Thermal Energy
3 Ways Thermal Energy can be transferred?
Conduction, Convection and Radiation.
Law of Conservation:
Energy can never be created nor destroyed only transferred from one form to another.
Which of the following elements in Earth's atmosphere is represented by 78%
Nitrogen
What are the four layers of earth?
Mantle
Crust
inner core and outter core
What are the 3 main types of rocks?
Metamorphic, Igneous, and Sedimentary.
Explain how they can be transferred. Conduction, Convection and Radiation.
Through touch
Circular motion/current
Through space
An ice cube is placed onto a hot pan that is sitting on the counter top how will thermal energy move.
The heat will travel from the pan to the ice cube
What is the outer most layer of the atmosphere?
Exosphere
Which statement lists the layers in the correct order from the center of Earth to the outermost layer of Earth?
Inner Core, Outer Core, Mantle, Crust
Long periods of extreme heat and pressure result in the formation of
Metamorphic Rock
What is an example of thermal energy transfer by radiation?
The Sun heating the surface of the Earth
A bottle of water at a room temperature of 21.0 C is placed into a refrigerator with an air temperature of 4.5 C. The thermal energy will move —
From the water to the air until the temperature is equal in both.
Organisms are made of elements that form living matter. Which elements comprise the largest portion of living matter?
Hydrogen, carbon, oxygen, and nitrogen
The Earth is made of many layers. Which layer is made up of part crust and part mantle material?
Lithosphere
Tell me the difference between the 3 types of rocks.
Sedimentary formed by accumulation, compaction, and cementation of sediment.
Metamorphic- put under intense pressure in the earths crust.
Igneous- formed and crystallized through melting and cooling rock.
A student is drinking a cup of hot chocolate as they sit by a campfire on a chilly evening. They know that the cup of hot chocolate transfers thermal energy to the surrounding air. The heated air over their cup of hot chocolate expands and rises and is replaced by cooler, denser air.
This method of energy transfer is —
convection
Your teacher has asked you to make a model of the interior of the Earth. In your model, how do the thicknesses of the lithosphere and crust compare.
The lithosphere is thicker than the crust
When magma is forced between rocks in the Earth’s crust and it cools and crystalizes deep underground, Granite is formed. Granite contains large, visible crystals because the magma cooled slowly. Granite is often used in kitchen countertops, monuments, and buildings. The Texas State Capitol was constructed from red granite from Granite Mountain near Marble Falls, Texas.
Granite is classified as
igneous rock
Give me a example of all three ways you can have conduction, convection and radiation in one place.
Fire- Radiation
Boiling water- convection
Handle- Conduction
What is the Earth's core made of?
Iron/Nickel
Which process best describes the formation of a sedimentary rock?
Solid rock is weathered, deposited, compacted, and cemented.
