Chapter 3, Section 1
1. Earth's rotation and its tilt cause changes in weather and climate around the world. This is beacause it depends on what areas of land recieve the suns light and at when they recieve it. Earth is in a perfect position to get the right amount of light and heat from the sun. If we were any closer or further away from the sun Earth might not be able to sustain the life we have on this planet today, it would either be too hot or too cold.
2. Global warming might affect the Earth's air by trapping heat because of our thick layer of carbon dioxide in the atmosphere. This would make the air much dryer and warmer that it is nowalso causing extreme weather patterns. It can affect the water by causing it to evaporate very quichly from oceans, rivers, and seas causing escalated rain and humidity. This quick evaporation may cause water to evaporate too much from the soil which will make the land dry out.

I disagree with this statement. Global warming is not a natural process, it is due to all the polution and build up of carbon dioxide in the atmosphere because of manmade processes like burning coal, oil, and other natural gas. Humans can decrease the severity and cause it to happen slower by maybe redusing the exposure of these gasses into the atmosphere and comming up with ways to do things naturally. We can use electric cars to burn less fuel and use safer "green" household products to reduce polution.
Chapter 3, Section 2
1. Latitude and elevaton make all the difference to climate. The higher latitude an area has the colder the climate will be because these areas are furter away from the equater. Land masses around the equater, tropic of capricorn, and tropic of cancer are usually the warmest. The suns light shines the most near the equater, therefore making them the warmest. Although nomatter the latitude, elevation always affects climate too. The higher the elevation, the the thinner the air is, and the thinner the air is, less heat is trapped causing it to be cooler.
2. Winds occur when sunlight heats the atmosphere unevenly. As warm air rises cool air then flows through to fill the space. Winds affect climate because they are what distributes the sun's energy around the Earth. It is the same with ocean currents. As the currents circulate they move cool water from the polar regions in towards the equater.
Creative Writing:
If someday the North Atlantic Current were to shutdown permanatly, there would be a lot of changes in western Europe. The land that is being cooled from this current would not be getting any cold water from the polar areas. This would cause the land to increase in heat and change the climate. There would be nothing cooling the area except wind patterns.
Chapter 3, Section 3
1. Geographers classify climate into five main categories: tropical, dry, midlatitude, high latitude, and highland. These areas are divided and classified based on the characteristics of its soils and natural vegitation.
2. Reoccuring phenomenons can change climate over time because of things like acid rain, smog, ice ages, and global warming. These things can change the enviornment causing heat to be trapped. This can change the climate as time passes.
Creative Writing:
Huntington Beach has a midlatitude climate, but more specificly a mediterranean climate. We have a variable weather patterns and seasonal changes which make for a variety of natural vegetation. We experience cool summers and cool damp winters. Our rainfall supports the growth of mixed forests of both coniferous and deciduous trees.

Chapter 2 Homework
Chapter 2 Section 1
1. Earth is composed of 4 geological areas. First is the hydrosphere which is all the bodies of water on earth(i.e. oceans, lakes, and rivers). There is also the lithosphere, the Earth's crust which is made up of land. The atmosphere is a layer of gases that extend beyond the planets surfaces and the biosphere is the part of the earth that supports all living organisms.
2. Mount Everest is the highest point on earth and is the greatest distance from sealevel. It is 29,028 feet above sealevel.
Creative Writing: I disagree because when things like meteroids and comets come into earths atmosphere they do leave long term effects on Earth. Even though most meteroids burn up before they hit Earth, some will hit. When they do it can cause much damage and destruction to the land by leaving huge craters and flattening and burning what is there when it hits.
Chapter 2 Section 2
1. Most of the movement of the surface of the Earth's surface is due to what happens in the deep layers inside the Earth. Some things that trigger changes in the enviornment come from Earth's inner layers like volcanos for example. When land masses slide apart and move past eachohter they create things like volcanos which causes magma to be pushed up from the mantle layer. This is what causes riges to be formed on the surface.
2. Internal forces of change effect the way landmasses on Earth look and are shaped. For example they cause mountains, folds in rock, faults in the Earth's crust, and they effect the way the plates spread and move, earthquakes, and volcanic eruptions. Although external forces of change come from places other that the surface of Earth itself and cause things like the breaking down of rocks by weathering and erosion of land either from wind, glaciers, and water.
Creative Writing: Over the past 225 million years North America has changed signifigantly. Originally scientists think that all the land masses must have once fit together like a puzzle but gradually drifted apart due to internal forces. Plates slowly move about 1 inch each year, so the land masses are obviously more spread out then they were in the past. Also since there had been less movement long ago there would have been less mountain ranges and volcanos and large features on the surface of Earth becase these things are all caused by the movement of plates.

Chapter 1 Homework
Chapter 1, Section 1
1. When choosing a map projection cartographers need to decide what the purpose of theyre map will be. Any two dementional map projection will be distorted in some way because the round shape of the earth is very difficult to project onto a flat surface. For this reason different maps are better in different circumstances depending on what the map will be used for. If they are making a map for travel and navigation it would need to be more accurate in size than one to show size.
2. Mountains and rivers(physical), boundaries and capitals(political), and roads and highways(human-made) can all be shown on an urban-area map.
Creative Writing:
It would be useful to know the population of the area, locations of surronding neighborhoods, other schools in the area, economic activities nearby, roads, and housing development.
Chapter 1, Section 2
1. The major branches of geography are physical geography and human Geography. Physical geography consists of the Earth's physical features like, climate, land, water, plants, and animal life in terms of their relationships to one another and to humans. Human geography also called cultural geography, studies mainly political, economic, social, and cultural factors like, population growth, urban development, and economic productin and consumption.
2. By looking at maps made in the past geographers are able to watch how living things have developed in the past and they also allow us to predict change so we can build a better future. it is also used by many people to plan and make decisions.

Huntington Beach is a nice seaside city in Orange County. It is known for its long 8.5 mile beach, and has a mediterranian climate. Huntington Beach contains many areas of protected wildlife within it. As early developers were beginning to expand and build Huntington Beach, oil was discovered and the community began to change because people did not want to build houses on areas with oil. It gradually developed from farms and oil wells to a community of home buisinesses and schools as more and more people moved to the city.
