Answer:
1) the study of the world’s surface, physical qualities, climate, population, products, etc.
2) 4.543 billion years
3) Japan tops the list of the earthquake prone areas. The country has a long history of witnessing disastrous earthquakes since it is situated on the Pacific “Ring of fire”.
4) A tsunami is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions above or below water all have the potential to generate a tsunami
5) Moving water is the dominant erosional agent in deserts. Wind may also be a significant agent of erosion, and may cause characteristic land forms and surfaces. Removal of sand and silt sized particles by wind action is called deflation.
6) Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. 6 - 12+ Earth Science, Geology, Geography, Physical Geography.
7) Anemometers
8) Oceanography is the study of the physical, chemical, and biological features of the ocean, including the ocean's ancient history, its current condition, and its future. ... It is the study of the ocean's plants and animals and their interactions with the marine environment.
9) The salinity of seawater is defined as the total amount by weight of dissolved salts in one kilogram of seawater. Salinity is expressed in the unit g / kg, which is often written as ppt (part per thousand) or ‰ (permil). ... Over the years, various methods have been developed to determine salinity
10) The Earth is called a 'Living Planet' due to its certain features: It is the home of all forms of life such as plants, animals, and human beings because of its appropriate location from the Sun. ... The atmosphere and life supporting gases such as oxygen and its availability are also of significant importance on the Earth.
