1. The world in spatial terms
The purpose of the first essential element of geography is to study the relationships between people, places, and environments by mapping information about them into a spatial context.
2. Places and regions
The purpose of the second essential element of geography is to show how identities and lives of individuals and peoples are rooted in particular places and in those human constructs called regions
3. Physical systems
The purpose of the third essential element of geography is to identify how physical processes shape the Earth’s surface and how they interact with plant and animal life to create, sustain, and modify ecosystems.
4. Human systems
The purpose of the fourth essential element of geography is to show how people are central to geography in that human activities help shape the Earth’s surface, human settlements and structures.
5. Environment and society
The purpose of the fifth essential element of geography is to show how the the physical environment is modified by human activities, largely as a consequence of the ways in which human societies value and use Earth’s natural resources.
6. The uses of geography

The reddish-orange colour of weathering of volcanic ash is most likely due to its iron sulfide content which oxidizes to iron oxide so that limonite is yellow and hematite is red and in ash since it is such fine grained material it weathers more rapidly because it has a large surface area.
Answer:
Two measures that have been introduced by the US and local governments to reduce the consumption of gas are the introduction of light-rail and the use of carpool lanes.
Explanation:
The introduction of light-rail will reduce the consumption of gas from personal vehicles and also reduce personal vehicle carbon emissions. One example is the Dallas Area Rapid Transit (DART) and Los Angeles has a system that combines light rail and heavy rail called Metro Rail. The use of carpool lanes will reduce the use of gas and help to reduce traffic congestion because there will be less cars on the road in high traffic areas where there is a large percentage of the population who commutes to and from work on freeways. Carpool lanes or High Capacity Vehicle (HCV) lanes are found in metropolitan areas like Washington DC.
