• sediment

• weathering

• erosion

• constructive process

This type of weathering breaks rock into smaller pieces but does not change the rock chemically (2 answer choices)

• erosion weathering

• mechanical

• physical

• constructive

These are loose particles of weathered rock such as pebbles or sand.

• sediment

• glacier

• sea stack

• delta

Over time, repeated freezing and thawing of water in a rock may split it apart. Scientists call this

• abrasion

• ring of fire

• desert pavement

• ice wedging

NGSS.MS-ESS2-2

This type of weathering changes rock into one or more new substances that are usually weaker than the original rock.

• ice wedging

• sediment weathering

• chemical weathering

• glacier weathering

One example of chemical weathering is

• ice freezing inside rocks

• glaciers moving soil

• oxygen combining with iron to form rust

• landslides

The main agent of erosion is

• water

• wind

• landforms

• animals
