Landforms - Weathering, Erosion and Deposition

Join Arjun, Aiden, and Rohan on an adventurous journey to the mysterious river valley shown above! In this valley, there are loose rocks resting on a solid rock layer. Can the flowing water carve the valley deeper over time?

• Yes, water can make the valley deeper by breaking off pieces of rock from the solid rock layer of the valley and by carrying loose rocks away from the valley.

• No, valleys do not get deeper.

• Yes, water can make the valley deeper by carrying loose rocks away from the valley, but water cannot break off pieces of rock from the solid rock layer of the valley.

• No, valleys can get deeper, but water cannot make them deeper.

Marvin visited an old library in the city. The outside of the library was decorated with many statues. Over time, the features of the statues had become rounded and less detailed. What MOST LIKELY caused this change?

• Deposition of dirt filling the letters

• Sedimentation of the stone

• Radiation from the sun

• Weathering of the stone

Abigail, Ethan, and Benjamin are on a quest to discover how rocks transform over time! They learn that long-term exposure to different environments leads to weathering, decomposition, and the creation of soils and sediments. Can you help them figure out in which climate chemical weathering will occur at a faster rate?

• Chemical weathering occurs faster in cool, humid climates.

• Chemical weathering occurs faster in warm, dry climates.

• Chemical weathering occurs faster in warm, humid climates.

• Chemical weathering occurs faster in cool, dry climates.

Join Henry, Mia, and Jackson on an exciting adventure exploring how erosion, transportation, and deposition shape our planet! Can you help them identify which number in the diagram represents a landform created by the deposition of eroded sediment?

• 1

• 2

• 3

• 4

Join Grace, Abigail, and Arjun on an adventurous journey to discover how the Earth is constantly changing! They learn that physical and chemical weathering are key players in soil formation. Can you help them identify which scenario is an example of chemical weathering?

• In Alaska, rocks are broken due to continuous freezing and thawing of water sitting in cracks.

• Beautiful and strange rocks, shaped by blowing sand, dot the Western United States landscape.

• For a rock to become a metamorphic rock, it must be heated and extreme pressure applied.

• Sinkholes are formed in central Florida as seeping water dissolves underground limestone rocks.

Imagine Avery and Rohan are on an adventurous hike through the Grand Canyon. They come across a mysterious bracket indicating missing rock layers. What do you think happened to those rocks?

• The layers of rock were eroded by the force of the Colorado River.

• The layers of rock were eroded by chemical weathering caused by acid rain.

• The layers of rock were eroded by the strong winds whipping through the canyon.

• The layers of rock were broken apart by physical weathering caused by tree roots then blown away by the wind.

South Florida is surrounded by salt water. The need for fresh drinking water has increased as the population has increased. Only 10% of our water comes from surface waters, the other 90% is pumped up from ground water sources. Where do residents of South Florida get most of their drinking water?

• deltas

• sinkholes

• lakes

• aquifers

Hey explorers! Imagine you're on a thrilling adventure with Oliver, Evelyn, and Aria in the heart of Florida's mysterious peninsula. The land beneath your feet is made of fascinating carbonate rock, like limestone and dolostone, covered by layers of sand and clay. These rocks are like nature's secret water reservoirs! But wait, through a magical slow chemical process, these rocks can dissolve. Can you guess which of the following landforms is created by this enchanting chemical weathering of carbonate rock?

• dunes

• rivers

• sinkholes

• mountains

Florida is frequently impacted by hurricanes and tropical storms. Imagine Harper and Jackson living near Florida’s coasts, trying to protect their homes and businesses with sandbags. They even build their homes above ground! But did you know there's a natural superhero landform that helps protect the coastlines and inland areas from floods and storm surges? Which statement correctly identifies this natural protector of the coast?

• Sinkholes decrease the chance for flooding by providing a place for excess water to go.

• Dunes provide protection from erosion caused by water.

• Rivers prevent flooding by preventing ocean water from moving inland.

• Mountains create a natural barrier to prevent erosion by wind.
