 The layer of gases that surround the Earth is called the ATMOSPHERE The two most abundant gases in the atmosphere are NITROGEN AND OXYGEN The form of oxygen with three oxygen atoms in each molecule is called OZONE Because the Earth's atmosphere traps energy from the sun, water exists as a LIQUID The formula for density is DIVIDE MASS BY VOLUME As you increase the eleveation, air pressure PUSHES DOWN ON YOU Te lowest part of the atmosphere is the TROPOSPHERE All weather occurs in this part of the atmosphere THE TROPOSPHERE The part of the atmosphere that contains the ozone THE STRATOSPHERE The part of the atmosphere where most of the meteors burn up in the atmosphere THE MESOSPHERE The part of an experiment that is purposely changed is called the MANIPULATED VARIABLE The factor that may change in response to the manipulated variable is called the RESPONDING VARIABLE A possible explanation for a set of observations or answer to a sceintific question is called a HYPOTHESIS A summary of what you have learned from a scientific experiment is called a CONCLUSION A well-tested explanation for a wide range of observations or experimental results is called a THEORY Wave lenghts taht are a little bit shorter than visible light are called INFRARED Most of the energy that heats the Earth's atmosphere is INFRARED What is the greenhouse effect? The rise in temperature that the Earth experiences because of certain gases that are in the atmosphere How is heat transferred by convection? Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. How is heat transferred by conduction? Conduction is heat transfer by means of molecular agitation within a material without any motion of the material as a whole. If one end of a metal rod is at a higher temperature, then energy will be transferred down the rod toward the colder end because the higher speed particles will collide with the slower ones with a net transfer of energy to the slower ones. What is heat transfer by radiation? Radiation is heat transfer by the emission of electromagnetic waves which carry energy away from the emitting object. Wind pressures are caused by differences in AIR TEMPERATURE Land breezes occur because LAND COOLS FASTER THAN WATER What is the Coriolis Effect? HOW THE EARTH'S ROTATION AFFECTS THE WINDS Large clouds that produce thunderstorms are called CUMULONIMBUS CLOUDS Very high feathery clouds are called CIRRUS CLOUDS When a cold air mass overtakes a warm air mass the result is A COLD FRONT When a warm air mass and a cold air mass meet and neither can move the other the result is A STATIONARY FRONT The most dangerous part of the snowstorm is HIGH WINDS Scientists who study and predict the weather are called METEOROLOGISTS what is an isobarian isotherm? IT SHOWS LINES OF TEMPERATURE If a mineral is inorganic it means THAT IT NEVER LIVED If a mineral is organic it means THAT IT ONCE LIVED; THAT IT WAS ONCE ALIVE What is streak, luster and hardness? STREAK IS THE LINE THAT CAN BE WRITTEN WITH A ROCK. LUSTER IS HOW IT SHINES, AND HARDNESS IS HOW IT IS COMPARED WITH THE HARDNESS OR SOFTNESS OF OTHER ROCKS. THERE IS A SCALE FROM 1 TO 10 OF HARDNESS CALLED THE MOH'S SCALE What type of crystal is formed from slow cooling magma? LARGE CRYSTALS What type of crystal is formed from fast cooling magma? SMALL CRYSTALS A mineral that can be mined for profit is called AN ORE What is the hardest mineral on Moh's scale #10 - DIAMOND What is the softest mineral on Moh's scale? #1 - TALC What crystal shape is salt? SALT IS A CUBIC SHAPE An igneous rock that formed from lava that erupted onto the Earth's surface can be classified as AN EXTRUSIVE ROCK The most abundant intrusive rock in the continental crust is GRANITE Heat and pressure deep beneath the Earth's surface can change any rock into a METAMORPHIC ROCK To describe a rock's texture, geologists determine the size and shape of the rock's GRAINS Rocks that formed from cooling magma below the surface are called INTRUSIVE ROCKS An igneous rock that formed from lava that erupted onto the Earth's surface can be classified as EXTRUSIVE ROCK
