This chapter also uses Google Earth and contains some useful tips for novice users of the tool.
This diagram shows how precipitation is affected by the ocean and a mountain range.
This creates a “rain shadow.”. % This allows them to explore the relationship between biomes, climate, and topography. Precipitation increases moisture. The cactus plant on the right stores water in its stout, barrel-shaped stems. For example, in biomes with arid climates, plants may have special tissues for storing water (see Figure below). Global temperatures vary with the angle at which the sun's rays strike the different parts of the Earth's curved surface. How well these needs are met in a given location depends on the growing season and soil quality, both of which are determined mainly by climate. This lab requires a live Internet connection and Google Earth.

Students who are interested in acquiring more detailed maps of climate classifications may wish to visit this site: World Map of Climate Classifications. They choose one biome to research and become a biome expert for the class. 1. Therefore, cold climates with low precipitation may not be as dry as warm climates with the same amount of precipitation. Most of us are generally aware that the earth spins about its axis which includes the north and south pole. The Relationship Between Climate And One Or More Biomes Essay Sample. For example, there is a global belt of dry air masses and low precipitation at about 30° N and 30° S latitude. They examine maps and diagrams of biomes and climate patterns and consider the threats that changing climatic patterns present to existing biomes.
Temperature falls from the equator to the poles. Because climate determines plant growth, it also influences the number and variety of other organisms in a terrestrial biome. They produce concentrated urine, thus reducing the amount of water lost from the body. In Part B: If you do not have much experience with installing, navigating, and adding data to Google Earth, the lab will provide you with the information you need in order to practice and be prepared to support your students.
The differences in these biomes can be traced to differences in climate and where they are located in relation to the Equator. One biome which is part of the cold zone of the Earth where the latitude of the sun is from 60-90° is Tundra. Some schools may not have sufficient band-width or computers to run Google Earth, check your connections before trying this lab with students. If you look at the two pictures in Figure below, you will see very few similarities. A useful hands-on supplement to these labs would be world maps and globes. (10 marks). Climate is the average weather in an area over a long period of time. 4. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739.
Midway between the poles the earth bulges to its greatest extent and this is called the equator. What is climate? The kangaroo rat has very efficient kidneys.
And it is these abiotic factors that help determine the nature of a biome.
Register now! Temperate climates usually have the best soil for plant growth. (Part A can be done as homework.).
The air is dry when it reaches the leeward side of the mountain range, so there is little precipitation there. Take time to explore the maps on this page before sharing them with students.
This is apparent from the desert and rainforest biomes pictured in Figure above.
The desert animals pictured in Figure below also have adaptations for a dry climate. The Relationship Between Biomes and Ecosytems. Moist air from the ocean rises up over the mountain range. While the exact nature of the world’s biomes is a matter of some debate, they … For example, land near the ocean may have cooler summers and warmer winters than land farther inland.
If you have already been verified by the EarthLabs project, you will be taken directly to the file download page. Climate is classified based on atmospheric temperature and precipitation whereas a biome is classified primarily based on uniform types of vegetation. Weather refers to the conditions of the atmosphere from day to day. Alternately, this lab can be adapted and completed offline.

The following items are suggestions for inclusion in optional printed student notebooks. The picture on the left shows a desert in Africa. Why might it be an adaptation in an Arctic biome? A recent report from NASA JPL Climate Change May Bring Big Ecosystem Changes predicts that nearly 40 percent of land-based ecosystems will change from one community type to another by the year 2100 due to climate change. Climate can determine what biome is present, but a biome typically does not control or influence the climate in the same way. Plants are the major producers in terrestrial biomes. In this case, follow the printing and other instructions included in the PowerPoint. This file is only accessible to verified educators. However, other factors besides latitude may also influence temperature.
Describe the relationship between climate and biodiversity. In terms of moisture, climates can be classified as arid (dry), semi-arid, humid (wet), or semi-humid.

2. The global pattern of precipitation is influenced by movements of air masses. Have questions or comments?
In Part A: Students are introduced to the concept of the biome and the relationship between climate and biome. Please update your bookmarks accordingly. Although there are some similarities between a climate and a biome, there are also significant differences. They include tropical, temperate, and arctic zones (see Figure below).
In biomes with cold climates, plants may adapt by becoming dormant during the coldest part of the year. In Part B: Students download a Google Earth (KMZ) file which depicts Earth's major biomes. These include the following. To download one of the PDF or Word files below, right-click (control-click on a Mac) the link and choose ". Terrestrial biomes include tundras, temperate forests and grasslands, chaparral, temperate and tropical deserts, and tropical forests and grasslands.
Thick fur and a layer of blubber keep polar bears warm in their Arctic ecosystem.
Biodiversity generally increases from the poles to the equator. This is how the polar bears in Figure below stay warm.
Organisms evolve adaptations that help them survive in the climate of the biome where they live. Teachers may also choose to use the PPT file as a hands-on or assessment-type activity.
