Sunlight is the main source of energy that causes most waves to form on earth.
Explanation:
The energy from the sun is ultimately the driver of most waves on the earth. The sun rays heat up the atmosphere and oceans deferentially at different latitudes due to the spherical nature of the earth. This creates differences in temperatures, densities, and pressure over areas hence resulting development of waves such as wind-generated ocean waves. The sun causes different pressure systems that feed prevailing winds. The prevailing winds, at the boundary between the oceans and atmosphere, cause waves due to the force of drag as the winds blow predominantly in one direction.

Answer:
Intensity of heat, lack of water, and a blazing/searing sun.

Why are there so few humans and animals in the desert?</h2>
A desert is defined as a place with a hot and dry temperature, little or no rainfall (less than 25 cm), a barren landscape, a lack of water, and dry soil. There is very little vegetation. Plants appear only after rain, are seasonal, and have a short lifespan. Dust storms and shifting dunes may be dangerous. In other words, the circumstances are unfit for human occupancy. That is why relatively few people live in or near deserts. Animal life is likewise sparse, yet abundant in some areas. Some locations, such as Egypt's Nile Valley, may be heavily inhabited if enough water is available. In reality, air-cooling, air-conditioning, and irrigation facilities, as well as the discovery of petroleum wherever and whenever it was accessible, have made desert life more pleasant, dynamic, and have drawn people from outside, such as the Gulf area.
<h2>Why don't desert animals just move somewhere greener?</h2>
Deserts are a result of the Earth's atmosphere. Do you notice how deserts appear to be in similar zones? This is due to the tight link between deserts and rainforests. So this is what generates a desert, not what attracts or maintains animals here. Plants bring them and keep them alive. As plants adapt, so do animals, and the desert creates a complete ecosystem. They do not depart since they have adapted to their surroundings.

Answer:
The correct answer is: B. The amount of air in a room never changes.
Explanation:
- A system is said to be in equilibrium when the net components in the system remains constant (no increase or decrease) with time.
- The air in a room never remains constant and always undergoes dynamic movement into and out of the room. At equilibrium, the net air in the room remains constant as amount of air exiting the room is balanced by the amount of air entering it.
- Evaporation of water in the form of water vapour from a cup into the atmosphere is not in a state of equilibrium as the amount of water evaporating from the cup is not replaced in the cup so there is a net decrease in water level in the cup.
- The decrease in nitrogen percentage in a room is not in equilibrium as the nitrogen concentration of the room is not constant.
- A blade of grass growing taller is not in equilibrium as a constant height of the grasses is not maintained.
