Taiga is a Russian word that refers to an ecosystem characterized by snow and coniferous trees.
In English it is known as Boreal Forest or Snow Forest.
A large part of the Northern Hemisphere is made up of Taiga. Northern Russia, parts of Mongolia, Scottish Highlands, Northern Japan and Northern Canadian Provinces are all covered in Snow Forests.
The climate in these areas are generally cold and dry where a unique habitats has evolved comprising of Bears, Moose, Red Fox, Polar Bears etc.
The Andes Mountains are shared by Venezuela, Colombia, Ecuador, Peru, Bolivia, Argentina, and Chile.
Following are the correct options for this question:
- Build more windmills
- Develop cost-efficient solar energy
- Improve gas mileage in cars
- Reduce the use of nonrenewable energy sources
Any undesirable change occurs in the air due to addition of pollutants is called air pollution. The major air pollutants are sulfur dioxide which is released from the combustion of fossil fuels like coal, petroleum and from factories. Bedsides, sulfur dioxide dust and smokes are other pollutants. Building of more wind mills and developing low cost solar energy will reduce air pollution as they will provide clean energy and will reduce dependency on coal burning in thermal power plant. Improving as mileage in cars will also reduce emission of sulfur dioxide, hence reduce air pollution. Building of more wind mills and developing low cost solar energy are renewable source of energy, will reduce use of nonrenewable energy sources such as fossil fuels.
I think the inference that could be made is :
2. Earth's orbit has a greater distance between foci than the comet's orbit
both earth and comet has sun as their Foci, and from the diagram, the distance between earth and sun is far greater
Geothermal energy is not a fossil fuel.
