lesson 1 reviewteksreviewing vocabularyanswering the guiding questions1. comparing and contrasting explain the difference between a wadi and an oasis. how are they alike? 21b2. describing what physical features make the dead sea unique? 4d3. summarizing what climates are found in southwest asia? 21b4. making inferences which climate do you think is best for human settlement, and why? 4b, 21b

Explanation:

1. For question 1: A wadi is a dry riverbed that only holds water after rain, while an oasis is a fertile area in a desert with a permanent water source. They are alike as both are water-related features in arid Southwest Asia.
2. For question 2: The Dead Sea is the lowest land-based elevation on Earth (around 430 meters below sea level), has extremely high salinity (about 34.2%, 9x saltier than ocean water) which makes it impossible for most aquatic life to survive, and it is a salt lake with no outlet, only fed by the Jordan River.
3. For question 3: Southwest Asia has arid/hyper-arid (desert) climates covering most of the region, semi-arid steppe climates in transitional zones, and Mediterranean climates along the coastal areas of the eastern Mediterranean.
4. For question 4: Mediterranean climates (mild, wet winters and warm, dry summers) are best for human settlement. They support agriculture (growing crops like olives, grapes) with manageable water access in winter, have milder temperatures compared to extreme deserts, and coastal areas with this climate offer trade and transportation advantages.

Answer:

1. Difference: A wadi is a dry, intermittent riverbed; an oasis is a permanent, fertile water spot in a desert. Alike: Both are arid-region water-related features.
2. It is the lowest land elevation on Earth, has extremely high salinity that kills most life, and is a closed-basin salt lake.
3. Arid/hyper-arid (desert), semi-arid steppe, and Mediterranean climates.
4. Mediterranean climate; it supports agriculture, has mild temperatures, and coastal areas enable trade.
