How do geographers use regions to make sense of locations? Geographers define regions as conceptual tools people use to break up the wide world into smaller, easier-to-think-about units based on a characteristic, or set of characteristics. This helps them to identify the area and places within a region’s boundaries. In fact, regions contain many places […]

How is a strait and an isthmus similar and different? Comparisons. Straits are the converse of isthmuses. That is, while a strait lies between two land masses and connects two larger bodies of water, an isthmus lies between two bodies of water and connects two larger land masses. What is a strait and isthmus? A […]

Answer: A host loses nutrients to a parasite. Explanation: A host-parasite relationship is called parasitic symbiotic relationship which means the host […]

What do ice cores tell us about climate change? Ice cores can tell scientists about temperature, precipitation, atmospheric composition, volcanic activity, and even wind patterns. The thickness of each layer allows scientists to determine how much snow fell in the area during a particular year. How do sediment cores tell us about past climate? Sediment […]

What is below the water table? Underneath the water table is the saturated zone, where water fills all spaces between sediments. The saturated zone is bounded at the bottom by impenetrable rock. The groundwater found below the water table comes from precipitation that has seeped through surface soil. Where groundwater reaches the land surface is […]

How do planetary wind belts affect the climate? On a planetary scale, the circulation of air between the hot Equator and the cold North and South Poles creates pressure belts that influence weather. Thus, a wind travelling north from the equator will maintain the velocity acquired at the equator while the Earth under it is […]

Why do areas near the equator have large seasonal changes in weather? For example, places near the equator have about the same tempera- tures and amounts of daylight all year. Seasons happen because Earth is tilted on its axis by about 23.5°. This tilt affects how much solar energy an area gets as Earth orbits […]
