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 |

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 |
