Answer questions 5-10 on your review sheet. Slide 26 26 4.6A Identify patterns of change such as in weather, metamorphosis and objects in the sky. Weather is the condition of the atmosphere at any given time. Weather includes air temperature, wind speed, humidity, and precipitation such as rain, snow, sleet, or hail. Changes in weather result from the movements of air masses. The leading edge of an air mass is called a front. Fronts can be classified as warm, cold, or stationary. Slide 27 27 4.6A Identify patterns of change such as in weather, metamorphosis and objects in the sky. A thunderstorm is a small, intense weather system. It brings strong winds, heavy rains, lightning, and thunder. They occur when warm, moist air encounters much cooler, dryer air. A hurricane is a large, low pressure system that spins. Hurricanes form over warm, tropical waters and reach wind speeds over 120 km/h. They can cause a great deal of damage when they move near or over land. A tornado is a violent, spinning column of air that moves in a narrow path over land. Tornadoes sometimes form in severe thunderstorms. Slide 28 28 4.11A Test properties of soils, including texture, capacity to retain water, and ability to support life. Soil is a mixture of minerals and materials from decayed animals and plants. The composition of the soil depends on what kind of rock it was made from. Slide 29 29 4.11A Test properties of soils, including texture, capacity to retain water, and ability to support life. The formation of soil begins when rock is weathered by wind, rain, and moving water. Weathering breaks rocks down into smaller and smaller pieces. As plants grow and die in the soil, their remains are broken down by bacteria and fungi, creating humus.

Answer questions 15-16 on the review sheet. Slide 41 41 5.6A Identify events and describe changes that occur on a regular basis such as in daily, weekly, lunar, and seasonal cycles. The reason for day and night is the rotation of the Earth. Earth rotates (SPINS) once on its axis every 24 hours. It is daylight on one side of the Earth, while the other side has night. Slide 42 42 5.6A Identify events and describe changes that occur on a regular basis such as in daily, weekly, lunar, and seasonal cycles. It takes 1 year or 365.25 days for the Earth to revolve (ORBIT) the sun. Earths movement around the sun is called its revolution. Since it takes the Earth 12 months (1 year, 365 days) to revolve around the sun, moving from Point A to Point B on the diagram would take 3 months (one- fourth of a year). Slide 43 43 5.6A Identify events and describe changes that occur on a regular basis such as in daily, weekly, lunar, and seasonal cycles. 4.6A Identify patterns of change such as in weather, metamorphosis, and objects in the sky. The moon has no light of its own. It simply reflects light from the sun. Since the moon is rotating on its axis AND revolving around the Earth, the part of the moon we see changes during each month. Slide 44 44 5.6A Identify events and describe changes that occur on a regular basis such as in daily, weekly, lunar, and seasonal cycles. 4.6A Identify patterns of change such as in weather, metamorphosis, and objects in the sky.
