Activity 50.1 What Factors Determine Climate?
The map on the next page shows a hypothetical continent on Earth. Assume that biomes and climates on this continent are produced by the same factors that produce biomes and climates on Earth’s real continents. Use this map to answer the questions in this activity. Where needed, draw the required features directly on the map.
1. On the map of the hypothetical continent, indicate the location(s) of these types of biomes: Use the information in Figures 50.10, 50.18, and 50.19 of Biology, 7th edition, to answer these questions.
a. Tropical rainforest(s)In general, tropical rainforests lie between the equator and about 25° north and south latitudes, where the annual mean precipitation exceeds 150 cm and the annual mean temperature exceeds about 23°C.
b. Temperate coastal desert(s)Temperate coastal deserts tend to lie between 25° and 45° north and south latitudes, where the general direction of the trade winds is away from the coast and the annual mean precipitation is less than 40 cm.
c. Temperate deciduous forest(s)Temperate deciduous forests tend to lie between 30° and 60° north and south latitudes, where the annual mean precipitation exceeds 102 cm and the annual mean temperature exceeds about 11°C.
To do this, draw approximate boundary lines to delimit each biome type, and then label each delimited area with the type of biome it contains.
2. Atmospheric circulation is driven primarily by differential heating of Earth’s surface. More heat is delivered near the equator than near the poles. This seems to explain the northward and southward flows of air. What introduces the eastward and westward components into air movement? (Hint: Review Figure 50.10, Global Air Circulation and Precipitation Patterns and Global Wind Patterns, and its associated text in Biology, 7th edition.)As indicated in Figure 50.10, “as Earth rotates on its axis, land near the equator moves faster than that at the poles, deflecting the winds from the vertical paths” introduced by differential heating. This deflection creates more easterly flow patterns between the equator and 30° north and south latitudes and more westerly flow patterns between 30° and 60° north and south latitudes.
A hypothetical continent3. Use your understanding of global air circulation and wind patterns to draw arrows on the map of the hypothetical continent indicating:
a. The direction of prevailing winds at points W1, W2, and W3b. The direction of flow of surface currents in the ocean at points O1, O2, and O3
(Hint: Note on the map in Figure 50.10 that surface currents in the ocean follow the major wind systems at the surface.)
4. Are the surface winds at the given points warming or cooling as they move? Explain.
Point on the mapAre the winds warming or cooling as they move?
Explanationa. X1
The winds are warming.The general wind pattern in this area is from the south west (westerlies). These winds tend to pick up moisture as they move from 30° to 60° N latitude.b. X2
The winds in this region tend to be cooling. This region tends to be under the influence of the cooling easterly winds. These winds tend to pick up moisture as they flow from 30° to 0° N latitude.c. X3
The winds are warming. The general wind pattern in this region is westerly. These winds tend to pick up moisture as they flow from 30° to 60° S latitude.
5. What biomes or vegetation types would most likely be found at the given points? (Assume all are at sea level or low altitudes.)
Point on the mapMost likely type of biome or vegetation
A
This region would most likely contain coniferous forest
B
This region would most likely be a temperate grassland which will graduate into temperate deciduous forest as it moves east.
C
This could be a region of chapparal which would graduate into tropical forest as one moves south
D
This is most likely a region of tropical rainforest.

I have the same assignment rn witht he graph but i only have 4 points plotted and connected by lines am i doing it wrong plzzz???
The air temperature would drop quickly compared to the soil because the difference between solid and gas. But the ground will stay cooler longer than the air because it contains it better than the air.
