Additionally, plants can house animals or provide prey animals with cover and camouflage to prevent them from being over-hunted. They also help create a more sustainable ecosystem. The presence of plants moderates the temperature and mitigates the effects of the wind and sun. The plants in the rainforest keep the rainfall patterns in balance with the rest of the earth's ecosystem ("The Biology of Plants," Missouri Botanical Gardens, 2009).
Even when plants are not directly consumed for food, they can help sustain human beings. Plants hold the soil together and guard against erosion. Plant compost acts as fertilizer for the soil. Plants can be used as medicine in the form of herbs and other medicinal plant derivatives, or as products in the form of rubber, burlap, and cotton. Plants were and are the first source of warmth -- wood is necessary to heat an old-fashioned stove and to build a campfire.
Without plants, the world as we know it is virtually inconceivable. For humans to live in a world without...
Earth Like Solar Planets Throughout the course of human history, astronomers have wondered about the possibility of finding life beyond the solar system. In the last 20 years, there has been more of an emphasis on identifying other earth like celestial bodies that are orbiting distance stars. This has been taking place through the launch of various orbital telescopes such as: Kepler. Monitoring over 150 thousand stars, Kepler is identifying earth
Life in Media Scientific Method http://www.youtube.com/watch?v=t7IUFdtZNXI&feature=related Although this is a video from the children's educational television program Sesame Street and thus designed for younger viewers, it can nonetheless prove a useful tool to those who are struggling with the processes that go into the scientific method. It also shows how important it is to make a hypothesis, but to be willing to change that hypothesis when to results of the experiment proves that
Continental tropical (cT) air masses are hot, dry, unstable at low levels and generally stable aloft (upper-level ridge); they originate in northern Mexico. Continental polar (cP) or continental arctic (cA) air masses are cold, dry, and stable originating over northern Canada and Alaska as a result of radiational cooling. (Oklahoma Climatological Survey, 2004)" The greenhouse effect has been in the news for the last several decades especially with the resulting
Earth hour will soon be in its sixth year. We are celebrating this event by becoming involved in the environmental movement. The hospitality industry has a special part to play in keeping the earth clean and habitable. After all, tourism and travel are some of the most common of human experiences. What is sustainability? What I mean to say is that sustainability is a way of life. It is not just recycling,
Earth Liberation Front (ELF) This is a case study on Earth Liberation Front (ELF), which is an extremist group emerged to protect the Mother Nature. ELF's origin, structure, leadership, motivations, and goals have been included as the primary elements of analysis in the case study. These aspects have come under analysis to provide an understanding about the group. Since this group is also considered as one of the terrorist groups
IX. Teacher presentation The teacher's presentation in inquiry-based learning must be one that presents questions to the students. This can be best achieved through an interesting presentation that requires students to actively and fully participate in that which is being presented by the teacher. Capturing the classroom attention in this activity may be easily accomplished through filling a basket or box with oddities relating to earth science and to one-by-one pull
