The Blue Planet
This is the percentage of Earth's water that is actually freshwater.
What is 3%?
This is the scientific definition of a fluid's resistance to flow.
What is viscosity?
This force is primarily responsible for the daily rising and falling of ocean tides.
What is the Moon’s gravity?
This is the formula used to calculate density.
What is Mass divided by Volume (D = m/V)?
This term describes the area of land where all water drains into a single river or lake.
What is a drainage basin (or watershed)?
According to the Particle Theory of Matter, the particles in this state are close together but can slide past each other.
What is a liquid?
These are the "smallest" tidal movements, occurring when the Sun and Moon are at right angles to each other.
What are Neap Tides?
Ocean water is more dense than freshwater because of this factor.
What is higher salinity (salt content)?
This process in the water cycle involves liquid water turning into water vapor, leaving salt behind in the ocean.
What is evaporation?
If a 100 mL sample of syrup takes 25 seconds to flow through a funnel, this is its calculated flow rate.
What is 4.0 mL/s?
These two factors are most responsible for creating surface ocean currents.
What are wind and Earth’s rotation?
If a block of wood has a mass of 20g and a volume of 40cm³, this is its density.
What is 0.5 g/cm³?
This specific part of the ocean floor is what you encounter immediately after walking off the continental shelf.
What is the continental slope?
Increasing the concentration of a substance (like adding more pigment to paint) increases viscosity because it creates more of this between particles.
What is friction?
This type of tide occurs when the Sun, Moon, and Earth are in a straight line, pulling the water higher than usual.
What is a Spring Tide?
Using the displacement method, if a bolt is added to 30 mL of water and the level rises to 40 mL, this is the volume of the bolt.
What is 10 mL?
Coastal areas like St. John’s have milder winters because water has this property, meaning it heats and cools very slowly.
What is high heat capacity?
When you heat a liquid like honey, this happens to its viscosity.
What is it decreases (or gets thinner)?
This event brings cold, nutrient-rich water to the surface, often increasing local fish populations.
What is upwelling?
Based on Particle Theory, this is why a rock is usually denser than air.
What is because particles in solids are closer together (more mass in the same volume)?
If global temperatures continue to rise and cause glaciers to melt, name two specific negative results for coastal communities.
What are rising sea levels and increased coastal erosion?
