The diagram shows how air circulation forms a sea breeze on a warm day.

which best describes what is happening in the diagram?

at point 1, the air in the convection current is warmer and denser than at point 3 because its molecules contain more kinetic energy.
at point 2, the air absorbs thermal energy from the surrounding air, which causes it to become heavier and sink.
at point 3, the air in the convection current is cooler and lighter than the air in other parts of the current, so it is preparing to rise.
at point 4, thermal energy from warm air over the land is transferred upward toward cooler areas of the atmosphere.

According to the attached diagram it seems that a water cycle is depicted using warmer and colder temperature changes.

Wherein, the warm air rises from the surface of the sea due to evaporation and heat produced from the sun. Once the warmer air reaches to a comparatively cooler region it sinks down and goes back to the sea. This cycle continues in the nature. Due to the thermal energy produced by the sun the warm air rises upward from the sea and reaches the cooler areas of the temperature.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
