Chapter - Review:
- The solid section of the earth made up of rocks and soil is known as the lithosphere, and it is made up of rocks from the crust and layers of soil containing nutritional elements.
- The earth's surface is divided into vast landmasses known as continents and huge water bodies known as oceans, and these nutritional componen5ts sustain organisms on the planet. All of the world's oceans are linked.
- in all regions, the ocean level is the same. The elevation of the sea level is assumed to be zero, and elevations are calculated accorsingly. From here, a variety of differenty places are measured.
- Mount Everest is the world's highest mountain peak with an elevation of 8,848 meters above sea level.
- Because water covers more than 71% of the earth, it is commonly referred to as the "Blue Plant". The hydrosphere is made up of water in all of its forms, including flowing water in rivers, oceaus, and lakes, ice in glaciers water vapor in the atmosphere and subsurface water.
- The Oceans make up 97% of the hydrosphere. This water is excessively salty for human consumption.
- A large portion of freshwater is found in ice sheets and glaciers, asa well as subsurface water.
- The earth's oceans make up the majority of the hydrosphere. They're all linked together.
- The ocean currents are always moving, waves, tides and ocean currewnts all - cause movement in the ocean.
- The pacific ocean, the Atlantic ocean, the Indian ocean, the Southern oceans and the Arctic ocean are the world's oceans.
- The pacific ocean is the world's largest, covering one - third of its surface.
- Mariana Trench is located in pacific oceans and is the deepest portion of the earth. It encircles North and south America, Asia, and Australia and is typically round.
- The Atlantic oceans, the world's second - biggest oceans, is formed like an 's' and is bordered on the east by Europe and Africa and on the west by North and south America.
- The atmosphere is a blanket of air that surrounds the planet like a blanket and protects the biosphere from the destructive effects of sun rays.
