Layers of the Earth
What are the two types of crust?
Oceanic Crust
Continental Crust
What are the two variables we need to calculate the density?
Mass and Volume
Name the 3 Types of Heat Transfer
Conduction
Convection
Radiation
Name 3 TYPES OF ROCKS
IGNEOUS
SEDIMENTARY
METAMORPHIC
Which of the Earth's Layers (Crust, Mantle, Outer Core, and Inner Core) is the most dense?
BONUS!!!
WHICH OF THE Earth's Layer is the hottest?
Inner Core
If we have the density & the volume of the object, using the equation for density, what is the 3rd piece of information we can find?
(HINT: D = M / V), WHAT DOES M stand for?
Mass
When your feet TOUCHES the sand on the beach, what kind of heat transfer is occurring?
Conduction
Imagine a rock starts out as metamorphic. It then comes into contact with a molten lava, then becomes released into the ocean floor & crystallized over time. What type of rock did it transform into?
Igneous Rock
Earth is composed of many metallic elements. Which layer of Earth contains the greatest amounts of dense, solid iron and nickel?
(Crust, Mantle, Outer Core, Inner Core)
Inner Core
We have two different liquids (oil and vinegar) that are separated and create different layers after time. Explain why they are layers of oil and vinegar and not a mix!
(HINT: Think about the Liquid Layers lab we did earlier - they all have different what??)
In the mantle, the _________ currents bring heat from the outer core to the crust, where ________ occurs to transfer heat. Fill in the blanks!
convection
conduction
What is the name of the process / transition when a rock breaks down & moves from one place to another?
Weathering & Erosion
** BONUS POINTS IF DEPOSITION MENTIONED
Which of the Earth's layers is liquid and responsible for the magnetic fields within the Earth?
(Crust, Mantle, Outer Core, Inner Core)
Outer Core
If a ping pong ball and a golf ball have same volume, but golf ball has more mass than a ping pong ball, what can you tell me about their density?
Golf ball has MORE DENSITY than a ping pong ball
Convection is thought to be one way in which heat is transferred within and between the layers below Earth's surface. Which of the following BEST describes convection?
A. Molecules collide with one another, transferring energy as heat.
B. The hot rock material flows upward in a cyclical motion, cools, and sinks.
C. Electromagnetic waves from the magma reach the surrounding rock.
D. Differences in the chemical composition of the magma causes movement.
B. The hot rock material flows upward in a cyclical motion, cools, and sinks.
THE ROCK CYCLE is a MODEL of the rock's transition. Why is the Rock Cycle a MODEL, not a law?
A Model gives us the CONCEPT / GENERAL IDEA of the cycle, and it is not 100% perfect.
We talked about 3 Layers of the Mantle:
Lithosphere, Asthenosphere, and Mesosphere. However, Lithosphere also includes mantle and another layer of the earth. Which of the Earth's layers is also a part of the lithosphere?
(Crust, Outer Core, and Inner Core)
Crust
There are two ways to calculate the volume:
1) For a REGULAR OBJECT, Volume = l x w x h.
How do you calculate the volume of an IRREGULAR OBJECT?
** WE NEED TO USE A SPECIFIC SCIENCE TOOL!
DIFFERENCE IN A GRADUATED CYLINDER
Explain how the convection currents in the mantle work to move the heat
** NEED TO EXPLAIN WHERE THE HEAT COMES FROM & WHERE THE HEAT IS DROPPED OFF
CONVECTION CURRENT PICKS UP HEAT FROM THE OUTER CORE.
CONVECTION CURRENT RELEASES HEAT TO THE CRUST (BONUS POINT IF CONDUCTION MENTIONED)
There are 2 Types of Changes in the Rock Cycle - what determines the changes?
** BONUS POINTS IF YOU CAN MENTION THE CHANGES
ABOVE SURFACE - WEATHERING / EROSION / DEPOSITION
BELOW SURFACE - VOLCANO / MOUNTAIN and TECTONIC PLATES
