早期的地球和太陽系
地形和環境
- 現在廣泛提供的地形數據能否用來推導出過去的構造和氣候條件(在幾百萬年的範圍內)?
- 我們對侵蝕和運輸過程有足夠的了解嗎?
- 氣象和構造事件的隨機性是否反映在景觀中?生命對塑造地球表面有多大貢獻?
- 滲透或向源侵蝕等經典地貌學概念能否定量理解? 阿巴拉契亞山脈或烏拉爾山脈等古老山脈似乎在 >108 年內保持地勢,而自新近紀以來,南極洲下的冰下河谷在千米厚的移動冰層下得以保存。 是什麼控制了地形衰減的時間尺度?[5]
- 是什麼支配地球表面演變的侵蝕和運輸規律?[6]河流運送的沉積物顆粒既是侵蝕的工具,也是保護基岩的盾牌。沉積物的這種雙重作用對環境的演變有多重要?[7][8]
- 海洋對化學污染的復原力如何?
- 是什麼控制了風暴軌跡的時態變化?[9]
