2.Australia, Antarctica, South America
3. Africa, a bit of South America is also in the Northern hemisphere
4. The Equator
Explanation:
There are three types of fossil fuels: Oil, coal and gas.
Let's look into their formation one by one:
Oil: Dead plankton such as microorganisms and plants was buried under the sea million years ago, it accumulate over time to become oil, also known as petroleum,
Coal: Plants were dead and broken down by bacteria over time, carbon dioxide and methane were produced. After million years, the dead flora accumulated to become peat and undergone compaction, becoming coal.
Gas: This is formed along oil, and again produced by dead organisms. It is mostly formed during decomposition, and mostly made up of methane.

<u>Answer:</u>
<em>The mineral property of cleavage depends on the alignment of</em><u><em> 2. Atoms</em></u>
<em></em>
<u>Explanation:</u>
- Minerals which exhibit this property form crystals upon breaking.
- The property of cleavage is decided by the placement of atoms in the mineral crystal.
- The alignment of atoms is a determining factor of the direction in which the crystal will break when pressure is applied.
- Atoms placed at short distances to each other form strong bonds. Weak bonds are formed between the atoms which are at longer distances.
- When pressure is applied, the mineral crystal will break along the region having weaker bonds.
