Week 2 Enviro Change and Management

What are the two types of waves in Geography?

• Big and small

• Point breaks and reef breaks

• Constructive and destructive

• Continual and destructive

Destructive waves have...

• A strong backwash
• A strong swash
• A strange name

What is key in the creation of sand dunes? (Select 2)

• Onshore Winds to transport sand up the beach

• Constructive waves

• Off-Shore Winds to transport sand up the beach

• High Energy wave environment

How does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place.
• makes the rocks last longer.
• expands cracks and breaks rocks.
• causes rocks to fall in landslides.

Coastlines are mostly different because of:

• Gravity

• Wave action

• Magnetic fields

• Entropy

This rock clearly shows the strength of which process?

• physical weathering

• attrition

• biological weathering

• chemical weathering

These are called _______________________.

• slumps
• mudflows
• creeps
• landslides

These gravestones have slowly broken down and turned a blackish color due to the action of:

• ice wedging
• abrasion
• acid rain
• mechanical weathering

When wind, water, or ice leave materials in a location, this is known as:

• Weathering
• Erosion
• Deposition
• Transportation

How do plants weather rocks?

• during photosynthesis
• when roots grow into cracks of rocks and expand the rock
• when the plant moves water from the roots to the leaves
• Plants don't weather rocks
