The Earths process of changing one type of rock into another type of rock.

If an igneous rock experiences weathering and erosion, then goes through the process of lithification, what type of rock will it be?
Change into a Sedimentary Rock

Stay an Igneous Rock
None of the above
What is the difference between lava and magma?
Nothing is different.
Lava forms intrusive igneous rocks while magma forms extrusive igneous rocks.
Lava cools more slowly than magma.
Lava is found above ground, while magma is below ground.
Energy from the (a) causes weathering and erosion.
How are sedimentary rocks formed?
Tectonic plate movement and folding
Volcanic eruptions and lava cooling
Weathering, erosion, deposition, compaction, and cementation
Melting, solidification, and crystallization
What are the three main types of sedimentary rocks?
limestone, sandstone, shale
granite, marble, basalt
igneous, metamorphic, volcanic
clastic, chemical, organic
What are some characteristics of sedimentary rocks?
Formed through deposition and solidification of sediment, contain fossils, found near bodies of water, common types include sandstone, limestone, and shale
Contain only igneous rocks
Formed through volcanic activity
Found deep underground
How can sedimentary rocks be identified?
Smooth texture, high density, formed from volcanic activity
Layered appearance, presence of fossils, formed from accumulation and cementation of sediments
Crystalline structure, high porosity, formed from metamorphism
Amorphous shape, low hardness, formed from igneous rocks
What are some common uses of sedimentary rocks?
Food production, agriculture
Medical research, pharmaceuticals
Construction, building materials, cement production, source of lime, ceramics, glass manufacturing
Space exploration, rocket fuel
What is the process of lithification in sedimentary rock formation?
Evaporation and condensation
Melting and solidification
Compaction and cementation
Erosion and weathering
Give an example of a chemical sedimentary rock.
Sandstone
Shale
Limestone
Granite
Explain the difference between clastic and non-clastic sedimentary rocks.
Clastic rocks are formed by volcanic activity, while non-clastic rocks are formed by erosion.
Clastic rocks are only found in deserts, while non-clastic rocks are found in oceans.
Clastic rocks are always metamorphic, while non-clastic rocks are always igneous.
Clastic sedimentary rocks are composed of fragments of pre-existing rocks, while non-clastic sedimentary rocks are composed of organic or chemical sediments.
What role do fossils play in sedimentary rocks?
Fossils in sedimentary rocks provide evidence of past life forms and help in dating the rock layers.
Fossils in sedimentary rocks are always perfectly preserved
Fossils in sedimentary rocks have no scientific value
Fossils in sedimentary rocks are used for decorative purposes
41-45.
Answer the questions below after watching the video
What is the first step in the formation of clastic sedimentary rocks?

Wind
Rivers
Volcanoes
Glaciers
What results from the evaporation of water, leaving dissolved minerals behind?
Clastic sedimentary rocks
Chemical sedimentary rocks

Metamorphic rocks
Which organisms contribute to the formation of biochemical sedimentary rocks?
Coccolithophores
Dinosaurs
Mushrooms
Ferns
What type of environment is indicated by the presence of coal?
Marine environments
Deserts
Mountain streams
Tropical wetlands
How do sedimentary rocks contribute to the rock cycle?
Sedimentary rocks contribute to the rock cycle by transforming directly into metamorphic rocks
Sedimentary rocks contribute to the rock cycle by undergoing subduction
Sedimentary rocks contribute to the rock cycle by being weathered and eroded into sediment, which then gets compacted and cemented to form new sedimentary rocks. These rocks can also undergo metamorphism to become metamorphic rocks or melt to form magma for igneous rocks, thus completing the rock cycle.
Sedimentary rocks contribute to the rock cycle by forming directly from magma

How does water contribute to the weathering of rocks?

What role does water play in the erosion process?
It freezes and expands in cracks
It carries sediments to new locations
It breaks rocks into smaller pieces
It deposits minerals in new places
What happens during deposition?
Water evaporates leaving minerals behind
