Which of these is a type of green energy?
Green energy is any energy type that is generated from natural resources, such as sunlight, wind or water. It often comes from renewable energy sources although there are some differences between renewable and green energy.
What kind of bag is most eco-friendly?
Eco-friendly earth-friendly or not harmful to the environment . This refers to products that contribute to green living or practices that help conserve resources like water and energy. Eco-friendly products also prevent contributions to air, water and land pollution.
How much of earths water we can use?
Fresh water makes up under 3% of all water on earth, and nearly 65% of this drinkable water is tied up in glaciers. Rivers, streams, lakes, and dams that hold freshwater contain 1% of potable water while groundwater accounts for 0.3%.
When is World Environment Day observed?
The United Nations, aware that the protection and improvement of the human environment is a major issue, which affects the well-being of peoples and economic development throughout the world, designated 5 June as World Environment Day.

The most abundant gas on the earth’s atmosphere is
By far, the most abundant gas in the Earth's atmosphere is nitrogen, which accounts for about 78% of the mass of dry air. Oxygen is the next most abundant gas, present at levels of 20 to 21%. Both of these gases occur as diatomic molecules. The amount of water vapour in the air is particularly relevant to weather forecasting. The gas composition helps us understand the effects of natural and man-made chemicals released into the atmosphere.
What atmospheric layer has most of the clouds?
Gravity, combined with the compressibility of air, causes the density of an atmosphere to fall off exponentially with height, such that Earth's troposphere contains 80% of the mass and most of the water vapor in the atmosphere, and consequently most of the clouds and stormy weather.
What are arboreal animals?
