What is a sentence using the word sediment?
"The sediment deposited by the Nile River has formed a wide delta at its mouth.""Sediment can eventually fill up shallow mountain lakes until they become meadows."(metaphorically) "That bottom drawer is stuffed with the sediment of my school days."(humorously) "The new geologist on our team just showed me a lovely sediment."
What are some sedimentary rocks that are essential to human health or that are used to make life more convenient?
limestone- deposited on the bottom of lakes and shallow sea bedsrock salt- make salt
What is a brief summary for the section stratification in the Earth space science book?
stratification is the layering of sedimentary rocks. stratification occurs when the conditions of sediments deposition change. the conditions may vary when there is a change in sediment type or of depositional environment. an area that was once a beach to become as shallow ocean is cause by a rise in sea level. stratified layers, or beds, vary in thickness depending on the length of time during which sediments is deposited. beds that has no internal structure is called massive bed.
From what rock is sandstone formed?
Sandstone is formed of layers of eroded rock grains deposited in shallow seas. Under immense pressure, the grains eventually become sandstone. Sandstone comes in many colors. Red sandstone is colored by iron oxide.
Why are deltas formed?
Basic geologic erosion. It rains in the mountains and the water runs downhill until it reaches the ocean, it carries with it boulders, rocks, gravel, sand, soil, plants, debris and trees in varying amounts dependent on the force of its flow.
Which rock was most likely formed from pebble sized sediment deposited in shallow water at an ocean shoreline?
conglomerate
How are landforms constantly being changed by water and soil deposits?
Sediment from upriver is being deposited by slow, shallow waters :) Goodluck Study Islanders <3

The is a shallow extension of the continent that extends beyond the shoreline?
Contenental Shelf.
Is a shallow extension of the continent that extends beyond the shoreline.?
Contenental Shelf.
What is the shallow extension of the continent that extends beyond the shoreline called?
The shallow extension of the continent that extends beyond the shoreline is called a continental shelf. It is the submerged part of a continent that extends from the shoreline to a drop-off point called the shelf break.
What is the term for the part of a continent that extends beyond the shoreline beneath relatievely shallow seawater?
The term for the part of a continent that extends beyond the shoreline beneath relatively shallow seawater is the continental shelf. It is an underwater extension of the continent that slopes gently from the shore to the ocean depths.
What is the salt-tolerant trees growing in shallow marine sediment or estuaries?
Smal ones..
What is the process called when deep water waves enter shallow water and the wave slows down and rotates toward being parallel with the shoreline?
refraction
What occurs where continental slope levels off and sediment accumulates?
Continental rise is what occurs where continental slope levels off and sediment accumulates. Continental rise can be shallow or deep and can occur at any level.
How does a longshore change a beach?
longshore currents are common at any beach that is exposed to breaking surf. A longshore current is an ocean current that moves parallel to shore. It is caused by large swells sweeping into the shoreline at an angle and pushing water down the length of the beach in one direction. Longsshore currents usually extend from the shallow waters inside the breaking waves to breaking waves on the outside. They vary depending on the size, strength, and direction of the approaching swell, and the length of the beach. The more prominent the swell size and direction, and the longer and straighter the beach is, the more powerful and swift the long-shore current will be. They are responsible for many rescues along the coast by sweeping swimmers and surfers down the beach into a variety of hazards. They also have a large inpact on the shorelineA shoreline is not static. As waves appoach shore and "feel the bottom", water piles up and breakers form (see "Waves"). Primarily these waves, breaking at an angle to the shoreline, are what generate a "longshore current" that parallels the shore. Importantly, the longshore current not only moves water in the surf zone, it also moves sediment parallel to the shoreline. Figure 1 illustrates that the direction of longshore current is a function of the angle of wave appoach. For example, if the waves appoach the shoreline from the south, longshore current moves from south to north.But longshore current and the resulting transport of sediment is only one of the dynamic processes that constantly alter the shoreline. As waves repeatedly hit the shore, water moves onto the beach and then retreats in a continuous cycle. However, the waves are not all that moves on the shoreline. In fact, the sediment on the shore is also always on the move. Great energy is expended on the beach as waves crash against the shoreline. This energy allows the water to transport sediment. The grains are lifted as the waves in the swash zone move onto the beach, and then the grains are deposited again as the water retreats. As long as the waves hit the shoreline "straight on" (i.e., the wave crests are parallel to the shoreline), the sand grains will be picked up and redeposited in the same general area. In this case, no real net movement of sand occurs in the swash zone. However, waves generally do not form parallel to the shoreline, and thus, usually approach the shore at an angle. Consequently, beach sand will have a net movement up or down the beach, depending on the direction of incoming waves. This net movement of the beach sand is known as beach drift.Figure 2 illustrates how beach drift operates. Notice on the diagram the angle at which the waves hit the beach. The water moves onto the beach close to the same angle. Recall that sand grains are transported as the waves move onto the beach. Therefore, the sand grains are being carried in the same direction that the waves are moving. However, when the water retreats, due to gravity it goes straight back perpendicular to the shoreline and not back in the opposite direction from which it came. Since grains are redeposited as the water retreats, the grains are actually deposited further down the beach or down longshore current. Hence, the net overall movement of sand is down current. Also, notice on the diagram that at a given point on the beach, the sediment that has moved down shore is replaced by sediment from further up shore, as long as sediment is available there. The net movement of sediment in Figure 2 is to the south because the waves are hitting the shore from the north. If the waves hit the beach from the south, the net movement of sand will be to the north. Net beach sediment movement, or beach drift, can change back and forth with shifts in wave direction. However, along any particular shoreline one direction for incoming waves usually dominates resulting in a preferential net movement of sediment. Sediment transported by beach drift as well as that moved by longshore current together are called littoral transport.Why are longshore currents dangerous?Long-shore currents can sweep swimmers and surfers into rip currents, piers, jetties, and other hazardous areas. In many cases, the long-shore current is strong enough to prevent swimmers from being able to keep their feet on the bottom, making it difficult to return to shore.
What is kettle lakes?
A kettle lake is a shallow, sediment-filled body of water formed by retreating glaciers or draining flood-waters.
