Earth's outer core is liquid MOSTLY because of its temperature Some large rivers, such as the MS River, form a delta where they meet the ocean, with land forming that extends into the sea. The formation of the delta is the result of erosion upstream where the flow is energetic and _____ where the flow is less rapid. deposition 00:34 01:18 Which type of rock is formed when sand, silt, clay, gravel, and cobbles become physically cemented or chemically fused together into hard rock? Sedimentary Which force caused the hydrogen, helium, and lithium formed from the big bang to collect and form stars, planets, and other objects, as well as to form the elements other than hydrogen making up these objects? Gravity Which process generates the energy that stars emit? Fusion of hydrogen or other small nuclei to form larger nuclei Which effect is NOT caused by gravity? A planet's atmosphere retaining thermal energy Which property characterizes the outer planets compared to the inner planets? Gaseous and less dense When it is winter in New York City, which season is it in New Zealand, which is in Earth's Southern Hemisphere? Summer The hottest part of Earth's interior is its ____. inner core A meander in a river develops primarily from _____. erosion on the side of the river where flow is faster and deposition on the opposite side. Many cycles of water getting into a rock and expanding by freezing have produced large cracks. This is an example of __________. physical weathering The dust bowl occurred during the 1930s in the Midwest when a drought killed most of the crops in the region. Which agent of erosion was most important in causing the loss of the loose, dry soil left behind? Wind 00:01 01:18 Which statement about glaciers is the MOST accurate? Glaciers flow and reshape their surroundings by erosion, weathering, and deposition. Which conditions are needed for a sand dune to form? Lots of loose sand, an obstacle, wind What is an example of a mineral? Calcite (composed of calcium carbonate) A geologist notices that four layers of rock are stacked directly on top of each other. The geologist labels the top layer as #1 and the bottom layer as #4. Which layer is the oldest? #4 Which statement about fossils is correct? The fossil record is incomplete because most organisms simply die and decay. What does the term Pangaea refer to? The landmass that all of Earth's continents were once joined together to form At which location are volcanoes and strong earthquakes likely? At boundaries between converging tectonic plates Which kind of plate boundary occurs where the plates slide past each other? Transform Which layer of Earth's atmosphere has the lowest density? Exosphere In which layer of Earth's atmosphere do storms and other weather phenomena occur? Troposphere The atmospheric pressure meteorologists refer to in speaking of weather is __________. the force from the air divided by the area on which it acts correct The trade winds are prevailing winds that blow over long distances. Their paths curve to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. Which process causes their paths to curve? Earth spinning on its axis Which mechanism causes the motion of air that leads to convection cells? Heated air being pushed up and colder air sinking A hydroelectric power plan converts the energy from flowing water in rivers into electric power. Water exists on Earth in all three states of matter as it makes its way through the water cycle. What is the main driving force for the water cycle? The sun by causing evaporation Which states of matter of water can be involved in the hydrologic cycle? All three- solid, liquid, and gas Which natural body or area of water accounts for MOST of Earth's water? Oceans What is groundwater? Water that soaks into the soil What is the cause of a hurricane? Warm ocean water producing an upflow of warm, moist air In winter, the prevailing winds from west to east pass over the relatively warm waters of the Great Lakes. At Watertown, NY, on the eastern edge of Lake Ontario, the land rises, and the winds force warm, moist air upward. Which kind of winter weather would this make more likely in Watertown when the wind from the west is strong and the air is cold? Snowstorms What happens in an area where there is an anticyclone? The air pressure is higher, and sinking cold air reduces cloud cover. When a cold front moves into an area with warmer air, what are the likely consequences? Warm air being pushed upward, which may produce precipitation
