Just like convection in air, when denser water sinks, its space is filled by less dense water moving in. This creates convection currents that move enormous amounts of water in the depths of the ocean.
Yea it is right 1950. Geography !
Answer:
A. Tsunamis:
Tsunamis usually cause the greatest amount of destruction in comparison to other waves. There are massive waves that can cause the destruction of most ecosystems.
Explanation:
- Tsunamis cause large displacement of the water bodies and are generally known as the killer waves.
- The tidal waves are a regular recurrent shallow body of water and affect the gravitational attraction between the sun and the Sun, Moon and the earth and maybe often referred to as tsunami but do not generate to the small tidal waves
- The wind-driven waves or the surface waves are those created by the formation of the surface water and them tens to blow away the occurs for the Oceana and are found across the open seas and globally across the coast. As compared to the tsunami that is tectonically produced these are due to the disturbance in the body of the water.
<u>Answer:</u>
Ptolemy accounted for 'retrograde motion' in his model of the solar system by introducing smaller circles named 'epicycles'.
<u>Explanation:</u>
- According to Ptolemy, the Sun and the other planets in the Solar system orbited around the Earth.
- The Greeks were convinced that Ptolemy's earlier model did not provide for backward or the retrograde motion.
- Ptolemy thought over it for a while and theorized the possibility of 'epicycles'.
- According to Ptolemy, the planets that orbited Earth also orbited another smaller point.
- The smaller orbits followed by the planets while in motion around the Earth in a larger orbit were introduced by Ptolemy as 'epicycles'.
- Until Kepler proposed his models of the functioning of the Solar system, Ptolemy's models were considered the most relevant.
Answer:
Deep underground, beneath an extinct volcano
Explanation:
Diorite results from the partial melting of a mafic rock above a subduction zone. It is found in volcanic arcs, and in cordilleran mountain building, such as in the Andes Mountains.
Diorite is formed <u><em>deep within the Earth's crust from cooling magma that never made it to the surface</em></u>. It usually occurs as quite small intrusions often associated with larger intrusions like granite. Slow cooling produces the large crystals.
