Why is groundwater able to move thousands of tons of rock and sediment? The flowing water easily weathers the rock The warmer water has more thermal energy which allows it to break down the rock The water is slightly acidic which dissolves the rock The water violently crashes against the rock breaking off large chunks Which rock types is especially susceptible to groundwater erosion? Limestone Basalt Obsidian Granite Matching Groundwater Erosion Land Forms Stalagmites Sediment deposits formed on cave floors Stalactites Sediment deposits formed on cave ceilings Sinkhole Round depression formed when a cave roof collapses pH Scale Used to measure how acidic or basic a solution is Karst Topography Irregular landscapes formed by groundwater erosion Sorting States of Matter Solid Fixed shaped Does not take the shape of its container Most dense state of matter (if volumes are equal) Particles vibrate in place Ex - Lego block Liquid Takes the shape of its container Particles flow around each other Particles are loosely packed Ex - Coffee Gas Takes the shape and fills its container Has the most thermal energy (if volumes are equal) Particles have a lot of space between them Ex - Air Changes in State Fill in the blanks with the various states of matter and changes in state. REMEMBER! All terms are in all lowercase. If you spell it wrong it marks it wrong!

Add cold Add heat Remove heat Remove cold What type of energy does a book sitting on a table have? (Choose the best answer) Potential Energy Kinetic Energy Electromagnetic Energy Mechanical Energy Sort the energy types and their examples Mechanical Energy The sum of all of the potential and kinetic energy of an object A rock rolling down a hill (focusing on its motion) Chemical Energy The energy found within the chemical bonds of molecules Stored in matches Sound Energy Energy created by vibrating particles A song being sung Thermal Energy The kinetic energy of the particles of a substance Heat coming off of a fire Electromagnetic Energy Vibrations of electrically charged particles Visible light Nuclear Energy Energy produced with an atom's nucleus breaks apart Energy produced with the nuclei of 2 atoms join together Atomic bomb Heat Transfer Matching Convection Cycle of hot liquid rising and cooler liquid falling Conduction Heat transfer that occurs when objects are in direct contact Radiation Heat transfer that occurs when objects are not in direct contact How does heat always move between objects? Low temp to high temp High temp to low temp It is constantly moving back and forth From the object with grater mass to the one with less mass Sort each example with the heat transfer that best describes it Conduction Frying an egg in a pan Burning your mouth on hot pizza Rubbing your hands together to keep warm Convection Hot air circulating to the top of the bleachers during a pep assembly Water boiling Cycle that occurs in the Earth's mantle and causes continental drift Radiation Warming your hands over a fire Feeling the warmth of the sun I mix up brownies and the batter has a mass of 412g. Assuming that I use every gram of brownie batter which of the following would be true based on the Law of Conservation of Mass? The cooked brownies would have a mass of 400g, the reaming was destroyed by the heat of the oven The mass of the brownies would be 418g because the oven increases the thermal energy which creates a small amount of mass The brownies would have a mass of 400g while the remaing 12g are lost in the form of heat and water vapor There is no way to know the final mass of the brownies because they were cooked in an oven Write the chemical symbol for the following elements. REMEMBER! Capitalization is important! If you use the wrong capitalization it will be marked wrong.
