• deposition

• weathering

• compaction

A meandering stream deposits most of its sediments on the

• inside of meanders where the stream flows faster

• inside of meanders where the stream flows slower

• outside of meanders where the stream flows faster

• outside of meanders where the stream flows slower

As a quartz pebble is transported by a stream, the pebble will become more rounded as a result of

• dissolving as water is running over the rock

• abrasion by colliding with other rocks

• deposition in well-sorted layers

• resistance to weathering and erosion

Sandstone, limestone, and conglomerate cobbles are found in a streambed in New York State where the surrounding bedrock is composed of shales and siltstones. The most likely explanation for the presence of these cobbles is that they were

• weathered from the surrounding bedrock

• formed when shale and siltstone bedrock were eroded

• transported to this area from another region

• metamorphosed from shale and siltstone
