Question 1

HOW ARE SEDIMENTARY ROCKS FORMED

Answer 1

WHEN ROCKS CRUMBLE THEY FORM SMALL GRAINS

THE GRAINS ARE CARRIED AWAY BY RIVERS OR THE WINDS THIS IS KNOWN AS EROSION

THE GRAINS THEN SETTLE OUT AND FORM LAYERS

THE OTHER LAYERS GET PUT ON TOP OF THEM

COMPACTION TAKES PLACE, THE LOWER LAYERS GET PRESSED TOGETHER

WATER IS SQUEEZED OUT. THE MINERAL CEMENTS THE GRAINS TOGETHER

THEN THE SOLID ROCK FORMS AFTER YEARS AND YEARS
