Science Finals study guide packet 2 - 6th grade - 2015
| Term | Definition |
|---|---|
| Glacier | A large mass of moving ice and snow on land- it can cover continents- formed from thousands of years of accumuqlted snowfall |
| Ice Age | Period of time on earth that has low temperatures |
| Sea Level | The elevation of the ocean- Zero in elevation |
| Wisconsin Glacier | A glacier that moved slowly south- anything in its path was picked up and tumbled around as the glacier acted like a gigantic snowplow |
| Landform | A feature of topography formed by the processes that shape earth,s surface |
| Sediments | Earth's materials deposited by erosion- makes up the earth's surface |
| Erosion | The process by which water, ice, or gravity moves weathered rock and soil- the taking away of sediments |
| Glacial Debris | Sediments from mountains, lakes, rivers, and valleys all were trapped under the ice- Glacial debris is the sediments that become part of the glacier itself and move with the glacier |
| Harbor Hill Advance | One advance that contributed the most to what Long Island looks like today ( in harbor hill) - it occured 17,000 years ago |
| Ronkonkoma Advance | Another advance that contributed the most to what Long Island looks like today (in Ronkonkoma)- it occured 60,000 years ago |
| Deposition | The process in which sediment is laid down in a new location |
| Moraine | A ridge formed by the till deposit at the edge of a glacier |
| Out wash Plain | The lighter particles that were washed off and formed a plain to the south of the ice edge |
| Bluffs | Large things that drop to the sound show layering sediments that were once contained in the ice of the glacier and now show us a cut way view of the moraine |
| Harbor Hill Moraine | A moraine in Harbor Hill |
| Harbors | indents in shore lines |
| Kettle Holes | Large depressions in the ground |
| Kettle Lakes | If the kettle holes were so deep that they came in contact with the water table they would fill with the water- these kinds of lakes are known as kettle lakes |
| What do we call the elevation of the ocean's surface? | Sea Level |
| What is the flat sandy area found downhill from the moraine? | Out wash plain |
| What is the name of the outwash plain found south of the Ronkonkoma Moraine? | The South Shore Outwash plain |
| What is an area of permeable sediment that contains water? | Aquifer |
| What is the name of the outwash plain found south of the Harbor Hill Moraine? | The Terryville Outwash plain |
| What do we call a kettle hole that comes in contact with an aquifer and fills with water? | Kettle Lake |
| What do we call materials that make up the earth's surface? | Sediments |
| What do we call the advance of the glacier that occured 17,000 years ago? | Harbor Hill Advance |
| What do we call the advance of the glacier that occured 60,000 years ago? | Ronkonkoma Advance |
| BP means what? | Before Present |
| What moraine was left 60,000 years ago? | The Ronkonkoma Moraine |
| What is the name of the glacier that made Long Island? | Wisconsin Glacier |
| What is the name of the glacier that occured 60,000 years ago? | The Ronkonkoma Advance of the Wisconsin Glacier |
| What is the name of the glacier that occured 17,000 years ago? | The Harbor Hill Advance of the Wisconsin Glacier |
| What is th name of the impermeable sediment found at the bottom of Long Island's aquifer? | Clay |
| The taking away of sediments is called what? | Erosion |
| What is made from large ice fingers digging into a moraine, and then filling with sea water? | Harbors |
| What is a steep hill formed from the erosion of a headland or moraine by the sea? | A Bluff |
| Kinetic Energy | The energy an object has due to it's motion |
| Potential Energy | Energy that is stored and available to be used later |
| Load | The amount of sediment that a river or stream carries |
| Slope | A slant going downhill on a landform |
| Abrasion | The grinding away of rock by other rock particles carried in water, ice or wind |
| Turbulence | A type of movement of water in which, rather than moving downstream, the water moves every which way |
| Friction | The force that opposes the motion of one surface as it moves across another |
| Streambed | The bottom of a stream or river |
| Banks | A landslide sloping down alongside a river or stream |
| Mixture | A material made of two or. ore substances that are not chemically boned together |
| Substance | Anything that contains only one pure type of material |
| Elements | A substance that cannot be broken down into simpler substances- the building blocks of matter(there are 118 of these) |
| Homogeneous Mixture | A mixture where the substances are distributed evenly throughout the mixture |
| Heterogeneous Mixture | A mixture where the substances are unevenly distributed throughout the mixture |
| Meter | The SI unit that measures the distance between two points |
| Volume | The amount of space an object occupies |
| Physical Property | Any characteristic of a material that can be observed, measured |
| Density | The amount of mass an object has compared to its volume |
| SI Units | The system of International Standard metric measurements |
| Volume | The space a substance occupies |
| Mass | The amount of matter in an object |
| Weight | The force an object exerts because of gravity |
| Compound | When two or more different atoms chemically combine to form a new substance |
| Molecule | When two or more atoms combine to form a new substance |
| Atom | The basic particle that makes up an element |
| Chemistry | The study of matter |
| Water | is a substance |
| Milk | is a homogeneous mixture |
| Oatmeal | is a heterogeneous mixture |
| Grams | The SI Unit that measures mass |
| Liters | The SI Unit that measures volume |
| A fire usually indicates what type of change? | Chemical |
| What type of change is freezing? | Physical |
| What type of change is melting wax? | Physical |
| What type of change is bending a paper clip? | Physical |
| What type of change is electrolysis? | Chemical |
