WEATHER ING AND EROSION …Forces changing our Earth

OUR WORLD IS CONSTANTLY CHANGING…  Mountains crack and rocks fall down the slopes…  Rivers get bigger and faster…  Sand dunes grow and move across the deserts…  Caves are growing bigger…  Canyons are getting wider…

IT’S HAPPENING EVERYDAY, ALL DAY LONG

WATER FREEZING IN ROCKS CAUSES WEATHERING

ROCKS BUMPING AGAINST EACH OTHER IN RIVERS IS WEATHERING

PLANTS GROW BETWEEN ROCKS AND BREAK THEM APART

EROSION

THE GRAND CANYON WAS FORMED BY THE RUNNING WATERS OF THE COLORADO RIVER

THE WIND CAN CARRY SANDS AND ROCKS AWAY AND CARVE BEAUTIFUL FORMATIONS

LANDSLIDES AND ROCK SLIDES ARE EROSION…

WEATHERING AND EROSION CAN WORK TOGETHER……..

NOW, LET’S TAKE A QUIZ

A RIVER GETS WIDER AS THE SIDES ARE WASHED AWAY

WAVES POUND THE ROCKS AND BREAK THEM

DESERT WINDS BLOW THE LIMESTONE AWAY TO MAKE SWIRLS IN THE LAND
