What is the difference between sea breeze and land breeze.?
Sea breeze blows from the sea to the land occurring during the day when the land heats up faster than the water. Land breeze blows from the land to the sea, happening at night when the land cools down more rapidly than the water.
WHAT IS THE DIFFERENCE BETWEEN TEMPERATURE AND THERMAL ENERGY?
TEMPERATURE is a measure of the average kinetic energy particles, WHILE THERMAL ENERGY is the total kinetic energy of particles
Describe what is upwelling and its importance for biodiversity.
The warm surface water is replaced by cold, nutrient-rich water from the deep ocean. Upwelling is important because it supports the ocean life and the growth of phytoplankton and zooplankton.
It is important because it absorbs most of the solar radiation such as ultraviolet radiation, which is harmful for life. Without it, humans' skin woul get affected causing illness such as cancer, etc
