types of body waves

Starting from the center of the Earth, the four major Earth's internal layers are____

• Crust, Mantle, Inner Core, Outer core

• Mantle, Outer core, Inner core, Crust

• Inner core, Outer core, Mantle, Crust

• Outer core, Mantle, Crust, Inner core

Which of the ff best describes the outer core?

• it permits plate motion

• it helps in maintain magnetic field

• it is the source of earth's heat

• it's a thin, cold, and rigid layer

This is the fastest kind of seismic wave, and, consequently, the first to 'arrive' at a seismic location

It is considered as the portion of the Earth system that includes the Earth's interior, rocks, and minerals, landforms, and the processes that shape them.

the mohorovicic discontinuity, or moho, separates 2 layers of the earth. tell which

• outer core and inner core

• mantle and outer core

• upper mantle and lower mantle

• crust and upper mantle

all the earth's internal layers have the same temperature

• true

• false

deep in earth's interior, most of earth's mantle is molten, liquid magma

• false

• true

the inner and outer core are made of the same substance but have much different mechanical properties.

• true

• false

The outermost layer of the earth's surface
