B shield volcanoes is the correct answer!
So it can be used when having you know what with 2 other ppl a male and a female
The three basic steps that are common to all sensory systems are as follows:
1. They all receive sensory stimulation usually by means of specialized receptor cells.
2. They all transform the stimulations received into neural impulses.
3. They all transport the neural impulses to the appropriate section of the brain.
The answer is A. This is because, in a new environment, mostly of new bare rock can only support plants such as algae and moss (pioneer species). However, as they weather the rocks and soil begin to form, plants such as pteridophytes (ferns) begin to emerge. Eventually, when the soil is deep enough, higher plants such as shrubs and grass emerge and over time trees can grow.
Answer:
Concentrations of carbon dioxides are rising mainly due to energy-burning fossil fuels. Fossil fuels such as carbon or oil include carbon plants which, over the years, are photosynthesized in the atmosphere; in a few hundred years we have returned this carbon to the air
Explanation:
Even fundamental human functions — eating inhalation and digestion — generate CO2. In the life cycles of the earth, it is an essential chemical. Active plants and trees are absorbing CO2 and turning it into food with sunlight and water. There are problems when more CO2 is emitted than is absorbed by our vegetation. Activities to produce high carbon dioxide include:
- Consuming electricity: Fossil fuels emit CO2, with coal emitting twice as much gas as oil. Worldwide, 85% of energy is generated by fossil fuels. As China and India continue to industrialize, the number of coal-burning plants will rise. Today, power generation represents 41 percent of CO2 emissions in the United States.
- Transportation: Locomotive is the second greatest source for U.S. CO2 emissions for business or pleasure. Travel is also a factor internationally. A cruise ship study indicated that holidays at sea produce 12 times more CO2 than on land. 41,000 tonnes of CO2 was generated at Denmark's 11-day worldwide Copenhagen Conference on Climate Change. U.S. representatives alone produced sufficient CO2 to fill 10,000 Olympic pools.
- Building: Manufacturing produces large amounts of CO2, yet only represents 2% of US emissions. The most serious offenders are the manufacture of iron and steel and cement. These businesses use huge amounts of thermal energy to turn commodities into building products.
- Deforestation: Trees are powerful organisms that absorb CO2 from the air and remove it. It stops the process by cutting them down. While deforestation is a tiny source of increasing CO2 in the U.S., 20 percent of global CO2 emissions are due to forest loss. Fuel-burning trees and natural forest material breakdown also generate CO2.
