What are the 2 sources of Earth's internal heat energy? select 2
Radioactive decay
Sunlight
Heat of formation (of the Earth)
Moonlight
What caused the Earth to get very hot during its formation?
Radioactive decay under the surface
The heat from the sun
The constant bombardment of meteorites
Heat from Mars
The Earth's internal temperature is in an equilibrium, which means its creating as much heat as it's losing. What process is causing the heat inside the Earth?
Heat of formation is still happening
Radioactive decay is releasing heat inside Earth
Earth is still being bombarded by meteorites
The Sun is the source of Earth's interior heat
Which of Earth's layers are separated based on chemical composition?
Crust, Inner Core, Outer Core, Mantle
Lithosphere, Athenosphere, Mesosphere
Crust, Mantle, Core
Lithosphere, Athenosphere, Mesosphere, Inner Core, Outer Core
Earthquake waves can be used to determine the density of Earth's crust. How does this work?
The earthquake waves are blocked, so it shows the layers are solid.
The earthquake waves are shortened, showing the layers are made of the same material
The earthquake waves are lengthened, showing the mantle is made of water and salt
The earthquake waves travel at different speeds, showing that the layers have different compositions
What does "chemical composition" refer to?
How Earth's layers interact with one another
Chemical reactions that take place in Earth's layers
The kinds of atoms and molecules Earth's layers are made of
The physical properties of Earth's layers
Meteorites often are used to infer the structure of internal Earth? Why?
All materials from space are made only of iron
Traveling through the atmosphere alters the meteorites
Meteorites and the Earth were both formed at the same time from the same nebula
Meteorites were once part of Earth
What does the phrase "physical properties" refer to?
How Earth's layers interact with one another
Chemical reactions that take place in Earth's layers
The kinds of atoms and molecules that make up Earth's layers
The chemical composition of Earth's layers
The lithosphere floats on top of the asthenoshpere, how are the two layers separated?
The layers have different chemical properties
The layers have different physical properties
The lithosphere has a higher density than the Asthenosphere
The asthenosphere is made of different materials than the lithosphere
What indirect evidence is used to assume that the outer core is liquid?
Dense rock samples from drill holes from the crust
Lightweight crustal rock are first made in the outer core
Heat from volcanic lava
Seismic waves decrease in speed when they reach the outer core
What process causes movement of earths tectonic plates?
The spinning of Earth gives the plates energy to move the continents
They move when he creates convection currents in the earths mantle
They are floating in the ocean and move randomly
They move when volcanoes erupt and earthquake faults slip
Which process the best explains how heat moves inside the earth?
Heat from the asthenosphere sinks to the outer core
Heat from the lithosphere sinks to the asthenosphere
Heat from the outer core rises through the mesosphere
Heat from the mesosphere is distributed evenly throughout Earth
The picture below shows a hot rear object like a heater creating warm air in the room what process is being illustrated by the arrows in the picture?
Redshift
A convection current
Plate tectonics
A conduction current
Exam in the picture above what would cause the warm air to move in the same direction but more quickly?
Turning off the hot radiator
Adding a hot radiator under the window
Increasing the air coming out of the radiator
Increasing the temperature outside the window
