in science class, khan is asked to explain the movement of continents and ocean basins. what did he learn that he could use to explain this movement?
both continents and ocean basins move
How are plate boundaries related to earths plates?
boundaries can be anywhere in an ocean basin or a continent
according to the continental drift theory, what separated the continents?
centrifugal force
lakasha is studying the earths plates in marine science. how could she describe the arrangement of crustal plates using what she has learned in marine science?
crustal plates fit closely together with each plate touching all the plates that are next to it
The Red Sea was created by which kind of movement in the plates?
divergent
ocean ridges are formed from vertical uplift caused by what type of plate boundary
divergent
movement along the san andreas fault is known for causing what type of event?
earthquake
nyema is asked to describe how ocean currents impact weather. what example could she use of a weather event that is impacted by the currents?
el niño
Amera is discussing the movement of water molecules. What word describes what high temperatures do to water molecules?
expand
when using the scientific method, a hypothesis is tested by
experimentation and observation
sea levels can rise but cannot become lower. t or f?
false
volcanoes form only on land. t or f?
false
in what instance does a divergent boundary create a ridge instead of a valley or trench?
if there is magma under the plate
how does heat capacity of water impact the ocean?
it keeps the ocean water temperatures reliably the same
what happens once an item breaks through the surface tension of water?
it sinks
what is an example of a geological feature found at a divergent plate boundary?
mid ocean trenches
When two hydrogen atoms combine with an oxygen atom, they form water. what is this combination known as?
molecule
what is an example of topography?
mountain ranges
when a current theory is disproven, what is MOST likely occurred?
new discoveries show they are incorrect
what marine science research triggers the discovery of the spreading and movement of the plates of the ocean?
submarine mapping of the ocean floor
why does alaska experience 80 days of solid daylight in the summer?
that region of the earth is tilted toward the sun during the summer
the coldest water will be found in which part of the ocean?
the deepest regions
jason is comparing the climates of different cities and their location in the world. how would he describe the relationship between a city's temperature and its location?
the lower the latitude, the warmer the temperature
what is the relationship between plate tectonics and seafloor spreading?
the movement of plates in earths crust is the cause of seafloor spreading
why do tropical islands have consistently warm climates?
they are closer to the equator
how can oceanic plates be described?
they are heavier than continental plates
why is it beneficial for scientists to share their conclusions with other scientists?
to build the body of scientific knowledge

true
a water bottle is placed into a freezer. the next day the bottle has cracked. what property of water explains why this would happen?
water molecules expand upon freezing
