Changes in pressure or heat create metamorphic rock. Water and wind create sedimentary rock. (Each rock group includes hundreds of different kinds of rocks.) Like the world's oldest blog, rock reveals millions of years of events and change. It shares how and when the earth's features, like mountains, oceans, or canyons were shaped.
Rock Pictures Each set of rock pictures is listed alphabetically by the common name of the rock. Clicking on the rock name will lead to a thumbnail page that displays all available photographs for that particular rock. I dedicate most of my time photographing minerals, so pickings will be slim in the rock section for a long time to come.

Sediment and sedimentary rocks • Sediment • From sediments to sedimentary rocks (transportation, deposition, preservation and lithification) • Types of sedimentary rocks (clastic, chemical and organic) • Sedimentary structures (bedding, crossbedding, graded bedding, mud cracks, ripple marks) • Interpretation of sedimentary rocks
Sedimentary Rocks Facts Interesting Sedimentary Rocks Facts: Sedimentary rocks are extremely important resources that give us clues about the Earth's past. Sedimentary rock has layers of sediments that are arranged according to their density. Compaction is the process by which sediments form sedimentary rock.
The rock cycle is a web of processes that outlines how each of the three major rock types—igneous, metamorphic, and sedimentary—form and break down based on the different applications of heat and pressure over time. For example, sedimentary rock shale .
Jun 19, 2019· Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water. Sedimentation is the collective name for processes that cause mineral and/or organic particles (detritus) to settle in place.
An introduction to SEDIMENTARY ROCKS. Sedimentary rocks form from sediment. "Sediment" is a general term that indicates loose grains (such as the sand at the beach) and chemical precipitates (such as crystals of salt). Sedimentary rocks can be subdivided in three categories: clastic, chemical, and biochemical sedimentary rocks.

Chert is a hard and compact sedimentary rock, consisting dominantly of very small quartz crystals. Chert occurs mostly in carbonate sedimentary rocks as nodules or layers. Flint is a darkcolored variety of chert.^ Coal is a combustible rock containing more than 50% by weight of carbonaceous material. Coal in most cases is a lithified peat.
Rocks are classified into three distinct groups igneous, sedimentary, and metamorphic and each is discussed in a separate section. Each rock group is further subdivided into subgroups that are defined by the mode of origin of the rocks. Igneous rocks form when magma, molten rock, rises upward
The rock cycle is a web of processes that outlines how each of the three major rock types—igneous, metamorphic, and sedimentary—form and break down based on the different applications of heat and pressure over time. For example, sedimentary rock shale .
Sedimentary rocks come from the fragments of preexisting rocks called sediments. There are three types of sedimentary rocks, each coming from different kinds of sediments. Clastic sedimentary rocks are created from the broken pieces of other rocks, while chemical sedimentary rocks form from mineral crystals like halite and gypsum.
The three types of rocks—igneous, sedimentary, and metamorphic—are all subject to processes that change one rock type into another. The images below show several types of rocks undergoing these processes. Just as evaporation and precipitation are processes that move water through the water cycle, igneous, sedimentary, and metamorphic rock ...
The main difference between Igneous, Sedimentary and Metamorphic rocks, is the way that they are formed, and their various textures. Igneous rocks are formed when magma (or molten rocks) cool down, and become solid. High temperatures inside the crust of the Earth cause rocks to melt, and this ...

It is a widely used raw asset in the construction industry. The extraction of hard rock that is turned into various crushed stone grades is a great economic indicator.
Teaching rocks for kids can be fun, interactive and even yummy with these creative ideas. These 15 activities and ideas are perfect for teaching science about rocks that includes the rock cycle, the types of rocks .
Sedimentary rocks are porous and can easily be weathered or worn down. Igneous rocks are formed from magma which is a hot, liquid found inside the earth. This either cools and forms rocks under the earth's surface, or flows out of erupting volcanoes as lava and may mix with other minerals. It cools it forms new rocks.
Igneous rocks are molten rocks expelled as lava that has cooled and become solid. Metamorphic rocks, on the other hand, are transformed rocks as a result of exposure to extreme heat and pressure beneath the earth's mantle. Sedimentary rocks are generally formed by .
