​ (a)   processes add new land to the surface of the Earth. Examples of constructive processes include​ (b)   due to hot spot volcanoes bringing ​ (c)   to the surface. Other examples include sediment deposition at the mouth of a river, landslides, and mountain formation due to converging ​ (d)   plates.

Weathering and erosion are both natural processes that shape the Earth's surface, but they differ in how they break down and move rock and sediment

• Weathering creates new materials; erosion destroys them.
• Weathering and erosion are the same process.
• Weathering moves materials; erosion breaks them down.
• Weathering breaks down materials; erosion moves them.

There are two types of weathering:

• Physical erosion and biological weathering
• Thermal weathering and electrical weathering
• Frost weathering and gravitational weathering
• Mechanical weathering and chemical weathering

In _____weathering, a force acts directly. Water and wind can move over rocks carrying small, abrasive particles that slowly wear the rock down. Physical

• thermal
• mechanical

• biological
• chemical

In ____ weathering, a chemical interaction occurs. For example, some rainwater contains dissolved compounds that make it acidic.

• chemical
• mechanical
• biological
• physical

What geological forces might be responsible for this range of mountains?

• erosion of the land by the ocean

• (converging) tectonic plate movement

• 
  deposition of the sediments by the ocean

• weathering of a river
