7. Which of the following causes seasons on Earth? (1 Point) the variation in proximity of the Earth to the sun at different times of the year the constant tilt of the Earth, combined with its orbit around the sun the distance between the Earth and the sun in winter versus in the summer the variation or wobble of Earth's tilt during the year 8. In the region of the Rocky mountains, imagine that one local variety of Ponderosa pine (Pinus ponderosa) predominantly occurs between 50000 and 80000 feet in elevation, where it can best tolerate temperatures and precipitation. If future climate change in this region causes the temperature to increase and rainfall to decrease, then which of the following changes might an ecologist predict about the variety' range (1 Point) that variety will occur at lower elevations that variety will occur at higher elevations that variety will occur at lower elevations and/or lower latitudes that variety will occur at higher elevations and/or higher latitudes 9. The mountain areas of western North America, north-facing slopes would be expected to (1 Point) receive more sunlight than similar southern exposures be warmer and drier than comparable southern-exposed slopes support biological communities similar to those found at lower elevations on similar south-facing slopes support biological communities similar to those found at higher elevations on similar south-facing slopes 10. Imagine some cosmic catastriphe jolts Eath so that its axis is perpendicular to the orbital plane between Earth and the sun. The most obvious effect of this change would be (1 Point) the elimination of tides an increase in the length of the year a decrease in temperature at the equator the elimination of seasonal variation 7.
