Climate and natural vegetation: แบบฝึกหัด

• a.

  Descending high-pressure air that cools as it reaches the surface.

• b.

  Rain shadow effects created by high mountain ranges.

• c.

  Convectional rainfall caused by high temperatures and evaporation.

• d.

  Frontal rainfall caused by the meeting of warm and cold air masses.

• a.

  The growth of thick, succulent stems to store water and deep taproots to reach the water table.

• b.

  The shedding of leaves during a distinct dry season to reduce transpiration and conserve energy.

• c.

  The development of buttress roots to support great heights and waxy leaves with drip-tips to shed excess water quickly.

• d.

  The evolution of narrow, needle-like leaves and a conical shape to shed heavy snowfall.

• a.

  Descending air in high-pressure belts warms up and absorbs moisture from the ground, preventing cloud formation.

• b.

  Cooler air from the poles meets warm tropical air, forcing the warm air to rise and form steady, light drizzle.

• c.

  Moisture-laden winds are forced to rise over mountain ranges, cooling and condensing on the windward slopes.

• d.

  Intense solar heating causes air to rise, cool, and condense into cumulonimbus clouds, leading to heavy thundery showers.

• a.

  Mild temperatures all year round with the warmest month averaging \(15^{\circ}C\).

• b.

  Large annual temperature ranges exceeding \(20^{\circ}C\) due to seasonal changes.

• c.

  High temperatures throughout the year with a very small annual range of approximately \(3^{\circ}C\).

• d.

  Very high temperatures in summer but dropping below freezing in winter months.

• a.

  The presence of the Inter-Tropical Convergence Zone (ITCZ) ensures that the sun is always directly overhead, causing extreme seasonal heat.

• b.

  Cloud cover during the day reduces incoming solar radiation, while clear skies at night allow heat to escape, creating larger daily fluctuations than the small seasonal variations caused by the high sun angle.

• c.

  The high altitude of most rainforests leads to rapid cooling at night, whereas the annual range is stabilized by ocean currents.

• d.

  Strong trade winds blow consistently throughout the year, preventing any significant change in daily temperatures compared to seasonal shifts.
