Water • a primary agent in sediment production

(weathering), transportation (erosion) and deposition

• is essential for the cementation of sediment into sedimentary rock

What are sediments? Loose rock particles produced by weathering preexisting rocks.

Sediments include boulders, cobbles, pebbles, sand, silt and clay

How do they become sedimentary rock? Sedimentary rock is formed when rock is weathered, eroded (transported), deposited, compacted and cemented.

Transportation or Erosion • The movement of sediment away from its source rock by water, wind and ice

• Flowing water in streams and rivers carry tons of sediment to the oceans each day.

Deposition • Occurs when movement slows and suspended sediments are dropped

• Streams deposit when they slow down. • Glaciers deposit till at the bottom of a

slope or when the glacier begins to melt.

Most of Oregon is in the Pacific Ocean Watershed and much of the drainage in this area is carried to the Pacific through the Columbia River. The westernmost part of the state drains directly into the Pacific through streams such as the Nehalem, Umpqua and Rogue Rivers. Small areas in southeastern Oregon are in the Great Basin, an area of the United States with internal drainage that does not contribute water to an ocean. Saturday, May 22, 2010
