Minnamurra revision

What is the result of weathering in the geomorphic processes?

• Removal of sediment

• Movement of sediment

• Buildup of sediment

• Breakdown of sediment

What type of waves are associated with large surges?

• Destructive

• Constructive

• Tidal

• Atmospheric

During El Niño, where is warm water pushed to?

• Eastern Pacific Ocean

• Western Pacific Ocean

• Northern Pacific Ocean

• Southern Pacific Ocean

What is the ecological impact of increased runoff due to hard surfaces in the built environment?

• Increased sediment support and stabilization by root systems

• Slower and filtered runoff due to trunks, branches, and root systems

• Increased flow speed leading to erosion

• Decreased flow speed leading to sediment buildup

How does natural vegetation affect hydrological and geomorphic processes?

• It increases runoff and erosion

• It supports and stabilizes riverbank sediment

• It leads to the removal of sediment

• It causes descending warm air

What type of landform is the Minnamurra Sand Spit classified as?

• Erosional

• Depositional

• Volcanic

• Mountainous

Which type of rock is described as strong & resistant to weathering at the site?

• Marine Sand

• Volcanic bedrock

• Boulders & Pebbles

• Stack Island rock

What is the role of destructive waves at the Minnamurra Rivermouth site?

• They deposit sand to form the spit.

• They erode sand from offshore sandbars and transport it north.

• They block destructive waves, dissipating their energy.

• They provide further protection from wave action to Minnamurra Estuary.

How do constructive waves contribute to the formation of Minnamurra Spit?

• By eroding the volcanic bedrock.

• By transporting and depositing sediments.

• By breaking down boulders at the shore's edge.

• By creating offshore sandbars.

What is the effect of the interaction between Stack Island and Minnamurra Headland on destructive waves?

• They increase the energy of destructive waves.

• They have no effect on the waves.

• They dissipate the energy of destructive waves as they break.

• They redirect the waves towards the estuary.
