WED & Rock Cycle

Over time, repeated cycles of heating & cooling can cause rock to crack.  The rock may then break into smaller pieces.  What is this process called?

• deposition
• erosion
• subsidence
• weathering

Which of the following is mainly responsible for transporting the sand?

• gravity
• ice 
• water
• wind

What is a mound of sand that was formed and moves by the action of wind?

• dune
• coastline
• delta
• beach

How does chemical weathering differ from physical weathering?

• Human activity causes chemical weathering but does not cause physical weathering. 
• Chemical weathering does not break rocks down into smaller parts, but physical weathering does.
• Chemical weathering happens when the bonds that hold minerals together break; physical weathering happens when physical actions wear away and crack the rocks.
• Chemical weathering is acid precipitation and pressure, and physical weathering is wind and temperature changes. 

What is the general name for a large mass of ice that slowly moves over land?

• glacier
• pack ice
• iceberg
• sea ice

Lake Eola is a sinkhole lake. Which of the following statements best describes how it formed?

• An underground cave collapsed and the sediment plug opened.
• An underground cave collapsed and became plugged by sediment.
• A cut-off meander of a stream formed a crescent-shaped lake.
• A chunk of ice deposited by a glacier melted, and the glacial drift around the former ice block held the water in place.

What are the two ways that rocks are broken down into smaller pieces?

• abrasion & erosion
• chemical weathering & dissolving
• physical weathering & precipitation
• chemical weathering & physical weathering

What process is need to change metamorphic rock into sedimentary rock? 

• Cooling
• Melting
• Deposition
• Heat

Rocks and sediment change their form as they move through the rock cycle. Which change involves melting?

• lava to rock
• magma to lava
• rock to magma
• rock to sediment

Declan observed a rock that he found at the beach. The rock felt hard, it was yellow, and it appeared to be made of layers. Declan concluded that the rock was sedimentary. Which observation best supports this conclusion?

• the yellow color
• the layers within the rock
• the hardness of the rock
• the location where the rock was found
