Chapter 3 homework

Ch 3 section 1:
     1. Not all planets recieve the same ammount of direct sunlight at the same time. Areas that recieve large ammounts of direct sunlight have warmer temperatures that places that recieve little sunlight. This is why Earth's position in relation to the sun affect's Earth's temperatures.
     2. Global warming affect Earth’s water by making it evaporate from oceans more quickly and increase humidity and rainfall generally. Rapid evaporation from soil will cause land to dry out more quickly between rains. Also, the increase in CO2 gas in the atmosphere will cause Earth's greenhouse affect to trap more heat.

Creative Writing: I disagree and agree with the statement "“Global warming is a natural process and there is nothing we can do to affect the severity or effects of global warming on the environment.” Global warming is caused in part by human activites, such as the burning of coal, oil, and natural gases, however, we can affect its severity. We could do this by using up less of the Earth's natural resources.

Ch 3 section 2:
     1. The regular pattern of the sun's rays can be correlated with bands, or zones, of latitude to describe climate regions. At all latitudes, elivation influences climate because of the relationship between the elevation of a place and its temperature.
     2. Wind patterns play the role of distributing the sun's energy around the planet. Ocean currents play the role of warming or cooling the surface of the land they pass. Finally, the climate of places at the same latitude can be very different, depending on the presence or absence of physical features. Lakes and other large bodies of water affect the climate of more coastal regions, and mountain ranges produce an affect known as the rain shadow. The windward side of the mountain- the side facing the wind- gets most of the moisture in the form of precipitation, and the leeward side of the mountain- the side sot facing the wind- gets warmer and drier as they descend.

Creative Writing: The european climate could become colder and drier if the North Atlantic Current was weakened or shut down permanently.

Ch 3 section 3:
     1. Geographers classify the climate regions of the world by organizing them into tropical, dry, midaltitude, high altitude, and highland.
     2. Recurring phenomena influence climate patterns over time by changing it.  When humans burn fossil fuels, gas is released that mixes with the water vapor in the air. This could destroy forests and other natural landforms, which in turn changes the climate.

Creative Writing:  Huntington Beach is a coastal region and has cool summers, and cool, damp winters. It also has mixed forests, full of coniferous and deciduous trees.
