Question

notes - how geography shapes biomes - desert - _ - rainforest - _ - savanna - _ - chaparral - _ 7. key takeaway - insolation, _, and _ all work together to determine biome distribution - geography + climate = _ 8. quick check 1. what is the rain shadow effect? _ 2. why are island species often unique? _ 3. how do coastlines influence rainfall? _

Explanation:

1. The rain - shadow effect occurs when moist air rises over a mountain range, releases precipitation on the wind - ward side, and then descends on the leeward side as dry air, creating a rain - shadow area with less precipitation.
2. Island species are often unique because of geographical isolation. This isolation limits gene flow with mainland populations, allowing for the evolution of distinct traits through processes like genetic drift and natural selection.
3. Coastlines can influence rainfall in several ways. Oceanic air masses can bring moisture to the coast, leading to higher rainfall near the coast. Coastal mountains can also force air to rise, causing orographic precipitation.

Answer:

1. The rain - shadow effect is when moist air rises over a mountain range, drops precipitation on the wind - ward side, and the descending air on the leeward side is dry, resulting in a rain - shadow area with less rainfall.
2. Island species are often unique due to geographical isolation which restricts gene flow with mainland populations and allows for the evolution of distinct traits via genetic drift and natural selection.
3. Coastlines can influence rainfall as oceanic air masses bring moisture to the coast, and coastal mountains can cause orographic precipitation by forcing air to rise.
