Which term defines weathering?
a) the breaking down of rocks
b) the moving of rocks and sediments from one place to another
c) the forming of new rocks through cementation
d) the forming of rocks from heat and pressure
When a volcano erupts, ash can enter Earth’s atmosphere. Eventually, the ash falls back down to Earth’s surface. Which term describes the falling of volcanic ash to Earth’s surface?
a) deposition
b) erosion
c) subsidence
d) weathering
Over time, repeated cycles of heating and cooling can cause a rock to crack. The rock may then break into smaller pieces. What is this process called?
a) deposition
b) erosion
c) subsidence
d) weathering
Erosion is a process that slowly changes rocks. Which of the following most likely causes pebbles in a stream to erode?
a) flowing water
b) force of gravity
c) movement of ice
d) freezing and thawing
Deforestation occurs when large areas of trees are cut down. Which of the following impacts on the environment would result from deforestation?
a) Increased Erosion
b) Colder Temperatures
c) Excess Ground Moisture
d) Increased Deposition
Slate is a metamorphic rock that forms from shale, which is a sedimentary rock. Which of the following would be needed for slate to form from shale?
a) weathering
b) erosion and deposition
c) melting and solidification
d) heat and pressure
Declan observed a rock that he found at the beach. The rock felt hard and appeared to made of several different layers of materials. What type of rock is Declan observing?
a) metamorphic
b) sedimentary
c) igneous
d) mud rock
When ice freezes and causes rocks the size of the rock can increase. What process is being explained?
a) erosion
b) deposition
c) physical weathering
d) chemical weathering
Granite forms when liquid magma slowly cools within Earth’s crust. If the granite is exposed to intense heat and pressure, it can change to gneiss. Which type of change takes place when granite turns into gneiss?
a) Sedimentary rock changes to igneous rock.
b) Igneous rock changes to metamorphic rock.
c) Metamorphic rock changes to igneous rock.
d) Sedimentary rock changes to metamorphic rock.
Mainly igneous rocks have been found in a specific area on land. Which natural event most likely took place in the area to form the rocks?
a) landslide
b) earthquake
c) flooding river
d) volcanic eruption
Rocks and sediment change their form as they move through the rock cycle. Which change involves melting?
a) lava to rock
b) magma to lava
c) rock to magma
d) rock to sediment
Over a long period of time, igneous rock can change into sedimentary rock. What must happen to igneous rock before it can change into sedimentary rock?
a) It must be broken down into sediment.
b) It must melt and become magma.
c) Its minerals must be dissolved in water.
d) It must be exposed to high pressure and temperature.
How does chemical weathering differ from physical weathering?
a) Human activity causes chemical weathering but does not cause physical weathering.
b) Chemical weathering does not break rocks down into smaller parts, but physical weathering does.
c) Chemical weathering is acid precipitation and pressure, and physical weathering is wind and temperature changes.
d) Chemical weathering happens when the bonds that hold minerals together break; physical weathering happens when physical actio
