because of the pH levels of the ocean is becoming more acidic‚ causing negative impacts on the structure of the shells that are made out of calcium carbonate. Furthermore‚ everywhere on Earth‚ ice and glaciers have been significantly shrinking from the Arctic‚ Alps‚ Himalayas and Alaska‚ glaciers have been retreating at a very fast rate.

Snowball earth is when the Earth was covered by ice and snow from pole to pole for long periods of time in the past. The average temperature on the surface was about -50° and at the equator it was about -20°‚ which is roughly the temperature of Antarctica today. This is because the solar radiation from the Sun is reflected back into space due to the icy surface of the Earth. The oceans play a major role on the temperature fluctuation associated with day and night and because the oceans have a layer

Landforms that have been Residual Landforms Valleys are flat areas between hills and mountains and are caused due to the actions of glaciers and rivers over millions of years. Valleys are divided into two kinds depending on their shape viz. V shaped valleys and U shaped valleys. V-shaped valleys are formed by the flowing rivers and Ushaped valleys are formed due to glaciers. A canyon is an erosional landform made by a river. Sea cliffs have been the result of the erosion of waves along the shore

Have you ever wondered about how or when the temperature started rising on the earth? Well‚ let’s just get straight to the point. I’m talking about climate change. It may not seem like an important topic but it is. It’s an immensely important topic. My goal today is to tell you about climate change and how it all began… All of this began in the 1800’s when the “Industrial Revolution” took place. When this happened‚ people started to make goods in factories‚ rather than making them by hand and because

One major component of environmental degradation is the depletion of the resource of fresh water on Earth. Approximately only 2.5% of all of the water on Earth is fresh water‚ with the rest being salt water. 69% of the fresh water is frozen in ice caps located on Antarctica and Greenland‚ so only 30% of the 2.5% of fresh water is available for consumption.[3] Fresh water is an exceptionally important resource‚ since life on Earth is ultimately dependent on it. Water transports nutrients and chemicals

the increase in natural disasters. Gore continues throughout the book to show the alarming effects that climate change is having on our world. Many photo comparisons of glaciers are used to show rising temperatures throughout the world. Gore uses computer generated simulations of rising sea levels‚ due to melting ice caps and glaciers‚ which provide a harsh glimpse into the possible future. Using a large variety of pictures and graphs Gore simplifies the complex scientific data into an easily comprehensible

Colonizing the Red Planet As humans we are very curious. We have explored and conquered all around Planet Earth. It’s only been a matter of time before we move onto bigger and better things. Mars may seem like it is too far away or too complicated to try and accomplish‚ but with the technology changing every day we are closer than ever to reach the red planet. Colonizing Mars can happen if we get water‚ learn how to grow food‚ obtain oxygen‚ and get the materials needed survive. Mars‚ otherwise know

is a moving glacier. Building this would cost more than $700‚000 (not including the cost for electricity and supplies). That would make a sum of about $3‚000‚000 for when it is first built and and about $2‚300‚000 for all the supplies and electricity. That probably does not even include the cost of shipping. which would add about $50‚000 every time a load of stuff is shipped there.
