A mineral property that is a description of how resistant a mineral is to being scratched is hardness.
What is hardness?The resistance to localized plastic deformation caused by mechanical indentation or abrasion is measured as hardness.Hardness varies by substance; for example, hard metals such as titanium and beryllium are harder than soft metals such as sodium and metallic tin, or wood and ordinary plastics. Macroscopic hardness is characterized by strong intermolecular interactions, but the behavior of solid materials under stress is complex; thus, there are three types of hardness measurements: scratch hardness, indentation hardness, and rebound hardness.Therefore, a mineral property that is a description of how resistant a mineral is to being scratched is hardness.

The island of Maui in the Hawaiian Island chain is 1.32 million years (1,320,000). Measure the distance from the center of the big island of Hawaii to Maui to determine the rate of movement of the Pacific Plate between the Hawaiian hotspot and Maui. Follow the same format for 2a, inserting the years in the correct spot. You need to measure the distance:
Rate of movement of Pacific Plate (i.e. speed) =
The Rate of movement of the Pacific Plate will be 37.87cm per year.
Underneath the Pacific Ocean is an oceanic tectonic plate known as the Pacific Plate. It is the largest tectonic plate at 103 million km2. The Farallon, Phoenix, and Izanagi Plate triple junction are where the plate initially formed 190 million years ago.
From the information given, the following can be deduced:
Distance = 500 km = 50000000cm
Time = 1.32 million years = 1320000 years.
Therefore, the rate of plate movement will be (i.e. speed) :
(speed) = Distance / Time

What is the natural rubber material used to obturate the pulpal canal after treatment is completed?
Gutta-percha is the natural rubber material used to obturate the pulpal canal after treatment is completed.
What is Gutta-percha?A durable plastic substance derived from the latex of many Malaysian trees of the sapodilla family (particularly Palaquium gutta), which resembles rubber but contains more resin and is used mostly as insulation and in dentistry as a permanent filler in root canals. Gutta-percha is a tree of the Sapotaceae family that belongs to the genus Palaquium. The name also alludes to the tree's hard, naturally biologically inert, robust, electrically nonconductive, thermoplastic latex, which is a polymer of isoprene that produces a rubber-like elastomer. Gutta-percha is a natural rubber material that is utilized to seal the pulpal canal following treatment. The term "gutta-percha" is derived from the plant's Malay name, getah, which translates as "latex." Sumatra was previously known as Percha or Perca.Therefore, gutta-percha is the natural rubber material used to obturate the pulpal canal after treatment is completed.

Which stage in thunderstorm formation is characterized by updrafts accompanied by downdrafts induced by falling precipitation?.
The stage of thunderstorm formation which is characterized by updrafts accompanied by downdrafts induced by falling precipitation is called "mature stage."
What is thunderstorm?Thunderstorms are ferocious, brief meteorological disturbances that are nearly always accompanied by lightning, thunder, thick clouds, significant amounts of rain or hail, with strong gusts of wind.
Some characteristics of thunderstorm are-
Layers of warmer, moist air travel in a strong updraft to cooler areas of the atmosphere, whereupon thunderstorms form. At that location, the updraft's moisture condenses to create imposing cumulus clouds and, subsequently, precipitation. Cooled air columns then descend to the ground and are met by powerful downpours and horizontal winds. In parallel, electrical charges build up on cloud molecules (water droplets with ice). When the electric charge that has collected is sufficiently high, lightning discharges happen. When lightning strikes, it instantly and intensely warms the surrounding air, creating shock waves that sound like thunderclaps and rolls. Occasionally, air vortices that are spinning and powerful enough just to create tornadoes are present with intense thunderstorms.To know more about ingredients to a thunderstorm, here

What would happen if water infultrated to the depths of the clay lens at point a:______.
Infiltration would happen if water infultrated to the depths of the clay lens at point .
Cavitation is the movement of water through the soil. Eventually, as water seeps into the deeper layers of the soil, it reaches aquifers, i.e. water below the surface. The upper surface of this aquifer is called the "groundwater".
Infiltration occurs when water seeps into the ground from the ground. It moves underground and moves between soil and rock. Part of the water will be absorbed by the roots to help the plant grow. The leaves of the plant will eventually release water into the air through the plant and out as waste.
The process by which water seeps into the ground to become groundwater is called groundwater recharge. The area on the surface where water infiltrates is called the recharge area. Groundwater can be recharged by rain in a number of ways: Rain seeps into where it falls and recharges aquifers from groundwater.

Stratosphere: it lies above the troposphere. It extends up to 50km above the ground. The ozone layer is present in the stratosphere which protects us from the UV rays of the sun. Mesosphere: it lies just above the stratosphere. The height of the mesosphere is around 85 km above the ground. The temperature gets really cold in this layer. Thermosphere: in this layer the temperature starts to increase again. It lies above the mesosphere and the satellites orbit the planet earth in this layer.
