Energy In The Rock Cycle
• The rock cycle shows the
possible ways in which
one type of rock can
slowly change to another
type of rock.
• The rock cycle is driven by
different types of energy
that slowly change rock.
• The changes in the rock
cycle usually take
thousands to millions of
years.
Solar Energy
• Solar Energy drives the weather.
• Weather erodes rocks.
• Examples:
– Wind breaks down rocks and moves sediments.
– Rain slowly dissolves rock and moves sediments.
– Ice Wedging - Snow melts and runs into cracks,
freezes, expands, and breaks rock.
– Glaciers scrape rock and carry sediment as they move.
– Natural Disasters
– Heat from the sun causes rock to crack or buckle from
pressure caused by its atoms’ increasing speed.
Gravity
• All objects have gravity.
• Earth’s Gravity pulls all
objects towards the
center of the Earth.
• Gravity helps move
rocks and sediment
from place to place.
• Examples: waterfalls,
rockslides, mudslides,
glaciers
Chemical Energy
• Chemicals dissolved in
water harden sediments
and cement them
together to form new
rocks as water
evaporates or moves
away.
• Chemical reactions
within the earth’s crust
change rocks from one
form to another.
Heat
• Earth was once a molten ball
of rock.
• The earth’s interior still
contains molten rock and
metal.
• Heat in the earth’s interior
causes convection currents in
the mantle that move the
earth’s tectonic plates, causing
earthquakes, mountain
building, and volcanic activity.
• Heat inside the earth causes
rocks to melt partially or
completely.
Radioactive Decay
• Earth’s crust and mantle
contain radioactive
elements that heat
rocks as they decay.
Pressure
• As sediments pile up they
put pressure on lower
sediments and smash
them together to make
rocks.
• When the earth’s tectonic
plates move they push
against each other. The
resulting pressure
changes the crystal
structure and
composition of rocks.
