地下水抽得太多，地面真的会下沉吗？
Can over-pumping groundwater really make the land sink?
会，这叫“地面沉降”。抽走地下水后，松散地层失去支撑被压密，地面就缓缓下沉，上海、华北平原都出现过。
Yes—land subsidence. Removing groundwater compacts loose strata, and the surface slowly sinks, as seen in Shanghai and the North China Plain.

山会不会自己“长高”？
Can a mountain grow taller by itself?
会。板块挤压、火山喷发能把地壳抬升，山就慢慢长高；当然风化和侵蚀也在不断把它削低，两者一直在比赛。
Yes. Plate collision and volcanism uplift crust, raising mountains; meanwhile weathering and erosion wear them down—a constant race.

沙漠里也会下雪吗？
Can it snow in the desert?
会。像塔克拉玛干这样的大沙漠，冬天夜里气温可降到零度以下，遇到冷空气和水汽就能飘起雪花。
Yes. Deserts like Taklamakan can drop below freezing on winter nights, and with cold air and moisture, snow can fall.

赤道附近也会有终年积雪的山吗？
Can there be snow-capped mountains near the equator?
有。像非洲的乞力马扎罗山，虽然在赤道，但海拔近6000米，山顶太冷，终年积着雪和冰。
Yes. Mount Kilimanjaro sits on the equator yet rises nearly 6,000 m, so its peak stays cold enough for year-round snow and ice.

石头也能漂在水面上吗？
Can a stone float on water?
能！火山喷出的“浮石”里满是小气泡，像海绵一样轻，丢进水里会浮起来。
Yes! Volcanic pumice is full of tiny bubbles like a sponge, so it is light enough to float.

死海的水为什么能让人浮起来、淹不死？
Why does the Dead Sea let you float and not sink?
死海盐特别多，水比普通海水重得多，浮力大，人躺上去自然漂着，很难沉下去。
The Dead Sea is extremely salty, so dense water gives huge buoyancy—people float easily and rarely sink.
