Name the three major groups of rocks and describe how each forms?
The three groups are igneous, sedimentary, and metamorphic. igneous forms when magma or lava cools down. sedimentary forms when sediments (clay, sand, silt etc) gets compressed. and metamorphic forms when an igneous or sedimentary goes under very high temperatures and pressure
What causes sediments to harden into a rock?
Sediments harden to form sedimentary rock through the application of pressure. Heat may play a part, but it is the settling down of the sediment and the buildup of overburden that "crushes" the material together. After millenia in a "big squeeze" applied by zillions of tons of material that has been superpositioned, sedimentary rock if formed. A link can be found below to the Wikipedia post on sediment and on sedimentary rock.
Layers and layers of sand are deposited on the sea bottom to form what rock?
Seasonal, cyclical, or other event based depositions of sediment are called strata.
Scientists divide rocks into groups based on what?
Rocks are grouped by how they are formed. There are 3 types of rocks. Sedimentary, Metamorphic, and Igneous rock. Sedimentary rocks are made from broken down rocks, called sediment, which come from all three rocks. Metamorphic rocks come from existing rocks that are changed by heat and pressure. The Igneous rocks are formed from magma that rose up to the surface, also known as lava. When the lava cools and hardens it forms igneous rocks. That is a rock cycle.

What is difference between sediment and residue?
A residue is something that is left behind after a reaction that is undesired. A precipitate is the amorphous solid formed after a reaction and is usually the desired result.
Rock type that is formed when sediment is lithified?
Sedimentary rock can be formed from lithified sediments.
How does rock's form?
Rock forms through three processes. Sedimentary rocks are formed by the compression of sediment. Igneous rocks are formed when magma crystallizes after melting. Metamorphic rocks are sedimentary and igneous rocks that have been subjected to pressure and heat .
How is metamorphic rock is made from sediment?
Metamorphic rocks are formed by rocks sedimentary or igneous that change their form under intense heat and or pressure.
When sediment is deposited in layers what rock is formed?
sedimentary
What does sedimentary mean in geography?
It means "formed from sediment".
What Are Chemically Formed Sedimentary Rocks Formed From?
Chemically formed sedimentary rocks are formed from dead remains of plants and animals that is from an organic sediment.
What kind of sedimentary rock is formed when sediment is buried compacted and cemented?
Clastic or bioclastic sedimentary rock is formed in this manner.
When sediment is deposited in layers what rock is formed explain your answer?
sedimentary
What occurs when the weight of overlying sediment forces the sediment grains to fuse?
A sedimentary rock is formed.
Why was sedimentary rock named sedimentary rock?
Because the rocks are formed by using layers of Sediment.
Sedimentary rocks?
Sedimentary rocks are formed by the accumulation of sediments.
What is rocks formed from sediment deposits?
Sedimentary rocks. Example, sandstone.
