The single MOST important factor contributing to the modern-day extinction of hundreds of species on Earth is A) acid rain. B) invasive species. C) greenhouse effect. D) habitat destruction.


The correct answer would be option D. Habitat destruction.

Habitat destruction contributes the most in the loss of biodiversity these days.

More and more space is required to fulfill the demands of increasing human population.

More and more natural habitats are being destroyed for building houses, agriculture, building dams, roads, pipes, industries et cetera.

Consequently, a large number of wild species die due to lack of resources.

The demand on the Earth's lithosphere is dramatically increasing. Why should we look for alternative sources of energy other than just relying on fossil fuels? A) Fossil fuels are non-renewable and exhaustible and their combustion causes air pollution. B) Fossil fuels are renewable and plentiful, but their combustion causes air pollution. C) Fossil fuels are plentiful, so alternative sources are not needed. D) Fossil fuels are not profitable for energy companies.

A. the reason they are called non-renewable resource is that it takes a long time to for them to regenerate-basically longer then our lifespan. Also they do cause air pollution-which is causing the green house affect that is putting the demand on Earth's Lithosphere.

Biogeochemical cycles _______. a. are not essential for life b. move through abiotic and biotic regions c. are the result of natural disasters d. provide the greatest amount of energy for the Earth

The correct answer is B. Move through abiotic and biotic regions


The biogeochemical cycles refer to different natural cycles such as the oxygen cycle, the water cycle or the sulfur cycle that guarantee different substances and elements that are essential for life and Earth move. Indeed substances in biogeochemical cycles travel through abiotic or non-living regions such as the atmosphere or the soil but also involve biotic ones including ecosystem, animals, and plants. According to this, biogeochemical cycles move through abiotic and biotic regions.

QUESTION POSTED AT 27/03/2020 - 12:47 PM

Why is the term global warming often used when referring to climate change? Every location on earth is hotter every year than the year before. The sea temperatures have increased by 20 degrees. On average, the overall trend for the earth's surface temperature is increasing. None of the above are true.

The greenhouse effect occurs naturally, providing a habitable climate.Atmospheric concentrations of some of the gases that produce the greenhouse effect are increasing due to human activity and most of the world's climate scientists consider that this is a significant part of the cause of observed climate change.The oceans are a critical part of the climate system, with vastly greater thermal capacity than the atmosphere. Most of the net energy increase in the climate system in recent decades is stored in the oceans. A small, slow increase in their temperature is significant.Over one-third of human-induced greenhouse gas emissions come from the burning of fossil fuel to generate electricity. Nuclear power plants do not emit these gases.

The "greenhouse effect" is the term used to describe the retention of heat in the Earth's lower atmosphere (troposphere) due to concentrations of certain trace gases and water vapour in the atmosphere. These gases are generally known as greenhouse gases*. Concentrations of some of them have increased steadily during the 20th century and into the 21st, with CO2 rising from under 300 ppm to 400 ppm. A large part of the increase in all greenhouse gases is attributed to human sources, i.e. it is anthropogenic, hence the term ‘anthropogenic global warming’ (AGW).

Why is the increase in atmospheric carbon dioxide dangerous? A) The gas inhibits the escape of heat from Earth’s atmosphere. B) Carbon dioxide inhibits rainfall causing long droughts. C) The gas prevents plants from photosynthesizing. D) Carbon dioxide is highly toxic if inhaled.

Correct answer: A) The gas inhibits the escape of heat from Earth’s atmosphere.  

The earth temperature depends upon the balance between the incoming radiation from the sunlight and the energy that is reflected back to space. Carbon dioxide absorbs the heat sent to earth by the sun, it acts as an insulator of the earth and helps to keep the atmosphere warm and make suitable for life process.

But, when the concentration of carbon dioxide in the atmosphere is increased, it means more and more increase in the temperature of the planet and cause global warming and make the life difficult on the planet. As a result of that whole life on the earth would be in danger.

Name the layers of Earth’s atmosphere starting closest to the Earth’s surface and moving up. Which layer contains the ozone layer? Which layers get warmer as the altitude increases? Which layers get colder as the altitude increases?


The atmosphere is composed of five layers, namely troposphere, stratosphere, mesosphere, thermosphere and exosphere, with the layer closest to the surface being thicker than the ones above it.

The troposphere is the first layer above the surface and contains a portion of the Earth's atmosphere. This layer contains the ozone layer which is characterized by the ability to be able to absorb harmful rays from the Sun. Rock fragments burn up in the mesosphere.

The thermosphere is a layer where space shuttles orbit. The exosphere is characterized by the end of the atmosphere and its emergence into space.

The layers that get warmer as the altitude increases are the stratosphere, thermosphere and exosphere while the layers that get colder as the altitude increases are the troposphere and the mesosphere.
