Earth Sciences

Isn’t the Earth a beautiful and majestic place?

Every time you walk out of the door of you home you are met with a plethora of different components that make up our environment, and ultimately Earth science. Earth science is the study of the earth and all of its elements. It is a way of investigating the world around us through observation and experiment. Even though science has led to many discoveries, there is always something new to discover about the earth.


Several branches of science make up earth science including Geology which is the study of rocks, earthquakes, volcanoes and fossils. Meteorology is the study of the atmosphere and the weather. Another branch of earth science is mineralogy. It is the study of minerals and their location and mining. Oceanography is the study of waves, tides, currents, trenches and ocean life. Paleontology is the study of plant and animal fossils and Petrology is the study of the formation and structure of rocks and their chemical content.

Men living thousands of years ago once thought that there was a god in the sky who threw thunderbolts to the earth when they saw the flashes of lightening in the sky. The concept of a thunderstorm was beyond their understanding. As time passed, each generation gathered new information through the study of earth science and slowly the earth was beginning to be understood. To this day, the study of the earth continues.

Scientists still conduct experiments to find out answers to their questions about the earth. Science projects that deal with topics related to earth science are extremely interesting for viewers and fun for the young scientist who conduct them. Think about doing a project about erosion. This is a big problem today for our coasts. When a big storm comes along, a lot of the sand that makes up the beach is washed away. Scientists have come up with solutions over the years but the problem still exists. A great earth science project would be to conduct different experiments on how erosion happens and different things that may help to stop erosion. Since earth science deals with a lot of different branches of science, there a lot of different experiments that can be conducted and studied. You might want to demonstrate how a part of the earth is explained or studied. For instance your science project can demonstrate how wind speed is measured or how a wave is formed.

Another interesting science project related to earth science would be to create a project explaining how sedimentary rocks are formed. A great example of a sedimentary rock formation is the Grand Canyon in Arizona. The layers of rock that make up the canyon are millions of years old. Scientists still conduct experiments and have controversial discussions on how old these rock layers are. Wouldn’t it be fun to find these things out for yourself?

As long as people live on the earth, there will be earth science. Scientists will always want to answer new questions and prove the new theories that they come up with.

The Best Materials For Roof Repairs

Your roof needs immediate repair when it leaks or when a few shingles have come loose. You cannot afford to put it off or your entire roof could become compromised leading to a much more expensive problem. For most homeowners the biggest concern with a roof repair is the cost. If you notice a leak or you suspect one, you will want to know the types of roof materials suited to repairs.

If you have had your roof damaged following a storm, you can do a quick inspection of the damage by using a pair of binoculars to scan the surface. Do not climb up a ladder to look as that could be very dangerous following a storm.

They will know your local municipal codes which must be adhered to when replacing or repairing a roof. They can also recommend if the roof repair should be done with the same material or if it needs to be replaced altogether. In this instance, they can help you figure out the best material to choose for your budget.

Asphalt shingles are among the most common and long-lasting roofing materials available. These might need to be replaced altogether if you already have two layers of roofing on your home. But, they do resist many types of weather, they can last about 30 years and they do not warp in extreme temperature fluctuations.

Another common type of roofing material is metal. These usually come as recycled materials so they are safe for the environment. They are fireproof and lightweight yet also durable. An added bonus is that if you install this type of roof for your replacement or repair, you get to save money on energy bills every month.

Slate roofs are extremely durable and last about a century. However, they are heavy and very expensive. A great alternative is fake slate which can be made up of many different materials including rubber. Cedar shakes are another expensive material but they require proper cleanings or they can lose their stability and require immediate replacements.

Tile roofs are durable and protect a home against many different elements. They are highly resistant to fire. They take more time with repairs, but they are usually worth the wait.

Ask your local roofing contractor to inspect your roof and determine which repair materials are best for you. If you do need a whole replacement, you can decide on buying a whole new material so that you get more durability and more use from this important part of your home. Here is a list of Portland companies.

Don’t forget that installing an entirely new roof is a great way to increase your home’s exterior appearance and its value. If you cannot get by with a small repair, shop for a new roof material carefully, but understand that it should pay for itself in a few years.
