The flow of matter in which layer is directly responsible for the movement of plates that make up Earth's crust?
Inner core
Outer core
Mantle
Crust
When matter in Earth's mantle heats, what happens to it?
It moves toward Earth's surface
It sinks toward the core
It remains stationary
It spreads horizontally only
What happens to heated mantle material as it approaches Earth's surface?
It heats further
It cools
It evaporates
It becomes denser
New areas of crust on the surface are created when the upward motion of magma causes plates to:
Collide
Spread apart
Subduct
Transform
Sections of crust are destroyed when plate motion causes two plates to meet, causing one plate to submerge and form a:
Ridge
Trench
Mountain
Plateau
Earth's outer core and inner core both contain iron. However, the iron in the outer core is liquid and the iron in the inner core is solid. Which statement BEST explains this phenomenon?
The inner core experiences more pressure, which causes the iron to be solid even at extremely low temperatures
The inner core experiences less pressure, which causes the iron to be solid even at extremely high temperatures
The inner core experiences more pressure, which causes the iron to be solid even at extremely high temperatures
The inner core experiences less pressure, which causes the iron to be solid even at extremely low temperatures
Which statement BEST explains how Earth's magnetic field is created?
The solid iron in the inner core flows freely, allowing electrons in the metal to flow as well
The liquid iron in the inner core flows freely, allowing electrons in the metal to flow as well
The liquid iron in the outer core flows freely, allowing electrons in the metal to flow as well
The solid iron in the outer core flows freely, allowing electrons in the metal to flow as well
Rock in Earth's mantle moves very slowly in a circular pattern. Which TWO pieces of information would BEST explain this movement? (Select TWO)
Radiation from the Sun transfers thermal energy to Earth's surface
Radioactive decay in Earth's interior releases energy in the form of heat
Hotter rock is less dense than cooler rock
Hotter rock transfers thermal energy to cooler rock
Cooler rock is less dense than hotter rock
Thermal energy is transferred from the outer core towards the crust through the mantle. Which BEST describes how energy moves through the mantle?
Thermal energy heats up the magma by radiation and passes through the mantle as conduction
Thermal energy rises with heated magma from near the core and sinks back down as it cools through convection
Thermal energy moves by conduction from the outer core, through the mantle, and to the crust by direct contact
Thermal energy radiates from the outer core, through the mantle, to the crust
The P-waves from an earthquake reach a seismograph 6 minutes after the earthquake occurs. The S-waves reach the seismograph almost 5 minutes later. What is the approximate distance from the earthquake to the seismograph?
1000 km
2000 km
3000 km
4000 km
