Answer:
What is climate change?
Is the conversion of the current climate to a new climate due to geographic factors.
Explain how global warmings occurs.
When the gases like carbon monoxide reach the ozone layer, they react with the ozone gases hence fading away the layer, hence letting direct sunlight onto Earth's surface resulting to warming known as global warming.
Give the name of two (2) Greenhouse gases
- Carbon dioxide ( CO2 )
- Ozone gas ( O3 )
What are some things you can do to reduce global warming and climate change?
Fighting against pollution e.g the carbon monoxide gases released by industries, cars
Encouraging aforestation and re aforestration to maintain the climate
The Cenozoic era is the most recent era and includes the emergence of mankind and its' ancestors. It includes earth history from 66 million years to almost the present and also is known as the age of mammals which includes mankind. Evolution of the mammals can be traced relatively easily since there are most likely more abundant fossils than back in say the Cambrian or especially the Precambrian.

Explanation:
Energy can be defined as the ability (capacity) to do work. The various forms of energy are solar energy, electrical energy, chemical energy, thermal energy, wind energy, nuclear energy etc.
The Law of Conservation of Energy states that energy cannot be destroyed but can only be transformed or converted from one form to another.
Some of the terminologies associated with energy includes the following;
1. Fuel cell: produces electrical energy chemically. It is a technology that operates just like batteries but do not need to be recharged since it doesn't run down. Also, it comprises of two (2) electrodes which are: positive electrode (cathode) and negative electrode (anode), with an electrolyte embedded in between them.
2. Alternative energy: energy sources that are still in development. These includes energy source other than fossil fuels. Some examples are petroleum, diesel and coal.
3. Energy conservation: includes lifestyle changes. It involves energy saving actions in order to reduce the level of energy consumption such as daylight savings, energy saving bulbs, etc.
4. Ocean thermal energy conversion (OTEC): produces electrical energy using the temperature difference between two layers of water.
5. Energy efficiency: percentage of energy that does useful work. It determines the amount of work that can be done at a particular time.
In Southeast Asia, European influence was mostly limited to the Malay Peninsula and the Indonesian Archipelago.
