OakAn oak is a tree or shrub in the genus Quercus (ˈkwɜːrkəs; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably Lithocarpus (stone oaks), as well as in those of unrelated species such as Grevillea robusta (silky oaks) and the Casuarinaceae (she-oaks). The genus Quercus is native to the Northern Hemisphere and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa.
LightningLightning is a natural phenomenon formed by electrostatic discharges through the atmosphere between two electrically charged regions, either both in the atmosphere or with one in the atmosphere and on the ground, temporarily neutralizing these in a near-instantaneous release of an average of one gigajoule of energy. This discharge may produce a wide range of electromagnetic radiation, from heat created by the rapid movement of electrons, to brilliant flashes of visible light in the form of black-body radiation.
IndraIndra (ˈɪndrə; Sanskrit: इन्द्र) is the king of the devas (god-like deities) and Svarga (heaven) in Hinduism. He is associated with the sky, lightning, weather, thunder, storms, rains, river flows, and war. Indra's powers are similar to other Indo-European deities such as Jupiter, Perun, Perkūnas, Zalmoxis, Taranis, Zeus, and Thor, part of the greater Proto-Indo-European mythology. Indra is the most referred deity in the Rigveda.
