Question
Astronomy A. light-year B. meteoroids C. planets D. stars The distance a beam of light travels in one year. Large globes of intensely heated gas, generating their own light. Normally very small solid objects that traverse space and usually are burned up before reaching earth. Large solid, approximately spherical masses, the most famous of which is earth, which revolve around our sun. Ecology, Pollution, and Energy A. biodegradable B. ecology C. endangered species D. environment E. extinct F. food chain G. geothermal H. habitat I. Kinetic energy J. nuclear energy K. photosynthesis L. pollutant M. recycling N. smog O. solar energy The knowledge or life science that studies how living things depend on each other and their environment. Any substance that can be decomposed by bacterial action. Energy produced by or coming from the sun. Energy in action. The total surroundings or all the conditions that effect the life and growth of living things. Heat energy coming from inside the earth. Heat from volcanoes or geysers. The energy released when atoms are split apart or fused together in atomic reactions. The place where a community of plants and animals lives: the place where some organism is usually found. In green plants, putting together food molecules with chlorophyll and the light energy from the sun. Substance or material that causes pollution. All the living things of a particular kind so few in number that they a threatened with extinction. A type of air pollution common around but not limited to cities. Organisms that once lived on earth but all of their kind have died out: a dead species. To use again and again: to collect waste materials such as water, glass, cans, and paper, and renew them for use by special processing. A series of food energy steps from plants to animals to other animals in a community of living things. Food relationships show where organisms get their food: each member on the chain feeds on the preceding link.Explanation / Answer
57)A. Light-Year.
a light year is 9.5 trillion meters so i would think about that muchyea besides that is light year.
58)D. stars
Large globes of intensely heated gas, generating their own light is stars.
59)B.meteoroids
Upon entering Earth's atmosphere, the small object starts to hit air particles, which exist in an increasing number per square foot as the object gets closer to Earth (air pressure). This creates friction and a great amount of kinetic energy, meaning the molecules within the object move faster and faster,until the molecular bonds begin to break, which is the visible phenomenon of the object burning up. The speed at which this happens depends on the chemical properties of the object, especially its density, as well as the object's velocity are Meteoroids.
60)C.planets
This would be the definition of a "planet", which are technically "satellites" of the Sun.
61) B.ecology
62)A.biodegradable
63)O.solar energy
64)I.kinetic energy
65)D.environment
66)G.geothermal
67)J.nuclear energy
68)H.habitat
69)K.photosynthesis
70)L.pollutant
71)C.endangered species
72)N.smog
73)E.extinct
74)M.recycling
75)F.food chain
