What causes the temp to decrease with height in the mesosphere? Within the mesosphere, temperature decreases with increasing height, due to decreasing absorption of solar radiation by the rarefied atmosphere and increasing cooling by CO2 radiative emission. The top of the mesosphere, called the mesopause, is the coldest part of Earth’s atmosphere. Does temperature increase […]

What are some long term consequences of desertification?
What are some long term consequences of desertification? Desertification reduces the ability of land to support life, affecting wild species, domestic animals, agricultural crops and people. The reduction in plant cover that accompanies desertification leads to accelerated soil erosion by wind and water. How can we reduce land degradation? 5 possible solutions to soil degradation […]
Is h20 dative covalent bond?
Is h20 dative covalent bond? H2O(l) + H+(aq) [H3O]+, a pair of electrons (a lone pair) from the oxygen atom of the water is donated to a proton to form an oxygen-hydrogen dative (co-ordinate) covalent bond in the oxonium ion. Is CO2 polar or nonpolar molecule? Polar molecules have a non-zero net dipole moment. Both […]

What are the two main sources of thermal energy?
What are the two main sources of thermal energy? 1. Describe three ways in which thermal energy is found in nature. Thermal energy is found in the sun (solar energy), below Earth’s surface (geothermal energy), and in fire and other chemical reactions, and decay. What are main sources of heat? Sun is the biggest source […]
What are the major steps in homeostasis?
What are the major steps in homeostasis? Adjustment of physiological systems within the body is called homeostatic regulation, which involves three parts or mechanisms: (1) the receptor, (2) the control center, and (3) the effector. The receptor receives information that something in the environment is changing. What happens to the body after exercise homeostasis? To […]

What does the slope of displacement time graph indicate?
What does the slope of displacement time graph indicate? A sloping line on a displacement-time graph shows that the object is moving. In a displacement-time graph, the slope or gradient of the line, is equal to the velocity of the object. The steeper the line (and the greater the gradient) the faster the object is […]
