Independent or Manipulative variable
Two plates grind past eachother
Transform boundary
property of water that causes water to pool up into a water droplet on your windshield?
cohesion
This process also known as ___ brings colder, deep nutrient-dense ocean water to the surface.
upwelling
The very top of a wave is called this___ and the very bottom of a wave is this ____
Crest, trough
Air, water, and sunlight are this factor __ and trees and plants and animals are this factor ____
Abiotic, biotic
The sun is the starting point of energy for all marine food webs EXCEPT for this process, where energy comes from elsewhere
Chemosythesis
This anatomical part of the algae helps the blades and other parts float to the surface of the ocean to photosynthesize
What is the pneumatocyst?
As you go deeper in the ocean ___increases and ____decreases
salinity, temperature
The type of tide that occurs when the tide is coming in
flooding tide
In this food chain, if snakes were to be eliminated, the populations of grasshoppers would ____ and the population of grass would ____
Sun → grass → grasshopper → mouse → snake
decrease, increase
When a fluid (like liquid or gas) is heated unevenly, causing the warmer, less dense parts to rise while the cooler, denser parts sink, creating a continuous circulation pattern that transfers heat from one area to another
Convection currents
The formal name for seaweed
Macroalgae
This determines the three main types of climate zones
Latitude
The name of large masses of moving air caused by uneven heating of the Earth
Global winds
An 'educated guess' based on observations and prior knowledge, that can be tested for
Hypothesis
Photosynthesis adds this to the air and water as a byproduct
O2 oxygen
Seaweeds are classified by this
pigment or color
The source of energy that drives Earth's winds
the sun
Because convection cells are in place in the atmosphere, and Earth is spinning (rotation) on its axis, global winds appear to curve to the right or clockwise in the Northern Hemisphere and the left or counterclockwise in the Southern Hemisphere. This phenomenon is known as the ______ _____
Coriolis effect
Why should you always repeat an experiment?
To ensure similar/accurate results
How to algae get their food?
through photosynthesis
The property of water is responsible for coastal areas having a mild climate?
high specific heat
Earth's global winds are essentially driven by this, which is driven by the unequal heating of the Earth's surface by the sun
convection currents
When the overall tidal bulge is really small, resulting in a minimal difference between high and low tides. occurs during first quarter and last quarter moons
Neap tide
