To review:
The climate changes that occur on moving from the equator towards the poles, and the two aspects of weather that determine the type of biome in any location.
Introduction:
There is a reduction in temperature, as we move from the equator, toward the poles. The type of biome depends on rainfall and temperature.
Explanation of Solution
The Earth being a globe has a curved surface. The equator is the part of the earth that is closest to the sun and the poles are the furthest away from the sun.
The concentration of the sun’s rays is highest near the equator. As we move away from the equator and toward the poles, the solar energy is spread over a larger area, and the rays of the sun travel a longer distance through the atmosphere. This reduces the amount of heat that reaches the surface of the earth towards the poles, resulting in reduced temperatures as we move away from the equator, and towards the poles.
The type of terrestrial biome is determined by the average temperature and average precipitation in the area, and whether they are constant or seasonal.
There is a reduction in temperature when moving from the equator toward the poles. The two aspects of weather that determine the type of biome in a location are the average temperature and average precipitation, and how they change seasonally.

- It is known that not only the biotic factors are responsible in maintaining and sustaining the Earth’s properties, but also the abiotic factors. Of all the climatic factors given, which do you think is the most significant that affects all factors? Why?arrow_forwardThe graph illustrates the temperature and precipitation conditions in various terrestrial biomes. a) Based on the information in the graph, describe the air temperature range for a boreal forest. (b) Based on the information in the graph, identify the major grassland present within 20 degrees north and south of the equator.arrow_forwardChoose a specific biome between the marine, freshwater, or any terrestrial biome. Discuss the types of plants and animals in that biome. Describe the climate and any non-living components (such as water, rocks, soil) of the biome. Where can the biome be found? What biogeochemical cycles occur in this biome? Are there any reservoirs for the nutrients? Where can the nutrients be found and what processes do they go through as they transition to a different reservoir? Describe at least two of the biogeochemical cycles and the nutrients and minerals that move through them in your chosen biome.arrow_forward
- Which biome is characterized by hot, dry summers and cold, harsh winters, contains a thick topsoil ideal for plant and crop growth, and large grazing animals?arrow_forwardWhich type of biome is characterized by low precipitation, very cold winters, the abundant presence of small shrubs and trees in addition to animals such as caribou, wolves and foxes?arrow_forwardHumid continental and humid subtropical climates both feature deciduous forest biomes. A major difference between these biomes is a) winter temperatures drop below freezing in the subtropical climate. b) trees grow taller in the continental region. c) continental climates are more humid. d) trees may not lose their leaves in winter in the subtropicsarrow_forward
- What is the micro-climate zone of North Carolina?arrow_forwardWhat impacts would be expected to water supplies or other hydrologic features such groundwater table, oceans, etc., if the climate zone was to change in Texas?arrow_forwardIf the climate zone was to change in Texas, what zone do you think it will change to, and why? If not, why not?arrow_forward
- If the climate zone was to change in Texas, how might changes in drylands elsewhere impact far away regions?arrow_forwardWhere would you expect to find the most photosynthesis in an ocean biome? a. aphotic zone b. abyssal zone c. benthic realm d. intertidal zonearrow_forwardIndicate what is the most likely biome to occur in each of the locations below.arrow_forward
