Matter
What is Physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy?
Erosion
What is The process of eroding or being eroded by wind, water, or other natural agents?
Tectonic Plate
What is A theory in geology: the lithosphere of the earth is divided into a small number of plates which float on and travel independently over the mantle and much of the earth's seismic activity occurs at the boundaries of these plates?
Law Of Conservation Of Matter
What is In a fundamental principle of classical physics that matter cannot be created or destroyed in an isolated system?
Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus with a very small contribution from the orbiting electrons.
What is the nucleus of an atom?
Atom
What is Atoms as a source of nuclear energy?
Geosphere
What is Any of the almost spherical concentric regions of matter that make up the earth and its atmosphere, as the lithosphere and hydrosphere?
Deposition
What is The action of deposing someone, especially a monarchy?
Photosynthesis
What is The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct?
What particles are in the nucleus of an atom?
Element
What is A part or aspect of something abstract, especially one that is essential or characteristic?
Lithosphere
What is The rigid outer part of the earth, consisting of the crust and upper mantle?
Evaporation
What is The process of turning from liquid into vapor?
Eutrophication
What is Excessive richness of nutrients in a lake or other body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen?
A measure of acidity or alkalinity of water soluble substances
What does pH describe?
Nucleus
What is The central and most important part of an object, movement, or group, forming the basis for its activity and growth?
Biosphere
What is The regions of the surface, atmosphere, and hydrosphere of the earth?
Landform
A natural feature of the earth's surface.
Decomposer
What is An organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material?
The process of eroding or being eroded by wind, water, or other natural agents.
What is erosion?
Molecule
What is A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction?
Atmosphere
What is the envelope of gases surrounding the earth or another planet?
Groundwater
What is Water held underground in the soil or in pores and crevices in rock?
Nitrogen Fixation
What is The chemical processes by which atmospheric nitrogen is assimilated into organic compounds, especially by certain microorganisms as part of the nitrogen cycle?
A fundamental principle of classical physics that matter cannot be created or destroyed in an isolated system.
What is the law of conservation of matter?
