1·Isotopic analysis of shells allowed geologists to measure another glacial effect.

对贝壳的同位素分析使得地质学家可以测量另一种冰川效应。

2·In all these diverse regions, Agassiz saw signs of glacial erosion and sedimentation.

在这些不同的地区，Agassiz 都能发现冰川侵蚀和沉降的痕迹。

3·The glacial system is governed by two basic climatic variables: precipitation and temperature.

冰川系统由两个基本的气候变量控制：降水和温度。

4·That rate of heating is far greater than during the last glacial retreat some 12,000 years ago.

这一升温速度远高于约1.2万年前的最后一次冰川消退。

5·When snowfalls on high mountains or in polar regions, it may become part of the glacial system.

当雪落在高山或极地地区时，它可能成为冰川系统的一部分。

6·Over the past two million years, colder glacial periods have alternated with warmer interglacial periods.

在过去的200万年里，寒冷的冰期与较暖和的间冰期交替出现。

7·Between the older layers of glacial material were well-developed soils containing fossils of warm-climate plants.

较古老的冰川物质层之间是发育良好的土壤，它含有（生活在）温暖气候中的植物的化石。

8·High carbon dioxide levels are associated with warm interglacial periods, and low levels with cold glacial periods.

高二氧化碳含量与温暖的间冰期有关，低二氧化碳含量与寒冷的冰期有关。

9·Ocean sediments presented a much more complete geologic record of the Pleistocene than continental glacial deposits did.

相比于大陆冰川沉积物，海洋沉积物提供了更完整的更新世时期的地质记录。

10·It soon became clear that there were multiple glacial ages during the Pleistocene, with warmer interglacial intervals between them.

很快我们了解到，在更新世存在多个冰川期，其间还包括多个温暖的间冰期。
