structure of the earth

Evidence gathered by geologists from drilling rock samples is known as

• indirect evidence

• direct evidence

• concrete evidence

• theoretical evidence

The earth is divided into four layers

• crust, magma, mantle, core

• crust, mantle, magma, core

• inner core, outer core, crust, lithosphere

• crust, mantle, outer core, inner core

the outer core is composed of

• melted iron and nickel

• iron and nickel

• magma and nickel

• magma and iron

The inner core is the

• coldest layer of the earth

• hardest layer of the earth

• melted layer of the earth

• hottest layer of the earth

The inner core is

• solid

• liquid

• melted

• rocky

The outer core is composed of liquid iron and nickel

• True

• False

Thickest layer of the earth is the

• crust

• core

• mantle

• outer shell

There are two types of crust

• oceanic crust and continental crust

• asthenosphere and lithosphere

• basalt and granite

• nickel and iron

Oceanic crust is composed of

• basalt

• granite

• igneous rock

• sedimentary rock

Continental crust is composed of

• basalt

• granite

• sedimentary rock

• igneous rock
