Some of these landforms are the result of erosion. Other landforms form as water deposits the sediment it is eroding. Landforms Produced by Water What adjectives would you use to describe water? Water is responsible for most of the landforms found on the Earth’s crust. Some of these landforms are the result of erosion. Other landforms form as water deposits the sediment it is eroding. Some of the landforms created by water are the results of rivers, streams, and the water the flows under the ground. Landforms Produced by Water Rivers Streams and rivers form when water flows along the same path time and time again. Landforms Produced by Water Rivers Streams and rivers form when water flows along the same path time and time again. As the water moves, it erodes the underlying land to form a channel, or valley. Landforms Produced by Water Rivers Streams and rivers form when water flows along the same path time and time again. As the water moves, it erodes the underlying land to form a channel, or valley. The valley of a young river is very steep and is shaped like a capital V when viewed from the side. Landforms Produced by Water Rivers Streams and rivers form when water flows along the same path time and time again. As the water moves, it erodes the underlying land to form a channel, or valley. The valley of a young river is very steep and is shaped like a capital V when viewed from the side. Because water flows very quickly through young river valleys, it causes much erosion. Landforms Produced by Water Rivers As a river matures, its valley widens. Landforms Produced by Water Rivers As a river matures, its valley widens. At this stage, the flow of the water is more from side to side than it was when the river was younger. Landforms Produced by Water Rivers As a river matures, its valley widens. At this stage, the flow of the water is more from side to side than it was when the river was younger. This sideways movement causes a large, flat area called a floodplain to form on each side of the river’s channel. Landforms Produced by Water Rivers Floodplains are often marred with curves or bends in the river that are called meanders. Landforms Produced by Water Rivers Floodplains are often marred with curves or bends in the river that are called meanders. When a meander becomes totally cut off from the rest of the river, a landform called an oxbow lake forms. Landforms Produced by Water Rivers Often, long mound-like deposits of sand or gravel called bars form parallels to the flow of the water in a river channel. Landforms Produced by Water Rivers Often, long mound-like deposits of sand or gravel called bars form parallels to the flow of the water in a river channel. Crescent-shaped bars often form on the inside of a mature river bend. Landforms Produced by Water Rivers As rivers or streams empty into large bodies of water, a fan-shaped deposit called a delta often forms. Landforms Produced by Water Rivers As rivers or streams empty into large bodies of water, a fan-shaped deposit called a delta often forms. The coarse sediment grains drop close to the river’s mouth. Landforms Produced by Water Rivers As rivers or streams empty into large bodies of water, a fan-shaped deposit called a delta often forms. The coarse sediment grains drop close to the river’s mouth. The finer sediments drop farther from the mouth. Landforms Produced by Water Rivers Rivers that flow down mountain sides deposit sediment when the water reaches a broad, flat area. Landforms Produced by Water Rivers Rivers that flow down mountain sides deposit sediment when the water reaches a broad, flat area. Like deltas, these deposits are shaped like fans, but are called alluvial fans. Landforms Produced by Water Rivers Any water that is beneath Earth’s surface is called groundwater. Landforms Produced by Water Rivers Any water that is beneath Earth’s surface is called groundwater. Some groundwater is trapped in the pore spaces within rocks. Landforms Produced by Water Rivers Any water that is beneath Earth’s surface is called groundwater. Some groundwater is trapped in the pore spaces within rocks. Some of this water even flows like underground rivers. Landforms Produced by Water Rivers Any water that is beneath Earth’s surface is called groundwater. Some groundwater is trapped in the pore spaces within rocks. Some of this water even flows like underground rivers. At times groundwater dissolves rocks to form huge holes called cavers, or caves.

Some of this water even flows like underground rivers. At times groundwater dissolves rocks to form huge holes called cavers, or caves. Some caves are only a meter or so long and high. Landforms Produced by Water Ocean Waves and Currents Rivers and streams are not the only moving water the produces landforms. Landforms Produced by Water Ocean Waves and Currents Rivers and streams are not the only moving water the produces landforms. Ocean waves and currents constantly shape and reshape a shoreline. Landforms Produced by Water Ocean Waves and Currents Rivers and streams are not the only moving water the produces landforms. Ocean waves and currents constantly shape and reshape a shoreline. Waves along a rocky coast, for example, erode rocks to form nearly vertical landforms called sea cliffs.

Waves along a rocky coast, for example, erode rocks to form nearly vertical landforms called sea cliffs. Sea cliffs are often eroded to form flat, horizontal surfaces called platforms. Landforms Produced by Water Ocean Waves and Currents When waves erode some rocks along a coast but not others sea caves form. Landforms Produced by Water Ocean Waves and Currents When waves erode some rocks along a coast but not others sea caves form. If sea caves are eroded from both sides, sea arches are created. Landforms Produced by Water Ocean Waves and Currents When waves erode some rocks along a coast but not others sea caves form. If sea caves are eroded from both sides, sea arches are created. Sea arches eventually collapse as waves pound against them. Landforms Produced by Water Ocean Waves and Currents When waves erode some rocks along a coast but not others sea caves form. If sea caves are eroded from both sides, sea arches are created. Sea arches eventually collapse as waves pound against them. The rock towers left behind are known as sea stacks. Landforms Produced by Water Ocean Waves and Currents Waves also create and destroy beaches. Landforms Produced by Water Ocean Waves and Currents Waves also create and destroy beaches. Waves that crash on shore constantly move sand along the beach. Landforms Produced by Water Ocean Waves and Currents Waves also create and destroy beaches. Waves that crash on shore constantly move sand along the beach. During winter, large waves take sand away from the beach, causing the beach to shrink. Landforms Produced by Water Ocean Waves and Currents Waves also create and destroy beaches. Waves that crash on shore constantly move sand along the beach. During winter, large waves take sand away from the beach, causing the beach to shrink. The beach grows larger during the summer months when smaller waves add sand back to the beach. Landforms Produced by Water Ocean Waves and Currents Waves and currents flow onshore and erode or deposit sediment to change a coastline, producing various types of landforms. Landforms Produced by Water Ocean Waves and Currents Waves and currents flow onshore and erode or deposit sediment to change a coastline, producing various types of landforms. Spits are long ridges of sand that extend outward from a shore into the ocean. Landforms Produced by Water Ocean Waves and Currents Waves and currents flow onshore and erode or deposit sediment to change a coastline, producing various types of landforms. Spits are long ridges of sand that extend outward from a shore into the ocean. Barrier islands, such as those along much of the eastern shoreline of the United States, are deposits of sand that form parallel to the coast. Scripture Spotlight What does Isaiah 48:17-19 say about waves? Scripture Spotlight What does Isaiah 48:17-19 say about waves? Isaiah 48:17-19 includes the thought that if God’s people had paid attention to His word, they would have had peace like a river and righteousness like the waves of the sea.
