What is Earth Science?
What is the study of objects beyond Earth's atmosphere?
Astronomy
What is a substance that cannot be broken down into simpler substances by physical or chemical means?
Element
a naturally occurring, inorganic solid with specific chemical composition and a definite crystalline structure.
mineral
rocks that form from small pieces of rock that are moved and deposited by water, wind, glaciers, and gravity.
sedimentary rocks
Biosphere
What is the study of materials that make up Earth and the processes that form and change these materials, and the history of the planet and its life-forms since its origin?
Geology!!!
What is composed of two or more atoms held together by covalent bonds.
Molecule
a measure of how easily a mineral can be scratched
hardness
rocks that form when lava or magma cools and crystalizes
igneous rocks
Sphere that contains the part of Earth from its surface to its center is known as the
Geosphere
What is the study of the interactions of humans with the environment?
Environmental Science
What is a substance that is composed of atoms of two ore more different elements that are chemically combined.
Compound
valuable minerals that are prized for their rarity and beauty.
gem
rocks that form when temperature and pressure combine and change the texture, mineral composition, or chemical composition of a rock without melting it
metamorphic rocks
Sphere of Earth that includes gases surrounding Earth that contains about 78% nitrogen, 21% oxygen, and 1% other gases such as argon, carbon dioxide, and water vapor
Atmosphere
What is the study of the atmosphere?
Meteorology
What is an atom of an element that has a different mass number than the element but the same chemical properties?
Isotope
Contains a valuable substance that can be mined at a profit
ore
large belts of metamorphic rock created when temperature and pressure affect large regions of Earth's crust
regional metamorphism
Sphere of Earth that contains all the water in Earth's oceans, lakes, seas, rivers, and glaciers plus all the water in the atmosphere
Hydrosphere
What is the study of Earth's oceans including the creatures that inhabit its waters, its physical and chemical properties, and the effects of human activities?
Oceanography
What is an atom that has gained or lost an electron?
Ion
Classification of minerals that contain silicon and oxygen, and usually one or more additional elements
silicate
sequential, predictable, dual-branched pattern in which minerals crystallize from cooling magma
Bowen's reaction series
The natural process where certain atmospheric gases absorb heat radiating off the planet's surface and prevents this heat from being lost to space, which helps keep Earth warm enough to sustain life
Greenhouse effect
