Convection and the mantle / volcanes plates

Heat

constantly being transferred around the earth and earth’s surfacefaste

Yeshhe

Do faster moving particles have more energy?

heat transfer

the movement of a heat from a warmer object to a cooler object

RADIATION, CONVECTION, CONDUCTION

HOW IS HEAT BEING TRANSFERRED?

radiation

the transfer of energy that is carried in rays

convection

heat transferred by movement of fluid

conduction

heat transferred by materials that are touching

density

a measure of how much mass there is in a given volume or substance

convection current

the flow that transfers heat within a substance

CONVECTION OCCURS IN EARTH’S MANTLE

HEATING AND COOLING OF A FLUID, CHANGES IN THE FLUID’S DENSITY, AND THE FORCE OF GRAVITY COMBINE TO SET CONVECTION CURRENTS IN MOTION

volcano

a mountain that forms in Earth’s crust when molten material, or magma, reaches the surface

magma

a molten mixture of rock-forming substances, gasses, and water from the mantle (can form solid rock)

lava

magma that has reached the surface (can form solid rock)

WHERE VOLCANOES ARE FOUND ON EARTH’S SURFACE

VOLCANIC BELTS FORM ALONG THE BOUNDARIES OF EARTH’S PLATES; ABOVE A HOT SPOT WHEN MAGMA ERUPTS AND REACHES THE EARTH’S SURFACE

ring of fire

one major belt of volcanoes

island arch

a sting of islands created by resulting volcanoes

hot spot

an area where material from deep within Earth’s mantle rises through the crust and rises to form magma

millions of years

how long do hot spots stay in place
