Question

most petroleum formation began in places that were oceans millions of years ago. during the time it took for petroleum to form, earth’s surface changed. places that were once oceans may now be dry land.
the map shows how much petroleum has been found in different places around the world, mostly in reservoirs beneath earth’s surface. some of these reservoirs contain more petroleum than others do. the amount of petroleum in a reservoir is typically reported in units of billions of barrels of crude oil (bbo). look at how petroleum is distributed, or spread out, across earth.
source data: based on data from the u.s. geological survey (usgs).
what is true about the global distribution of petroleum? select all that apply.

• petroleum has been found along the edges of continents.
• petroleum has only been found in the southern hemisphere.
• more petroleum has been found in asia than in australia.
• most places have the same amount of petroleum.

Explanation:

1. For "Petroleum has been found along the edges of continents": Looking at the map, regions like the edges of North America, South America, Africa, etc., have petroleum (shown by the color coding), so this is true.
2. For "Petroleum has only been found in the Southern Hemisphere": North America (Northern Hemisphere) has petroleum, so this is false.
3. For "More petroleum has been found in Asia than in Australia": Asia’s regions have darker (higher BBO) colors compared to Australia (mostly lighter), so this is true.
4. For "Most places have the same amount of petroleum": The map shows varying colors (different BBO ranges), so amounts differ, making this false.

Answer:

• Petroleum has been found along the edges of continents.
• More petroleum has been found in Asia than in Australia.
