What explains why the northern hemisphere experiences summer when the southern hemisphere experiences winter?
The earth is tilted.

Why is the inner core solid despite the extremely high internal temperatures?
Extremely high pressure
What is high pressure?

What is the difference between heat and temperature?
Heat- Energy that flows from a warmer body to a colder body.
Temperature- Average kinetic energy

A 0.1kg block of aluminum was heated to a temperature of 80C. It was then placed into a 0.5kg of water with an initial temperature of 20C. Describe the heat transfer.
What happens to the temperature of the water and the aluminum block?
Heat transfers from the aluminum block to the water.
The temperature of the water increases.
The temperature of the aluminum block decreases.

An unknown metal with mass 6.05 g is heated to 90.00°C and dropped into 11.0 g of water at 23.00°C. The final temperature of the system is 23.83°C. What is the specific heat of the metal? Assume the specific heat of water is 4.184 J/g°C.
.095 J/gC

A glass of cold water is placed in a sealed room. After an infinite amount of time, what will happen?
Hint: Is this a open, closed, or isolated system?
Isolated system.
The water will warm and the air in the room will cool until it reaches the same temperature

Draw the Space, Inner Core, and the Mantle on your paper.
Explain how heat is transferred between the mantle and the inner core.
Explain how heat is transferred between space and the mantle.
(hint: What are the three types of heat transfer).
Heat transfers from the inner core to the mantle through conduction.
Heat transfers from the mantle to space through radiation.

What is the difference between magma and lava?
magma- below the earth
lava- breaks the earth's surface.

The mantle is a solid, the outer core is a liquid, and the inner core is a solid. How do we know this and why?
Scientists found out that the outer core was liquid due to the formation of S-wave shadow zones or areas where the S-waves are not detected. During an earthquake, the body waves, which consist of the P-wave and the S-wave travel through the layers of the Earth.

1,400 J of energy is applied to an aluminum rod of unknown mass. Its temperature goes from 20C to 45C. What is the mass of the rod?

A ice cube melts~
Talk about energy transfer using the terms systems and surroundings.
Is this physical reaction exothermic or endothermic?
Melting (changing from a solid to a liquid) requires heat to be absorbed by the ice from the surroundings and, therefore, is endothermic.

Describe a subduction zone between an ocean plate and a continental plate.
The ocean plate is denser than a continental plate. The ocean plate sinks further into the mantle than the continental plate.

Read the passage.
As tectonic plates move apart, mantle pressure decreases and magma wells up from Earth's interior. A volcano is then created.
How is the volcano created?
The volcano is formed by divergent boundaries.

Relate convection currents and density.
You may use water or plate tectonics as an example.
Lighter(less dense) rises while heavier (more dense) cool materials sink. This movement creates circulation patterns known as convection currents.
As it moves farther from the heat source, the water cools(becomes denser) and sinks back toward the bottom of the pan. As the cooler water moves toward the heat source, it becomes warmer(becomes less dense) and rises to the surface again. The motion of water in this pan is called a convection current.

Suppose you are camping in the winter. You have 30 g of ice at 0°C that you need to melt and heat up so that you have drinking water at 40°C.
What is the total energy needed to melt that ice? Include units.
Heat of fusion = 334 J/g
C ice = 2.1 J/g°C
C water = 4.18 J/g°C
Heat of Vaporization = 2260 J/g
15036 J

In terms of endothermic and exothermic processes, is melting similar to vaporization or condensation?
Explain.
Melting is an endothermic process.
Vaporization is an endothermic process.
Condensation is an exothermic process.
So, melting is similar to vaporization.

A geologist identifies location A to be a volcano. A student objects! They state that A is too far away from a plate boundary to the volcano.
Do you agree with the student? Why?
The student is wrong!
A volcano can be formed because it can form over a hotspot!
