How do CLASTIC sedimentary rocks form?

*CLASTIC SEDIMENTARY ROCKS: ____________________________

_______________________________________________________

Compaction and Cementation: Over millions of years fragments

become compacted (squeezed tightly together), which causes some of

the minerals in the rock to dissolve. The dissolved minerals fill the

spaces between sediment particles and act like cement, gluing the

sediments together.

What determines one clastic rock from another?

NOTICE THE LAYERS. SEDIMENTARY ROCKS CAN OFTEN HAVE LAYERS,

BECAUSE THE ROCK PARTICLES SETTLE IN LAYERS AFTER BEING

CARRIED BY WATER.

Sum it up

The rock is classified as sedimentary if one or more of

the following characteristics are evident:

(1) layers of sediments (this suggests the process of

compaction)

~ these layers are also called beds or strata and are

often seen in shale or sandstone

7

L.O:SWBAT explain what are sedimentary rocks.

(2) fragmented particles or visible sediments (sand,

pebbles)

(3) fossils or shell fragments (this suggests biological

formation)

Where are sedimentary rocks found?

Sedimentary rocks form in water, so they can easily be found near any body of water.

They can also found in a thin veneer (layer) covering large areas of Earth’s surface.

The environment in which a sedimentary rock forms is often inferred from characteristics of the rocks composition, structure, and texture.

L.O:SWBAT explain what are sedimentary rocks.

Composition The presence of marine fossils indicate the rock formed at or near Earth’s surface from materials deposited in a large body of water.• Larger Particles indicate sediments deposited in shallow water near the

shore.

• Smaller particles indicate sediments deposited in deep water.

Structure

• Ripple marks, cross bedding, and fossil shells indicate that rocks formed from sediments deposited in a shallow sea.

Texture * This has nothing to do with how The rock feels*

• Angular and rough indicate sediments were transported by water for a short period of time.

• Round and smooth indicate sediments were transported by water over a long period of time.
