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

Igneous:- Formed by the cooling of magma
Metamorphic:- Made by great heat and pressure

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.

Describe can metomorphic rock are classified what are the characteristics of rocks in each of these classifications?
they are classified by how they are classified
What is the class that includes sedimentary rocks which are deposited from a solution made by organic processes?
Sedimentary rocks are broken into two classes: clasticand chemical. Clastic sedimentary rocks are composed of rock particles, and chemical sedimentary rocks are composed of precipitation of minerals in solution.
Describe the dirction in which soil and rocks particles to fall?
Things fall in the direction that we call "down". BTW, "down" may point in different "absolute" directions.
How do chemical rocks form?
The key is the sediments. ... Biochemical sedimentary rocks are formed from organic processes that involve living organisms producing the sediments. These living organisms can be snails and clams whose discarded calcium carbonate shells can form limestone.
What do the three major groups of rocks have in common?
The three major groups of rocks have several things in common. The mineral composition is the same and this is why they will all turn into each other at some point.
Describe how a vein of ore forms underground?
Hot fluids that get into the cracks and rocks and it cools and settles.
Which major group or groups of rocks are involved in the description of pathway 2?
Metamorphic and Sedimentary
What do the three Majors rocks groups have in common?
The three major groups of rocks have several things in common. The mineral composition is the same and this is why they will all turn into each other at some point.

Agree. Sedimentary, igneous, and metamorphic
What are the groups of rocks?
They are Sedimentary rocks, Igneous rocks, and Metamorphic rocks.
Briefly describe the five major process involved in the formation of sedimentary rocks?
Weathering, Erosion, Deposition, Compaction, & Cementation.
What kind of rocks forms by recrystallization?
