Answer Questions #51-100 on your scantron DUE- Tomorrow by 8 AM ILS Question Which setup below would require the least force to lift a 100-gram mass a distance of 10 centimeters? ILS Question The diagram below shows stages in the development of a certain landscape. When did erosion become the most dominant process in the development of the landscape shown in stage 4? (1) at stage 1 (2) at stage 2 (3) between stages 2 and 3 (4) between stages 3 and 4 ILS Question The diagram below shows a cross section of rock layers in Earth’s crust. The forces shown in the diagram caused the rock layers to (1) fault (2) fold (3) form (4) expand ILS Question Several tomato plants are grown indoors next to a sunny window. The plants receive water and fertilizer and remain on the windowsill. What will most likely happen? (1) Most of the leaves on the window side will wilt and die. (2) The roots of the plants will grow upward from the soil. (3) Water droplets will collect on the leaves facing away from the window. (4) The stem will bend toward the window ILS Question The table below shows the symptoms of some diseases that are caused by bacteria. Which two diseases listed in the table affect the digestive system? (1) botulism and typhoid fever (2) botulism and pneumonia (3) tetanus and pneumonia (4) tetanus and typhoid fever ILS Question Which situation is the best example of ecological succession? (1) An organism survives a difficult winter. (2) The populations in an area remain the same. (3) One species replaces another species in an ecosystem. (4) Each of several species uses the same amount of resources. What is weather? Local or short term changes in temperature, rainfall, wind, cloud cover What is climate? The average weather conditions over a large geographic area that extends over a long period of time. How is the amount of rainfall affected by the mountain? How does altitude (elevation) affect temperature? The higher the altitude (elevation), the cooler the temperature. How do ocean currents affect temperature? Ocean currents can moderate (cool or warm) nearby coastal landmasses How does latitude affect the amount of solar radiation (direct sunlight)? As latitude increases, there is a decrease of solar radiation. How does latitude affect temperature? As latitude increases, there is a decrease in temperature. Describe where the air mass is formed & its characteristics. Maritime Formed over water Wet weather Continental. Formed over land Dry weather Polar Formed over northern latitudes Cold weather Tropical Formed over southern latitudes Warm weather ILS Questions Which term refers to the atmospheric conditions that prevail from season to season and year to year at a certain location? (1) Weather (2) climate (3) equilibrium (4) ecosystem Weather forecasts are more accurate today than in the past due to (1) global warming (2) air-quality control (3) plate tectonics (4) use of images from space ILS Questions The map shows the origin of a maritime tropical air mass. The arrow shows the general track of this air mass. New York State is labeled NY. Which temperature and moisture conditions are associated with this air mass? (1) cold and dry (2) warm and humid (3) cold and humid (4) warm and dry Which factor has the greatest influence on the direction of the air-mass track? (1) upper air currents (2) ocean currents (3) sea breezes (4) mountain barriers ILS Question The map below shows the total rainfall, in inches, for parts of New York State, Vermont, and New Hampshire over one year. The numbered dark lines connect locations with the same amount of total rainfall. State boundaries are indicated by What was the probable amount of rainfall, in inches, for Waterbury, Vermont, for that year? Describe the type of weather that is expected with a High pressure system? Nice clear weather Describe the type of weather associated with a Low pressure system? Unstable Wet weather Describe the weather a person would experience during the passing of a warm front? 1. Cool weather 2. Long period of rain 3. Warm front line passes 4. Warm weather Describe the weather a person would experience during the passing of a cold front? 1. Warm weather 2. Cold front line passes 3. Heavy rains & storms for a short period of time 4. Cool weather ILS Question The arrows in the diagram below show the circulation of air on a sunny day. The air circulation shown is caused by (1) both hot air and cool air sinking (2) both hot air and cool air rising (3) hot air sinking and cool air rising (4) hot air rising and cool air sinking ILS Questions The map shows a low-pressure system (L) over New York State in July. Describe one weather condition that was most likely produced along the fronts as this low-pressure system moved across New York State in July. Explain why this low-pressure system causes the temperature to be warmer in Syracuse than in Rochester.
