Mechanical Weathering

Explanation:

Mechanical Weathering changes the chemical composition of rocks.

1. Chemical Weather- causes changes in both the composition and appearance of rocks. breakdown of rocks by chemical reaction. The process by which other chemicals combine with oxygen. Oxygen in the air or water can cause chemical weathering.

2. Index Contour- The difference in elevation between the highest and lowest points in the area on the map. ... They are usually mapped with small contour intervals. Index Contour. A darker, heavier contour line that is labeled with an elevation.

6. A. Surface material breaks down into smaller pieces.

9. breaks sediments into smaller pieces transports sediment to a new location works with deposition to carry away rocks.

Erosion is the carrying away of sediment by wind, water, ice, and other agents; the process by which sediments are obtained and transported

I'm sorry but i don't know #'s 3, 4, 5, 7, and 8 but i do hope these help you and i am truly happy to help you.

its erosion

Explanation:

ANSWER FORM EDGE 2020

Surely, It's erosion.

Erosion breaks the rocks down into halves.

Have a nice day

The correct answer for above statement is:1.chemical weatheringExplanation:

Chemical weathering is the weakening and consequent disintegration of rock by biochemical effects. These reactions involve oxidation, hydrolysis, and carbonation. These rules each form or dissolve minerals, therefore modifying the nature of the rock's crystal structure.

2.The correct answer for above statement is:contour intervalExplanation:

The elevation interval within neighboring contour lines, announced as the contour interval, is chosen to excellent show the overall configuration of the area. A map of a comparatively low area may have a contour period of 10 feet or less. Maps in isolated areas may have contour intervals of 100 feet or more.

3.The correct answer for above statement is:water drains quicklyExplanation:

Sand inside the soil is really tiny scraps of weathered rock. Sand is reasonably rough and loose so water is ready to percolate through it easily. While this is great for effluent, it is not good for planting plants because sandy soil will not retain water or nutrients.

4.The correct answer for above statement is:loess hillssand dunesExplanation:

Loess is an aeolian deposit created by the addition of wind-blown silt, typically in the 20–50-micrometer size range, twenty percent or fewer clay and the equilibrium equal shares sand and silt.Sand dunes are primarily hills of sand. They produce when the wind is blocked by a rock and it falls some of the sand as it hits the rock. Slowly the accumulated sand sculptures up to form larger dunes.

5.The correct answer for above statement is:particle with sharp endsExplanation:

According to the stokes law George Gabriel Stokes determined an invention, now known as Stokes' law, for the frictional force – also declared drag force exercised on spherical things with very small Reynolds amounts in a viscous fluid.

6.The correct answer for above statement is:Surface material breaks down into smaller pieces.Explanation:

Erosion is a normal manner which is normally made by rock and soil being released from the earth's surface at one place and passed to another. Erosion reduces the landscape by using down mountains, filling in valleys, and creating rivers emerge and die.

7.The correct answer for above statement is:They are spherical and three-dimensional.Explanation:

A globe is a three-dimensional, spherical, scale model of Earth (terrestrial globe or geographical globe) or different celestial bodies such as an asteroid or moon. While examples can be made of objects with uncertain or changing shapes, the term globe is used only for examples of objects that are generally spherical.

8.The correct answer for above statement is:to calculate an area’s contour intervalExplanation

Contour lines can be drawn for any mountain, but to clarify things, only lines for specific heights are drawn on a topographic map. These elevations are chosen to be equally spaced vertically. This vertical spacing is related to as the contour period.

9.The correct answer for above statement is:transports sediment to a new locationExplanation:

Erosion in earth geology relates to the movement of surface methods, like wind or water flow, which excludes the rock, soil, or suspended material from one location to another location of the Earth's crust. This natural appearance is a result of the dynamic motion of erosive factors, like ice, water, snow, plants, wind, animals, and humans.

either erosion or I think mechanical weathering

chemical weathering

Explanation:

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
