Answer:
True
Explanation:
Sound waves need a medium to travel through. That's why you cant hear sound in space. But you can see light in space and the sun heats up our planet, so yes, light doesnt need a medium to travel through.
The right answer is A.
The foreshore, also called intertidal zone, is the tidal zone of the tides on the coast. The alternation of the tides which discover more or less the substrate according to the phases of the Moon determines the conditions of humidity, salinity and temperature of the foreshore.
These variations lead to a vertical ecological structuring of the foreshore in so-called supralittoral, mediolittoral and infralittoral stages. The floristic and faunistic stands of these stages are distinct, according to the requirements of organisms in water, salinity and temperature. Therefore it would be beneficial for organisms living in this period that it can live without depending on the water present in their environment since the presence of the latter is inconstant.
The foreshore is divided into several floors that correspond to different ecological conditions. These coastal stages are defined by the duration of their emergence and therefore by the level of the different tides.
The population of the mice would most likely increase. This is because the number of predators of mice will decrease. Predators are those that feed on others, in this case mice. When predators decrease, the prey (which would be the mice) will be able to populate thus leading to an increase in population.
Because with out energy we wouldn't be moving and we would always be sleeping.
The correct answer is - Theory of the Ekman spiral
V. W. Ekman or Vagn Walfrid Ekman was a Swedish physical oceanographer. He is famous for his studies of the dynamics of ocean currents. Ekman developed a theory called as the “theory of the Ekman spiral”. This theory explains maintaining balance between frictional effects in the ocean and the Coriolis force. The force arises from moving objects in a rotating environment such as planetary rotation.
