turn helps us better understand earth! Why do we spend so much money on finding out what is surrounding us, when earth isn’t safe nor completely explored. This is what I don’t understand. In source A, David Livingston states that “the manned space exploration is absolutely worth the cost.” I do not entirely disagree with this statement, but when Livingston says “how to be a better steward of precious earth” that is when it aggravates me. As human beings of Earth, we have not explored the…

Gondwana eventually created the continents we know today, does not mean that these continents will stay the same forever. Eventually, there will be different arrangements in an extensive history of continental adjustment. Continents and landmasses on Earth are always moving in a state of slow motion. Also, at times, many continents come together as one. These supercontinents include Columbia, which is also known as Nuna, Rodinia, Pannotia,…

Landslides and mudslides are both characterized by a large amount of mud, rock, or other masses of Earth sliding down a slope, such as a cliff or a mountain. Santa Barbara, a city parallel to the Pacific Ocean and right along the Santa Ynez mountain range, has been victim of landslides in the past. A notable example is the 1995 La Conchita landslide…

What is global warming? a. Global warming is the increase in the temperature of the entire earth. i. As the temperature increases the atmosphere is being damaged by the increased levels of carbon dioxide (CO2) produced by the greenhouse effect. ii. The greenhouse effect is the trapping of the sun’s warmth in the planet’s lower atmosphere due to…

Wildfires are natural disturbances that shape landscapes and can alter aquatic ecosystems and communities. Wildfires can be followed closely by flood events that cause debris flows and scouring, potentially compounding effects on aquatic systems. In 2011, the Horseshoe 2 Fire of southeast Arizona burned over 90,000 hectares of forest and was followed by massive monsoonal rains. These rains triggered flood events that scoured creek beds within the range. In one stream within the affected…

Unfortunately, there is a misconception that wetlands are wastelands, despite their value to our environment, society and economy. Our wetlands are threatened by numerous activities. Global Warming Global warming has the potential to alter the structure and function of our wetlands. Sea level rise threatens to inundate many coastal wetlands, with little room to move inland because of coastal development. Warmer water from global warming will alter the species composition and contribute to…

The Six Great Extinctions Extinction is just another word used for the dying off of one species or of many species. Since the beginning of time there have been five mass extinction and then some smaller extinctions. Either big or small, they play a huge role in the evolution of the species around us. Whether they were a common ancestor, or a close relative to an organism, they still helped the organisms we know today evolve and adapt to the environment that we now share. During the extinction…

In the blog, “Life At Colony Camp: A blog” by Soledad Suarez, if the piece were told from multiple points of view, the reader’s understanding of this story would significantly change. For example, the reader’s understanding of the Colony Camp would change if the piece was told from another point of view. For instance, in the blog, “As I reflect on our time here at Colony Camp, I experience a swirl of emotions and realize I am much more excited than nervous. I feel strong and ready for almost…

number is 1 and it is apart of group number: 18. The group that Helium falls under is the Noble Gases. The element has an atomic number of 2, an atomic mass of 4 and is classified as a non-metal. It is the second most abundant element in the universe. Helium was discovered on the sun before it was found on the earth. In 1895, Pierre-Jules-César Janssen, a French astronomer and Norman Lockyer, an English astronomer both who discovered the element helium; found out about it while studying the…

Mars has an unforgiving and dangerous environment, which is why it’s not safe to send someone there. It’s not impossible to send someone to Mars, it’s that we’re not ready or prepared to send someone there yet. The program Mars One will send four unlucky people to Mars in the year 2022, and it would be a terrible idea to sign up. Many things could go wrong, including all of the low oxygen and cosmic radiation, running out of fuel and food, and the fact that Mars One is a one way trip!…
