Banks of the river. A slope of land adjoining a body of water
Collide. To come together with violent, direct impact.
Crust. The solid, outermost layer of the Earth, lying above the mantle.
Mantle. The zone of the Earth between the core and the crust.
Core. The central portion of the Earth, and it's consisting of iron and nickel.
Tectonic plates. Large rigid blocks, that floating on semifluid rock.
Debris. An accumulation of relatively rock fragments.
Moraines. An accumulation of stones or debris carried by a glacier.
Mud. Wet,sticky and soft earth as on the banks of a river.
Shallow. Measuring little from bottom to the top or surface.
Tides. The periodic variation in the surface level of the oceans caused by the gravitational attraction of the moon and sun.
Inlets. Is an indentation of a shoreline, that often lead to a body of salt water.
Cliffs. Vertical rock exposure, formed by erosion of the water.
LAND AND COASTAL RELIEF
Mountain. High elevation on the Earth's surface, which can be grouped in mountain ranges.
Valleys. Areas of lowland surroundesd by uplands,often with a river running through.
Ravine. Very deep and narrow,between steep mountain slopes.
Canyon. Very deep area, between vertical mountain faces.
Glacial valley. Formed by a glacier into V-shape.Deep coastal valleys are called fjords.
Plateau. Large areas of flat or slightly hilly land and unlike plains,higher than the land around them.
Plains. Large areas of flat or slightly hilly land not much higher than sea level,formed by accumulation of sediments from erosion.
Glacier. Large mass of ice that forms at the top of a mountain and moves like a river.When the ice melts,the debris forms deposits of stone and mud called moraines.
Stream. Flow of water with less volume than a river,which can dry up at certain times of the year.
Delta. Accumulation of materials (sand and stones) deposited by the river in a shallow part of the coast where it meets the sea.
Estuary. Mouth of a river open to the sea originates on coasts with strong tides.
Gulfs. Are deep inletsof the sea.
Beaches. Are formed on low coasts by the accumulation of sand and gravel.
Capes. Are the large areas of high coastal land that stick out into the sea.
Cliffs. Are high,steep and rock faces, especially at the edge of the sea.
RELIEF ON THE OCEAN FLOOR
Continental shelf. Is a submerged plain,which is an underwater extension of a continent.
Abyssal plain. Is a large expanse of land at the bottom of the ocean.Here we find trenches (long sunken areas) and ocean ridges (underwater mountain ranges)
Continental slope. Is the incline from the continental shelf down to the abbysal plain.
