DNA contains instructions for making the different molecules that a cell needs to grow and function. For example, proteins are made by translating mRNA.

<h3>What is DNA and what is its function?</h3>

DNA is the structure responsible for transmitting all genetic characteristics — such as eye, skin and hair color, physiognomy, among others — in the process of reproduction of living beings. In this way, the main function of DNA is to carry information contained in its sequences, called genes.

DNA is made up of two chains of polynucleotides (strand), which are made up of several nucleotides. Nucleotides are joined together by bonds called phosphodiester (phosphate group linking two sugars of two nucleotides).

Limestone deposits can help researchers learn about what the area was like
Ivahew [28]

Limestone deposits can help researchers learn about what the area was like  thousands of years ago as Limestone can contain fossilized plants and animals.

Explanation:

  • Limestone often contains fossils of shelled sea creatures. Entire reef formations and communities of organisms are found preserved in limestone.
  • The types of fossils found in limestone include coral, algae, clams, brachiopods, bryozoa and crinoids.
  • Limestone is a sedimentary rock made almost entirely of fossils.
  • Fossils are the remains of ancient plants and animals, like an imprint in a rock or actual bones and shells that have turned into rock. Fossils are found in sedimentary rocks and hold the clues to life on Earth long ago.
  • Limestone is composed of the mineral calcite; calcium carbonate. It often has variable amounts of silica in it, as well as varying amounts of clay, silt, and sand. Limestone rocks fall under the category of sedimentary rocks that are made from mineral calcite.

How one rock can be transferred into either of the other rock type
mart [117]

Rocks can be classified in to three main groups - igneous, sedimentary and metamorphic. These three different rock types can be found in distinct areas of the UK.

Igneous rocks - these rocks are a result of volcanic activity in the past, when Britain was close to a plate boundary. Some of the igneous rocks are due to lava erupting at constructive plate boundaries. When the lava reached the surface, it cooled and solidified to form basalt rock. An example of this is the Giant's Causeway in Northern Ireland.

Other rocks are formed by hot molten magma beneath the Earth's surface cooling and solidifying as an intrusive rock under the ground, such as granite. This is later exposed as the rocks above are weathered and eroded at the Earth’s surface.

Sedimentary rocks – these are made up of small particles of sand and rock, which have been transported by the wind, rivers and ice and are usually deposited on lake or seabed. Over many millions of years, successive layers of sediments accumulate. These layers of sediments are compressed by the weight of the deposits above, into sedimentary rocks. These rocks form in layers, known as bedding planes.

When sand is compressed it forms sandstone. When mud is compressed it becomes clay. Limestone and chalk come from the remains of dead plant, animal and marine species and are rich in calcium carbonate and contain fossils. Many of these rocks were formed over 300 million years ago, in warm tropical seas during the carboniferous period. The existence of these rocks is evidence that Britain was at a different latitude compared to today. This suggests movement of continental areas of the globe, which is explained by the modern theory of plate tectonics.

Metamorphic rocks - these are rocks that have been changed in shape and form by intense heat and pressure at a plate boundary or along a fault line. These rocks start as either igneous or sedimentary rocks and are crystallised under the intense heat and pressure conditions to form rocks such as slates, schists, and marble. These rocks are very hard in nature and are often used as roof material.

short answer

The three main rock types are igneous, metamorphic and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.
