Are two forms of sedimentary rocks are chemical and extrusive true or false?
answer:true
How do you classify rocks?
Geologists classify rocks by looking at their chemical and mineralogical composition then at the the size and shape of their component minerals then at any texture, pattern or grain that the rocks may display. They also classify them in relation to how they were formed.
Is a sedimentary rock or a metamorphic rock harder to sculpt?
Metamorphic rocks are formed from sedimentary and igneous rocks. When sedimentary or igneous rock is subjected to heat and pressure, the rock gets compressed. Therefore, if you had the same amount of metamorphic rock and sedimentary or igneous rock, the metamorphic rock would be heavier, because there is more 'stuff' in the metamorphic rock. ---------------------------------------------- However please note: There are types of igneous rocks that are hard (eg granite) and others that are soft (eg volcanic ash). There are types of metamorphic rocks that are hard (eg gneiss) and others that are soft (eg marble). Thus "hardness" is not a characteristic that can be used to distinguish between the two.
What are the two factors that changes igneous and sedimentary rocks to become the third type of rock called metamorphic rocks?
I just learned this in school. The two factors in the rock cycle to form metamorphic rock are extreme heat and/or pressure
What makes sedimentary rocks different from other rocks?
Igneous is basically fresh out of a volcano. There are two types: rocks that got cooled slowly, and those that were cooled really fast. After a while, these rocks will break down into sediment, and will form into layers. Then the sediment will go through cementation, where they stick together. At that point, its sedimentary rock! (Like sandstone, in the Grand Canyon!)
What are two examples of sedimentary rocks?
Limestone or Sandstone are two examples of sedimentary rocks. Two examples of sedimentary rocks are slate (fine silt) and chalk (shell remains of sea creatures).
What are sedimentary rocks shaped like?
No two sedimentary rocks are shaped the same, there are many different shapes
What are two types of organic rocks?
sedimentary and metamorphic rocks
What are the two main types of sedimentary rocks?
Clastic (those formed of particles of other rocks) and non-clastic (organic and chemical precipitate or evaporite rocks).
WHAT ARE two types of sedimentary rocks and describe what they are made from?
residual deposits and sedimentary deposits
What are different types of sedimentary rock?
Coal and Sandstone are two types of sedimentary rocks.
What two things do sedimentary rocks record?
Sedimentary rocks record; 1. Time (Age) of formation. 2. Environment of formation.
What two kinds of rocks are formed from all thre kind of rocks?
Sedimentary and metamorphic rocks.
What are the two major divisions of literature genre?
The two major divisions are prose and poetry.
What are sedimentary rocks form from dissolved minerals called?
They are called chemical sedimentary rocks. Rock salt and rock gypsum are two examples.
One of two ways that sedimentary and igneous rocks can be changed into metamorphic rocks?
sediment
Which two rocks are made from rounded grains?
Rocks that are composed of rounded grains or fragments are usually sedimentary rocks. Two of these are sandstone and conglomerate rocks.
