Earth's Layers
This is the outermost layer of Earth
What is the crust?
Is earth's interior hot or cold
What is Hot?
What causes seismic waves
What are Earthquakes?
This is the formula for density
What is Mass/Volume?
Can scientists directly see Earth's Core?
What is No?
This is the Earth's thickest layer
What is the Mantle?
What happens to temperature as you move deeper into earth
What is it gets hotter?
Are P or S waves faster
What are P waves?
Is object a or b more dense Object A: 20g in 10 mL Object B: 40g in 10 mL
What is Object B: Density 4g/mL
What is indirect evidence
What is evidence that allows scientists to learn about something without directly observing it?
This layer is a liquid
What is the Outer Core?
Name one source of Earths internal heat
What are Radioactive decay, Primordial Heat, Friction?
This is what P waves stand for
What is Primary?
Calcuate the Density of an object that is 30g in 15mL
What is 2g/mL?
What type of evidence helps scientists learn information from Earthquakes
What are Seismic Waves?
Give me 2 pieces of direct or indirect evidence as to why we think we know what the Earth is made of.
What are S-waves, hotter as you go on, different densities, magnetism?
What is the inner core?
How can heat cause materials inside the earth to move
What is by letting the less dense objects rise and the more dense objects sink?
This type of wave cannot travel through liquids
What are S-waves?
Which is generally more dense Earth's Crust or Earth's Core
What is Earth's core?
What is models allow us to represent unseen or difficult processes?
Put the layers of the earths core in order from outside to inside?
What are Crust, Mantle, Outer core, Inner core?
Why is flowing iron in the inner core important to earth
What is Iron gives us are magnetic field?
Scientist observe that S-waves cannot travel though liquids which layer of the earth would S-waves not go thorugh
What is the Outer core?
Why do the different layers of Earth have different densities
What is they are made of different objects and materials due to gravity?
A student makes a model of Earth as one big ball and decides to change it to have multiple layers what did this student do.
What is revise a model on new information?
