnswer
What is astronomy The study of the universe. Because Earth is related to all other objects in space, it is very helpful in probing the origins in our own environment.
What is the atmosphere One of the main things that allows us to live on planet Earth; a gaseous layer that surrounds the planet. Without it, many of the processes and interactions that make the surface such a dynamic place would not occur.
What is the biosphere It contains all of life on Earth. It is gathered close to the surface in a zone witch extends from the ocean floor upward for several kilometers into the atmosphere.
What is a closed system A self-contained system with regard to matter. A car's cooling system is an example of one. No matter enters or leaves a one, although, energy moves freely in and out of one.
What is the core A dense inner sphere; one of the three principle regions lying beneath the atmosphere and ocean.
What is the crust The light and very thin outer layer of the Earth. It is its thinnest beneath the ocean, and its thickest where continents exist.
What is Earth Science The name for all sciences that collectively seek to understand Earth and its neighbors in space. It includes the studies of geology, oceanography, meteorology, and astronomy.
What is Earth system science The attempt to study Earth as a system made of numerous subsystems, rather than looking through the limited lens of only one of the traditional sciences.
What is an Environment It refers to everything that surrounds and influences an organism. Some social, some biological, and others non-living.
What is geology It simply means "study of Earth". It is traditionally divided into two areas, being physical and historical. Physical examines the materials composing Earth. Historical is to understand the origin of Earth.
What is the hydrosphere All the water on Earth's surface, such as oceans and lakes, and even water off the surface that has been evaporated into the atmosphere.
What is a hypothesis An untested explanation for how or why things happened in the manner observed. It's made once facts have been gathered and principles have been formulated to describe a natural phenomenon.
What is the lithosphere The rigid outer later that includes the crust and uppermost mantle.
What is the mantle One of the three principle regions of the earth, and is less dense than the core.
What is meteorology The study of the atmosphere and the processes that produce weather and climate.
What is a model It is usually used as a synonym for the word hypothesis, but actually is a less precise term because it is sometimes used to describe a scientific theory as well.
What is the nebular hypothesis It suggests that the bodies of our solar system evolved from an enormous rotating cloud called the solar nebula
What are negative feedback mechanisms They work to maintain the system as it is, or to "maintain the status quo"
What is a nonrenewable resource A resource in which the processes that create them are very slow and take millions of years to accumulate.
What is oceanography It includes the study of the composition and movements of seawater, as well as coastal processes, seafloor topography, and marine life.
What is an open system A system in witch both energy and matter flow into and out of the system.
What is a paradigm A theory that is extensively documented and held with a very high degree of confidence. It explains a large number of interrelated aspects of the natural world.
What is the physical environment It includes water, air, soil, and rock, as well as conditions such as temperature, humidity, and sunlight.
What is are positive feedback mechanisms Mechanisms that enhance or drive change.
What is a renewable resource A resource that can be replenished over relatively short time spans.
What is a system Any size group of interacting parts that form a complex whole.
What is a theory A well-tested and widely accepted view that the scientific community agrees best explains certain observable facts.
