Why do angular sediments have a lower porosity?
Angular sediments have lower porosity compared to rounded sediments because angular grains have irregular shapes that leave less space between them. This results in a more compacted arrangement of grains, reducing the overall porosity of the sediment.
Which is a coarse-grained clastic rock that contains angular fragments?
Breccia is a clastic sedimentary rock with large angular fragments cemented in a finer matrix.
Why do sediments have angular or rounded fragments?
Angular sediments are usually young or "immature" sediments which have only recently been weathered from a source rock. They have not been exposed to corrosive fources long enough to become worn down. These sort of sediments are common in glacial areas or areas high in a river catchment near their original location.Rounded grains suggest extended periods of transport and mechanical weathering, which chip away the sharper edges of the immature sediments leaving them worn dow. a common example of this is a desert sand, which has been exposed to errosive forces for a long time, being blown around the desert, giving them a rounded appearance.Think of a broken piece of glass. In its "immature form, it has sharp edges and smooth faces. If you throw it in the ocean on a beach, and give it time, the surf and sand will weather it smooth, leaving you with nice smoth beach glass, a mature sediment.
Sediments derived primarily from the products of weathering on the continents are called?
terrigenous or continental sediments
They type of sedimentary rock that forms when sediments stick together?
The type of sedimentary rock that forms when sediments stick together is called "clastic sedimentary rock." These rocks are created from the compaction and cementation of loose particles like sand, silt, and clay. Examples include sandstone, shale, and conglomerate.

What characteristics of sediments would tell you that the sediments is texturally and compositionally mature or immature?
Texturally mature sediments are typically well-sorted, meaning they have a uniform grain size, and often exhibit rounded grains due to extensive weathering and transport. Compositionally mature sediments contain stable minerals, like quartz, and lack unstable minerals such as feldspar or mica. In contrast, immature sediments tend to be poorly sorted with a mix of grain sizes and angular shapes, and they often include a variety of minerals, indicating limited transport and weathering.
What one sedimentary process makes conglomerate and breccia rocks different?
Conglomerate rocks are formed from rounded particles, while breccia rocks are formed from angular particles. This difference in particle shape is due to the transportation and deposition processes that these sediments undergo before forming rocks.

What is a brief summary for the section angularity in the Earth science book?
when particles collide with each other and with other object in their path it happens when sediments is transported from its source to where it is deposited. these collision can cause the particles to change size and shape. angular and uneven rocks are when particles that have moved long distances from the source tends to be more rounder and smoother. the farther sediments travel from its source the finer and smoother the particles of sediments become.
What is the adjective of angle?
'Angular' , as in ' the angular corner'.
Angular momentum is a measure of?
angular momentum is the measure of angular motion in a body.
How can one determine the angular acceleration when provided with the angular velocity?
To determine the angular acceleration when given the angular velocity, you can use the formula: angular acceleration change in angular velocity / change in time. This formula calculates how quickly the angular velocity is changing over a specific period of time.
How do you calculate angular acceleration in a rotational motion system?
Angular acceleration in a rotational motion system is calculated by dividing the change in angular velocity by the time taken for that change to occur. The formula for angular acceleration is: angular acceleration (final angular velocity - initial angular velocity) / time.
Define angular impulse?
Angular impulse is defined as the rate-of-change of the angular acceleration.
How do you calculate angular momentum in a rotating system?
Angular momentum in a rotating system is calculated by multiplying the moment of inertia of the object by its angular velocity. The formula for angular momentum is L I, where L is the angular momentum, I is the moment of inertia, and is the angular velocity.
