What is less than the density of the Mantle?
A fine piece of wire is lowered into some water and then raised back out. Only at one point does the shape of the wire change noticeably. Name that point.
What is the surface?
A crab crawls onto a bathroom scale at the bottom of the Bering Sea. Compared to what the scale would read at the surface, it reads this.

Whether a dictionary is lying flat on a surface or standing on its side, this will remain the same, while another characteristic will change. Name these to respective values.
What are weight and pressure?
when a boat sails from salt water into fresh water, the depth of the boat in the water will change in this way.
What is float lower in the water?
An iceberg has an aircraft that crash landed resting on it. As it gradually travels south, the iceberg melts completely away. The surface of the ocean does this.
What is falls slightly?
Heat will cause the surface tension of a liquid to do this.
What is decrease?
If you were designing a hydraulic lift, there would need to be a piston with a larger area and one with a smaller area. In order to multiply force, you would apply it to this piston.
What is the one with the smaller area?
When standing what part of your body has the greatest blood pressure?
What are your feet?
A 54 Newton block of lead and a 54 Newton block of gold are submerged in a pond. The buoyant force on this one is greater.
What is the lead?
A battleship weighs 50,000 tons. The volume of water it displaces will be this.
What is the volume of 50,000 tons of water?
The direct cause of surface tension is this.
What is the cohesive forces between molecules in a liquid?
A 50 kg one-legged man, and a 50 kg man with two legs both stand on a scale one after another. Their weight according to the scale compares in this way.
What is the same?
If you were to drill holes in a water tower, the water would spurt out the fastest here.
What is the bottom of the tower?
An ice cube is floating in some water. If the part of the cube above water is removed, this will happen to the buoyant force on the ice cube.
What is it will become less?
Greg fills his cup halfway with ice and then fills it to the brim with water. The ice floats to the top and begins to melt. The water level in the cup does this.
What is stays the same?
Pressure in a liquid depends on these two properties.
What are density of the liquid and depth?
The mass of half a liter is this many grams.
What is 500?
A pascal is a derived unit equal to this.
What is one Newton per square meter?
All submerged objects have a buoyant force acting on them that pushes them upward because of this.
What is that the pressure on the bottom of a submerged object is always greater than the pressure on the top.
Ralph went swimming in Lake Michigan and in the Dead sea. He noticed that he floated higher and felt lighter in the Dead Sea. He experienced a greater buoyant force in this body of water.
What is neither?
Adhesion is the attraction of molecules of one substance to molecules of a different substance. Cohesion is the attraction of molecules of a substance to molecules of the same substance. Name which is responsible for surface tension and which for capillarity respectively.
What is cohesion for surface tension and adhesion for capillarity?
A one cubic meter block of balsa wood and a one cubic meter block of granite are thrown in a pond. This one has the greater buoyant force.
What is the granite?
