result‚ the mantle becomes less dense and will gradually rise closer to the lithosphere. The cooler‚ denser mantle then begins to subduct back down closer to the mantle thus replacing the rising‚ less dense mantle. This process of events creates a convection cycle throughout the mantle. This rotating movement causes the lithospheric plates to move. The significance of tectonic movements directly impacts Denali through the subduction process of the Pacific Plate underneath the North American Plate which

Each day over 40‚000 thunderstorms are taking place on earth. A thunderstorm is a form of weather characterized by the presence of lightning and its acoustic effect on the Earth’s atmosphere known as thunder. The meteorologically assigned cloud type associated with the thunderstorm is the cumulonimbus. Thunderstorms can generally form and develop in any geographic location‚ perhaps most frequently within areas located at mid-latitude when warm moist air collides with cooler air. They are the result

In Martin Luther King’s “I Have a Dream” speech‚ he stressed that now is the time to give African Americans true freedom‚ equality‚ and opportunity. This is still very relevant to African Americans today‚ even though it shouldn’t be. I say it shouldn’t be because now‚ for Mr. King was 52 years and five months ago. These problems have been going on for more than half a century after he professed his dream‚ and there has been little change since then. There is still discrimination towards blacks and

A force can do one of four things to an object: 1. Make it speed up - accelerate. 2. Make it slow down - decelerate. 3. Change its direction. 4. Change its shape. If something is doing one of these four things there must be net force acting upon it. Newton’s First Law ’Every body continues in a state of rest or uniform motion unless acted upon by an external force.’ Something without net force acting on it will either stay still or move at a constant speed in a straight line until
