What type of rock is granite?

Granite is formed by the cooling and solidification of magma below the Earth's surface, which allows for the growth of the quartz and feldspar crystals it contains. It is the counterpart of the extrusive igneous rock known as rhyolite. The minerals in granite may be pink, white or gray, depending on their chemical composition. Granite is a highly dense and hard material and is used in many applications including construction and engineering due to its strength.

What animals eat anaconda snakes?

The anaconda, or as it is known scientifically, green or common anaconda, is a native of South America's rain forests and wetlands. It is the biggest snake in the world, measuring more than 30 feet in length and 12 inches in diameter. It weighs over 550 pounds. The anaconda is a member of the boa family, and its method of hunting is the same as that of the rest of the family. The snake goes around its prey's body and strangles it with its muscles. Afterwards, the anaconda opens its stretchy jaws and engulfs the animal whole. The anaconda's habitat is the dark waters of rivers an..

Why is Venice sinking?

Venice is sinking at a rate of approximately 0.08 inches per year. The sea level around Venice is rising at almost the same rate, exacerbating the problem. Both the city and the land of the surrounding lagoons is sinking. Satellite measurements between the years 2000 and 2009 indicated that the sinking had stopped after the groundwater pumping ceased, but subsequent GPS techniques revealed that the city has continued sinking.\nAs a consequence of both the sinking of the city and sea level rise, flooding is becoming more common in Venice. Plank walkways must now be used several times a year to ..

What is the chemical formula for iron (III) oxide?

Iron (III) oxide results naturally when iron and oxygen come into contact at high temperatures. The reaction that takes place is written as follows: 4Fe + 3O2 ? 2Fe2O3. Iron (III) oxide is also produced synthetically. During this process, iron salts, such as ferrous sulphate, are calcined under oxidizing conditions. Depending on the specific conditions under which the reaction takes place, the resulting compound presents various colorations. Iron (III) oxide does not have carcinogenic properties.

What are compound eyes?

Each ommatidium contains its own lens, crystalline cone, visual cells and pigment cells. A single ommatidium is responsible for only a tiny section of the visual field. The compiled information from all the ommatidia in each compound eye creates a composite image. Greater numbers of ommatidia produce a higher-quality picture than fewer ommatidia. An insect, such as a grasshopper, with fewer ommatidia has a coarser, lower-quality image than an insect with more ommatidia, such as a honeybee. Although the honeybee may have good vision compared to other insects, its vision still has only one-sixti..

What is the hardest rock on Earth?

While many cite diamonds as the hardest rock on Earth, this is incorrect. Diamonds are not a rock. They are a mineral. Minerals are a "naturally occurring, inorganic (not alive) solid," as MadSci explains. They also have a crystal-shaped structure. Rocks are a little different. They contain one or more minerals, but are not minerals themselves. Granite, for instance, is made of quartz and other minerals, often feldspar and biotite.

How are fungi and plants similar?

Despite their similarities, plants and fungi differ in important ways. Plants are autotrophs, meaning they can generate their own food, while all fungi require food from external sources. Like plants, fungi can reproduce sexually or asexually, by casting spores, but some fungi mate by completely merging their own DNA with that of a partner in a process that has no analogue among plants or animals.

How do you make hydrogen?

Prepare the materialsGather two paperclips, a 9-volt battery and water. Divide the water into two separate containers: a bowl, and a test tube or small jar. Then, straighten the two paperclips into a line.Attach the paperclipsAttach one end of a paperclip to the positive side of the battery. Then, attach the one end of the other paperclip to the negative side of the battery. Put the free ends of each battery into the bowl of water without letting them touch.Capture the hydrogenThe paperclip end that is creating more bubbles in the water is the one that is hydrogen. It can be tested by putting ..

What is the application of physics in daily life?

Driving a car requires a basic understanding of the principles of physics, whether the driver is conscious of them or not. For instance, the balance of a car changes as the car accelerates, decelerates or turns. To keep the car on the road, the driver must anticipate these forces acting on the car and make adjustments.\nHaving an understanding of physics may also help an individual to lift something heavy. For example, by using a simple machine such as an inclined plane or a lever, an individual can make the load easier to lift. Physicists study simple machines extensively and use the lessons ..

In which era do we live today?

According to LiveScience.com, the Quaternary (fourth) geological era describes the most recent 2.6 million years, including modern times. It culminates into the Holocene Epoch, which describes the retreat of the glaciers and the last 12,000 years. According to UCMP Berkeley, the Cenozoic Era of evolution and animals describes the last 65 million years, from the extinction of the dinosaurs up until the modern day. It is sometimes called the "age of mammals."
