Module 2: Landforms
The hydrologic or water cycle is an important topic in geology that is tied to the weather and the formation of landforms. It is the stages of water on Earth as it transforms itself from liquid to gas to solid or liquid again (American Water Works Association, 2002). Discussed below are the hydrologic cycle and two different examples of it on Earth. One example is of Panama, which is a tropical climate. The other is of the Mojave Desert in California, which is a desert climate. These two very different climates demonstrate the hydrologic cycle in practical terms.
Water has three stages—liquid, gas and solid. Water on Earth can be liquid as rain, streams, or oceans. It can be a solid like hail, ice or snow. It can be a gas like vapor, steam or clouds. As described by the Department of Atmospheric Sciences (2010), the hydrologic cycle is the process of water changing from liquid to gas to solid. The energy of the sun drives the changes to water. When water is heated up, it evaporates, turning into a gas to form steam or vapor. The water vapor rises with warm air that when meets cooler air, condenses to form clouds. These clouds and water vapor can be transported around the world. Precipitation is when water falls to Earth, in warmer temperatures as liquid and in temperatures, as a solid. On Earth, precipitation can evaporate again or infiltrate the Earth to become groundwater. As ground water it can collect in oceans, rivers or on snowy mountaintops and glaciers. It can also be released back into the atmosphere via transpiration, when water evaporates off soil, trees. When water evaporates, the cycle starts again.

There are numerous stages that take place simultaneously in the hydrologic cycle and this includes evaporation. This is when the water alters from a liquid state into a gas. The damp air from the water rises into the atmosphere and when it cools, the vapor condenses and shapes into clouds. But those billows are not the only form the vapors make; it can also materialize as dew, fog and mist, which blanket the Earth, characteristically on a rainy or humid day. Evaporation takes place when water changes from a liquid state into a gaseous state, and ascents out of the pores of the earth and into the atmosphere as a vapor (“How”). While evaporation is taking place, condensation is also occurring. When the temperature in the air plunges, the clouds become heavy and as a result they relieve themselves of the extra weight, which is called precipitation. This produces rain, hail, snow and sleet, conditioned upon the temperate. As the precipitation falls, it enters the surface of the ground and percolates into the soil, which is called infiltration. The more porous the land is, the more the infiltration can take place. However, the ground cannot hold all of that water and floods. The excess rainfall, which is also called runoff that has not been absorbed makes its way into bodies of water, such as small ponds, rivers, lakes and parts of the ocean (“Summary”).
For example, then, drought is difficult to define in modern standards, it is typically classified as a shortage of water, usually associated with a deficit of rainfall. That is, drought occurs when the demand or use for water exceeds the current supply of water. It follows, then, the Colorado river drought does not solely affect one area, it’s grandeur has affected the whole southwestern United States. Additionally, the Colorado River Basin Water Management: Evaluating and Adjusting to Hydroclimatic provides information on the meager volume of rain fall. In theory, then, combined with increased temperatures from global warming, and a deficient of rainfall both circumstances have had a descending effect on most surrounding

The hydrologic cycle is a process that moves water throughout the Earth’s environment. “In terms of water, the earth is a closed system, so water isn’t added or removed from earth; it’s simply transformed, transported, and recycled” (Spooner, 2013). This process, driven by energy provided by the sun, cycles water in a never-ending cycle between the oceans, sky and land. The process begins with the sun causing evaporation of surface waters of the oceans. The vaporized water droplets attach themselves to dust particles and form clouds. In a relative short amount of time, the water vapor transforms into precipitation and falls in to Earth as rain, snow or other form of precipitation.
Physical characteristics vary on every location of this planet. In order to understand this planet, an assessment of different environmental aspects needs to occur to understand these variations. The purpose of this lab report is to evaluate the similarities and differences between three locations: Sacramento, CA; Austin, TX; and Augusta, ME. In order to thoroughly examine these similarities and differences, an examination will be made on Earth-sun relationships, water balance budgets, climate patterns, vegetation, as well as landform development. These similarities and differences will be found by utilizing different methods and deriving data and conclusions empirically. All three of the cities focused on in this lab report in very different locations and therefore, it is expected that the concluded data will reveal many differences in the themes mentioned above.
The ecosystem I have chosen is tropical rainforest. In the following paragraphs, I am going to firstly introduced the structure of tropical rainforest in brief, with the second part of the plant ecology and last the diversity within this ecosystem.
The biodiversity of this particular biome is vast and rapidly growing. One of the main reasons that there are so many species and animals living within this biome is due to the constant warm weather. It also supplies an almost 100% chance of water and food for the animals within. Small animals, including monkeys, birds, snakes, rodents, frogs and lizards are most common in tropical rainforests. Most of these animals and some insects rema...
One of the largest geographic physical structures in the United States is the Colorado River. Human activity and its interaction with this great river have an interesting history. The resources provided by the river have been used by humans, and caused conflict for human populations as well. One of these conflicts is water distribution, and the effects drought conditions have played in this distribution throughout the southwestern region. Major cities such as Las Vegas, Los Angeles, San Diego, and other communities in the southwest depend on the river. It provides water for over 20 million people, irrigation for 2 million acres of land, four thousand megawatts of hydroelectric energy, and over twenty million annual visitors for recreation purposes. Also, once in Mexico, the river provides water to irrigate half a million acres of farmland, and municipal and industrial water for 2 million people living in this delta region. The river distributes its flow from lakes and canals along its journey as well. Due to climate change, human demand, natural forces like evaporation and human-induced climate change this water supply is in conflict. Also, a recent change that began in March of 2014 will bring a temporary water surge to the delta of the Colorado River for the first time in many years to help restore this region, and it’s possible it could reach the Sea of Cortez once again.
The Yasuni National Park possesses very diverse rainforest which significantly impact how the ecosystem functions; yet the the processes of disturbance and succession greatly affect them ("Yasuni National Park, Ecuador", "Ecuador Yasuni ITT Trust Fund" ). Just one hectare of the park contains more species of trees and bushes than all of North America ("Foreseeable Impacts of Oil Industry Activity in Yasuní")! There are a staggering 1762 species of trees and shrubs that have been identified in Yasuni, and approximately 400 of them are inherent to the region (“Foreseeable”). Hundreds of the plants in the previously untouchable zones have not even been classified or studied in depth (“Foreseeable”). The park is also paradise to a multitude of animal...
Rainforests once covered 14% of the worlds land surface, however now it only covers a mere 6%. It is estimated that all rainforests could be consumed in less than 40 years. Trees are becoming more needed and used everyday. We need them cut down for many reasons such as paper and timber, while also needing them ‘untouched’ for other reasons like oxygen, we have to ask ourselves, which is more important? At the current rate, most of the rainforests are being cut down for resources like paper and timber, but less importance is being placed on main resources like oxygen.
Evaporation goes through a physical change because the liquid(s) get evaporated into the atmosphere and turn into a gas called water vapor. Next, it gets turned back into a liquid and comes back down to the ground as rain. This process is called the water cycle and it's a physical change because it can be changed into a new substance but can be changed back to its original substance. This information came from what I already knew from previous science classes.
