BHS Rocks to Soils Homework 1

Types of rocks: What are the three main types of rocks?

• Igneous, sedimentary, and metamorphic

• Volcanic, sedimented, and metamorphosed

• Granite, limestone, and marble

• Hard, soft, and medium

Types of rocks: How are igneous rocks formed?

• From the compression of organic materials

• From the cooling of ocean water

• From the evaporation of water

• From the solidification of molten rock material

Types of rocks: What are the characteristics of sedimentary rocks?

• Formed millions of years ago

• Formed from volcanic activity

• Formed from laying down of material from rivers and into the sea. Over time this is pressed downwards with the weight of the water forms layered rock.

• Usually dug out of the Earth's mantle

Types of rocks: How are metamorphic rocks formed?

• Through the process of heat and pressure acting on existing rocks

• Through the process of volcanic activity

• Through the process of chemical weathering

• Through the process of erosion and sedimentation

Types of rocks: Give an example of each type of rock.

• Igneous - Slate, Sedimentary - Shale, Metamorphic - Pumice

• Igneous - Granite, Sedimentary - Sandstone, Metamorphic - Marble

• Igneous - Obsidian, Sedimentary - Gneiss, Metamorphic - Chalk

• Igneous - Limestone, Sedimentary - Basalt, Metamorphic - Quartz

Rock cycle: What is the rock cycle?

• The rock cycle is a type of exercise routine involving lifting heavy rocks

• The rock cycle is a popular rock band from the 1980s

• The rock cycle is a method of cooking using only rocks

• The rock cycle is a continuous process of rock formation, transformation, and breakdown.

Rock cycle: Explain the processes involved in the rock cycle.

• Weathering, erosion, deposition, compaction, cementation, melting, crystallization, and metamorphism

• Evaporation, condensation, precipitation

• Sublimation, deposition, subduction

• Photosynthesis, respiration, fermentation

Rock cycle: How do sedimentary rocks transform into metamorphic rocks?

• Through the process of chemical weathering and dissolution.

• By the process of cooling and solidification.

• Through the process of erosion and weathering.

• Through the process of heat and pressure.

Rock cycle: What role do heat and pressure play in the rock cycle?

• They transform existing rocks into new types of rocks

• They cause rocks to disappear completely

• They turn rocks into liquid

• They have no effect on the rock cycle

Rock cycle: Describe the role of erosion and weathering in the rock cycle.

• Erosion and weathering turn rocks into liquid.

• Erosion and weathering have no impact on the rock cycle.

• Erosion and weathering break down rocks into smaller pieces, which then become sediment.

• Erosion and weathering create new rocks from scratch.
