What happens to temperature and pressure as you go deeper inside Earth?
Temperature and pressure both decrease.
Temperature and pressure both increase.
Temperature increases, pressure decreases.

Earth's crust is
a layer of solid rock that includes both dry land and ocean floor.
a layer of molten (hot) rock which flows.
all composed of basalt.
all composed of granite.
Basalt is
dark, fine-grained rock making up continental crust.
light, coarse-grained rock making up oceanic crust.
light, coarse-grained rock making up continental crust.
dark, fine-grained rock making up oceanic crust.
Granite is
dark, fine-grained rock making up continental crust.
light, coarse-grained rock making up continental crust.
light, coarse-grained rock making up oceanic crust.
dark, fine-grained rock making up continental crust.
The mantle is
a layer of very hot solid rock.
a layer of hot, liquid metals (nickel and iron).
a layer of hot, solid metals (nickel and iron).
the outermost layer of solid rock which makes up the continental and oceanic floor.
The uppermost part of the mantle and crust which is strong, hard, rigid rock is called the
asthenosphere
mesosphere
lithosphere
outer core
The very hot, less rigid (soft, bendable) layer of the mantle that the lithosphere floats or lays on is called the
mesosphere
oceanic crust
continental crust
asthenosphere
What layer of Earth's interior is made mostly of metal, lies below the mantle, and is divided into two parts - a liquid and solid?
the core
the crust
the asthenosphere
the lithosphere
Which description best describes Earth's inner core?
a layer of liquid metal - mostly iron and nickel.
a layer of flowing molten rock.
a dense ball of solid metal - mostly iron and nickel.
a dense ball of sold rock at the center of the Earth.
Earth's magnetic field is caused by
movements in the liquid outer core.
movements in the solid outer core.
the metals in Earth's crust.
the movement of the solid, hot rock in the asthenosphere.
