题目内容
【题目】（题文）读模拟湿润气候的形成条件，完成题目。
工具材料：三只小塑料杯、少量干燥的沙子、少量清水。实践步骤：①在两只小塑料杯中倒入等量的水，另一只杯子装入等量的沙子。②在每只杯口盖上一张透明的塑料薄膜，用橡皮筋扎紧。③把水杯A和沙杯B放在阳光下，水杯C放在阴凉处。④15分钟后，观察A、B、C三只杯子发生的变化。
(1)在步骤④中，观察A、B、C三只杯子，塑料薄膜上有明显水珠的是________，未发生明显变化的是________。
(2)根据实验观察结果，推测上图中P地的气候类型、气候特点并分析降水形成原因：
气候类型____________；气候特点____________；降水成因_______________。
【答案】(1)A C
(2)热带雨林气候 全年炎热多雨 湿润空气受热膨胀上升，变冷凝结而形成降水
【解析】
（1）一般认为，降水形成有两个基本条件：空气中含有足够的水汽；空气温度下降到水汽能够凝结出来的程度．结合实际生活，A杯中的水手阳光的照射，水汽会膨胀上升，塑料薄膜上形成水珠，在可判定：在步骤④中，观察A．B．C三只杯子，塑料薄膜上有明显小水珠的是A，未发生明显变化的是C。
（2）P处赤道附近，气候炎热，四周临海，湿润空气受热膨胀上升，变冷凝结而形成的降水，叫对流雨．所以气候特点应该是全年炎热多雨。
