You have been enjoying warm weather when the weather station shows a map modeling an air mass moving toward your area. Look at the weather map. It has a row of blue triangles to represent the front where a cold air mass is moving toward a warm air mass. When the air masses meet, _________.
the cold front will push the warm air upwards and form clouds.

Horseshoe Falls, the largest sec(on of Niagara Falls, carries water from the Niagara River to Lake Ontario, in between the United States and Canada. The top rim of Horseshoe Falls has been slowly changing since it was first mapped in the late 1600s. This diagram shows the top rim of Horseshoe Falls viewed from above. The dotted lines represent the locations of the top rim when it was measured in the past. 11. Using evidence in the diagram, what claim can you make about how Earth’s systems interact to change the Horseshoe Falls landform?
A. Water moving across the geosphere sinks down into the rock, causing the river to become shallower. B. Water moving across the geosphere fills in the holes that were already there, but the rocks do not move.
C. Water moving across the geosphere slowly weathers and erodes the rim of the waterfall, causing it to change shape.
D. Water moving across the biosphere carries sediment that builds up on the edge of the waterfall, causing the hydrosphere to move in a new direction.
C. Water moving across the geosphere slowly weathers and erodes the rim of the waterfall, causing it to change shape.

The prevailing winds in the United States generally move from west to east. They also can dip farther north or south, bringing changes in temperature and weather conditions. The map shows the path of the prevailing wind called the “jet stream” as it dips over the United States during a typical winter. What effect do you predict the prevailing wind would have if its path shifted farther north during the winter months?
More parts of the United States will be warmer and wetter than usual.

Elaine visits the beach with her family. Elaine’s mother warns her not to swallow the water because there is salt in it. Elaine wonders how this compares to the water she uses at home. She develops a model to show how much salt water and fresh water cover Earth. Her model is shown here. How can Elaine improve her model so it is more accurate?
Draw the fresh water section smaller and the salt water section larger.

Which explanation BEST describes the changes observed in the Horseshoe Falls landform since the 1600s?
A. The rim of the waterfall has gotten narrower over time.
B. The rim of the waterfall has not changed much since the 1600s.
C. The rim of the waterfall has moved backward, or upstream, over time.
D. The rim of the waterfall has moved forward, or downstream, over time.
C. The rim of the waterfall has moved backward, or upstream, over time.

You want to model the interaction of the hydrosphere and the atmosphere to form ocean currents. With the help of an adult, you position a fan to blow air across the surface of a bathtub of water. As the air moves over the water, you notice the water level in the tub is lower near the fan and higher at the other end of the tub. What conclusion can you make based on your observations?
- Surface currents on the water cause wind in the atmosphere to move.
- Surface currents on the water move in the opposite direction of wind currents.
- Wind currents cause surface currents on the water to circulate with deep water.
- Wind currents cause surface currents on the water to move in the same direction.
4. Wind currents cause surface currents on the water to move in the same direction.
