Sediment texture describes the physical characteristics of a deposit in this scenario.
<h3>What is Texture?</h3>
This is referred to the appearance of a substance based on properties such as size, shape etc.
Sediment texture therefore helps to define the physical features of a deposit which could be sandy soil.

Multiple-choice tests are scored by a computer.
Essays written for the College Composition exam are graded by two or more college English professors. The essay grade is combined with the multiple-choice score, and the result is reported as a scaled score.
A small number of colleges require optional essays for American Literature, Analyzing and Interpreting Literature, College Composition Modular, and English Literature, which are evaluated and graded by the colleges that require them. A copy of the essay and the score report of the multiple-choice section will be sent to your designated institutions.
Answer:
Death Valley’s crazy heats are caused by a combination of the lack of water, geography, and materials that make up the valley.
The average yearly rainfall in Death Valley is only 2 inches. This is less than many other deserts in the world, averaging around 10 inches of rain annually. This intense lack of water also creates a lack of plants in the area resulting in the expanses of sand in the valley open to constant heating by the sun.

Sea level in Death Valley
Driving into the valley you get to experience the geography of the environment, traveling from 1000 feet to 4000 feet above sea level and down to 100 feet below sea level. These mountain ranges you drive over top 4000 feet and surround the lowest point in the United States of 282 feet below sea level. This creates an interesting phenomenon of trapping the hot air within the valley.
Sand and rocks make up the valley floor which radiate a large amount of heat. However, because of the geography, this hot air cannot escape. Instead, the hot air rises along the valley walls, cools slightly and then falls back to the valley floor to be heated even more by the hot sand and low elevation air pressure. This concept of movement by heating and cooling is called convection and exists in many other life circumstances like the boiling of water or in a kitchen oven. Despite the movement of air and possibility of high winds, the winds do not do much to cool down the hikers in the valley because the wind is still very hot.
The heat can be so extreme that signs in the park advise turning off the air conditioning in certain areas to avoid overheating of cars, making the experience an even toastier one. Additionally, hiking is recommended only before 10am and with lots of water.
Despite the heat it is worth braving the heat to experience the truly unique views of Death Valley. This unique environment allows for rock formations, salt flats and expanses unlike anything else in the United States.
Explanation:
No product results in -1, hence δlmn is NOT a right triangle showing that lydia's assertion is incorrect
<h3>Perpendicular lines</h3>
In order to determine whether triangle lmn is right-angled, we need to determine the slope of lm, ln, and mn first as shown:
For the slope of lm:
For the slope of ln:
For the slope of mn:
- If any of the two lines is perpendicular, hence the triangle lmn is right-angled.
- To check, we will take the product of the slopes and see if it is equivalent to -1.
Product of slope lm and ln
Since no product results in -1, hence δlmn is NOT a right triangle showing that Lydia's assertion is incorrect
