What are the examples of deposition in the passage: Helen is visiting Blowing Rock Preserve in Jupiter, Florida. She walks along the beach, enjoying the view. She sees water shooting up into the air through a hole in the rocks. She notices that the water breaks the rocks apart. As she walks down the beach, she sees many large sand dunes with seagrass growing on them. As the tide goes out, Helen sees a sandbar that has formed offshore. She dips her feet into the water and notices that the waves are carrying small shells and bits of rock away.

• large sand dunes with seagrass growing on them, a sandbar that has formed offshore.

• water shooting up into the air through a hole in the rocks, rocks breaking apart.

• waves carrying small shells and bits of rock away, water breaking rocks apart.

• Helen walking along the beach, enjoying the view.

More sinkholes form each year in Florida than in any other state. Which of these explains why more sinkholes occur so often in Florida?

• because of the beaches

• because of the low elevations

• because of the high temperatures

• because of the soft rock underground

Match the descriptions with the correct type of weathering that lead to the formation of sinkholes.

Limestone rock breaks into smaller pieces.

Limestone rock is dissolved by water underground.

Pressure changes on the surface cause the ground to collapse.

Calcium carbonate rock sits in water and forms bubbles.

Groups:

(a) Mechanical Weathering

,

(b) Chemical Weathering

• soft limestone rock is dissolved by water underground

• when calcium carbonate rock sits in the water, it forms bubbles

• pressure changes on the surface cause the ground to collapse

• limestone rock breaks into smaller pieces

What does each item represent? Write the material from the model next to the part of sinkhole it represents.

• sugar cubes

• Harder rock that does not dissolve

• weight

• Soft rock

• clay

• A car or building
