When the plates move they collide or spread apart allowing the very hot molten material called lava to escape from the mantle. When collisions occur they produce mountains, deep underwater valleys called trenches, and volcanoes. The Earth is producing "new" crust where two plates are diverging or spreading apart. When two plate move towards each other they converge or come together. The collision between two plates that are moving towards each other is called a convergent boundary. The collision results in large damaging earthquakes. When two continental plates converge the result is the formation of large folded mountains.

Igneous rocks are formed from the solidification of molten rock material. ... Examples of intrusive igneous rocks are diabase, diorite, gabbro, granite, pegmatite, and peridotite. Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there. Metamorphic rock can change into igneous or sedimentary rock. Igneous rock forms when magma cools and makes crystals. Magma is a hot liquid made of melted minerals. The minerals can form crystals when they cool.

Rocks that formed from magma are called igneous rocks. Igneous comes from the Latin word ignis which means "fire". Rocks that are formed from heat and pressure are called metamorphic rocks. Rocks that are formed from the cementing together of small pieces of rocks or shells are called sedimentary rocks. Igneous — they form from the cooling of magma deep inside the earth. Metamorphic — they are formed through the change (metamorphosis) of igneous and sedimentary rocks. They can form both underground and at the surface. Sedimentary — they are formed through the solidification of sediment.

(1) 4p-2=18
4p = 18 + 2
4p = 20
p = 20/4 = 5
(2) p+4=15
p = 15 - 4 = 11
(3) m-7=3
m = 3 + 7
m = 10

A jagir was a type of feudal land grant in the Indian subcontinent at the foundation of its Jagirdar (Zamindar) system. It developed during the Islamic rule era of the Indian subcontinent, starting in the early 13th century, wherein the powers to govern and collect tax from an estate was granted to an appointee of the state. The tenants were considered to be in the servitude of the jagirdar. There were two forms of jagir, one being conditional and the other unconditional. The conditional jagir required the governing family to maintain troops and provide their service to the state when asked. The land grant was called iqta, usually for a holder's lifetime, and the land reverted to the state upon the death of the jagirdar.
The jagirdar system was introduced by the Delhi Sultanate,[2] and continued during the Mughal Empire, but with a difference. In the Mughal times, the jagirdar collected taxes which paid his salary and the rest to the Mughal treasury, while the administration and military authority was given to a separate Mughal appointee.After the collapse of Mughal Empire, the system of jagirs was retained by Rajput, Jat, Saini and Sikh jat kingdoms, and later in a form by the British East India Company.
