Plate Boundaries
What is a convergent boundary?
when two plates move towards each other
What is the mitochondria?
powerhouse of the cell
Is there sometimes differences between different organism's cells?
Yes, the differences depend on the cell type.
What is the main tool used to predict weather?
Satellites such as GOES
How does the Earth rotate?
It rotates around the sun on it's axis.
What is a divergent boundary?
when two plates pull away from each other
Do cells keep living on something dead?
Some cells take longer to stop functioning after something dies.
Can different organisms' cells have different sized organelles?
Yes they can, for example the vacuole is much bigger on a plant cell than an animal cell.
What are isobars?
Similar pressure areas that are connected by a line on a weather map.
What are fossils?
the preserved remains of dead organisms (animals, people, plants, insects, etc.)
What is a transform plate boundary?
when two plates slide against each other
What is a nucleus?
it tells the cell its job, and contains the DNA for that
What is a cell wall, and what cell has it?
A cell wall is the protective lining of a cell and helps the cell keeps its shape. A plant cell has it.
What two fronts are there and what do they do?
Cold Front - cold air replaces warm air.
Warm front - warm air replaces cool air.
How does land break down?
weathering and erosion
What forms at a convergent plate boundary?
mountains, volcanoes
What is a chloroplast, and what cell has them?
it gives a green color, turns sunlight into energy, and is found in plant cells.
What is a Jet Stream?
High speed wind in the upper levels of the atmosphere
What is an organism?
any living thing
What is Pangea, and what evidence is there that proves it existed?
Pangea - all of the continents were connected.
The same fossils were found in continents that are not near each other.
The continents could fit together like puzzle pieces.
What is mitosis?
When two cells split apart and create two daughter cells.
Are there cells that do not have a nucleus?
Yes, prokaryotes which are bacteria and arachea. Most are small single celled organisms.
What could cause a thunderstorm, what is created?
A warm front and cold front collide. They create a low pressure area because the winds are traveling in a counter clockwise direction.
What are the two cell types?
Prokaryote and Eukaryote
