Classification of igneous rocks

Classification of igneous rocks

Igneous rocks are rocks formed from molten magma. The material is made liquid by the heat inside the Earth’s mantle. Igneous rock occurs in two ways. Slow cooling: Igneous rock formed from magma that has become solid inside the earth … more

Formation Model of Columnar Joint

Formation Model of Columnar Joint

Formation of Columnar Joint A columnar joint appears as a polyhedral pillar, such as a tetragonal, pentagonal, or hexagonal shape. Its shape depends on the rate at which the lava solidifies. Columnar joints are often mistakenly known to be hexagonal … more

Equilibrium of Radiation

Equilibrium of Radiation

Radiation Places close to the stove feel warmer than places farther away. This is because heat is transferred directly from the stove without any movement of material. This phenomenon in which heat is transferred directly without the aid of a … more

Water vapor in the air Liquid water can evaporate and turn into water vapor in the air. Conversely, water vapor in the air may turn back into the water. Some are very dry, with no moisture at all, such as … more

Psychrometer(hygrometry)

Psychrometer(hygrometer)

hygrometer It is a simple device that allows you to determine the humidity by measuring the difference in how much water evaporates. Compared to a simple structure, humidity can be measured relatively accurately. Before electronic hygrometers became popular, psychrometers were … more
