Total questions: 10
Worksheet time: 5mins
How are igneous rocks formed?
Through the solidification and cooling of magma or lava.
Through the compression of organic matter
Through the evaporation of water
Through the erosion of sedimentary rocks
Name two types of sedimentary rocks.
Granite
Shale
Marble
Sandstone, Limestone
What are the main characteristics of metamorphic rocks?
Metamorphic rocks do not contain any minerals
Metamorphic rocks are formed from volcanic eruptions
Formed through alteration of pre-existing rocks, exhibit foliation, contain minerals like mica, quartz, and feldspar.
Metamorphic rocks are always smooth and rounded
What is the process by which sedimentary rocks are formed?
Volcanic eruption, lava flow, cooling, and hardening
Melting, crystallization, solidification, and lithification
Weathering, erosion, deposition, compaction, and cementation
Sublimation, evaporation, condensation, and precipitation
Give an example of an extrusive igneous rock.
Granite
Obsidian
Gabbro
Basalt
What are the three main types of sedimentary rocks based on their origin?
clastic, chemical, and organic
limestone, marble, shale
granite, basalt, sandstone
igneous, metamorphic, volcanic
How do metamorphic rocks differ from igneous and sedimentary rocks?
Metamorphic rocks are formed through the alteration of existing rocks, while igneous rocks are formed from cooling magma/lava and sedimentary rocks are formed from accumulated sediments.
Metamorphic rocks are formed by rapid cooling of magma
Metamorphic rocks are formed from volcanic eruptions
Metamorphic rocks are formed by the accumulation of sediments
What is the most common type of igneous rock?
Granite
Obsidian
Pumice
Basalt
What are the two main categories of sedimentary rocks?
clastic and chemical
volcanic and plutonic
organic and inorganic
igneous and metamorphic
How do metamorphic rocks get their unique textures?
Recrystallization
Volcanic eruptions
Weathering
Erosion
