The document discusses the formation of oceans on Earth. As the molten surface cooled over time, volcanic gases formed an atmosphere and water condensed from the atmosphere to form oceans. Life then emerged in the oceans. The three major oceans - Pacific, Atlantic, and Indian - formed as the supercontinent Pangaea broke apart. These oceans have varying depths, islands, currents, and features such as coral reefs and mid-ocean ridges. The document also describes how salinity and temperature vary in ocean waters due to factors like evaporation, rainfall, and ocean currents.
This document discusses how the earth's surface changes over time. It explains that tectonic forces such as earthquakes and volcanoes are driven by endogenic forces deep within the earth, as the lithospheric plates shift. These sudden movements can cause destruction. The document also outlines various exogenic or surface processes like weathering, erosion, sea waves, glaciers and wind that slowly shape the earth's landscapes over long periods of time by wearing down and transporting rock and sediment. Proper earthquake preparedness is also advised.

A plateau is an elevated flat land that stands above the surrounding area, with an elevation of around 500 feet above sea level. There are several types of plateaus, including intermontane plateaus surrounded by hills and mountains, volcanic plateaus formed by lava flows, dissected plateaus that have been eroded by rivers and glaciers, and piedmont plateaus bordered by mountains on one side and plains on the other. Examples of different types of plateaus mentioned include the Tibetan, Mexican, Peruvian, Deccan, Colorado, and Appalachian plateaus.
Plateaus are flat land areas that are higher than surrounding water bodies, characterized by steep slopes and flat tops. Plateaus are divided into three types - intermontane plateaus located within mountain ranges, piedmont plateaus found at the base of mountains, and continental plateaus that are higher than surrounding plains.
This document discusses different types of mountains, including fold mountains, block mountains, and relict mountains. Fold mountains like the Himalayas are the highest mountains and formed by the folding of tectonic plates. Block mountains such as the Black Forest have flat tops and steep sides caused by faulting of the land. Relict mountains like the Aravalli Range result from weathering that leaves resistant rock behind. The Himalayas influence India's climate and ecology.
Glacial landforms include erosional features like U-shaped valleys, hanging valleys, cirques, and arêtes, as well as depositional landforms like moraines, drumlins, eskers, and outwash plains. Glaciers erode through abrasion and plucking, forming characteristic steep-walled, flat-bottomed valleys. Cirques form at the head of valley glaciers. Depositional features include moraines of debris deposited or pushed along the sides and end of the glacier, as well as fluvio-glacial landforms formed by meltwater streams like eskers, kames, and outwash plains.
Poluarea este una din provocarile grave cu care se confrunta omenirea in ultimele decenii. Neavand granite, poluarea ne afecteaza mai mult sau mai putin pe fiecare din noi.
