The correct answer is option D.
Dating a mineral within a metamorphic rock gives the age when the rock cooled below the closure temperatures of that mineral.
The method to date a mineral by using radioactive isotopes within a metamorphic rock to determine its age is called radiometric dating.
In general, minerals are found in organic matter such as wood, shells and bones, and rocks. Radioactive isotopes are found in minerals. The comparison between the parent and daughter isotopes can be used to determine the age of the mineral.
Only igneous rocks can be dated radio-metrically due to their single date of origin. However, both metamorphic and sedimentary rocks can not be dated.

What are minerals?
A mineral is an element or chemical compound that has formed as a result of geological processes and is often crystalline in nature. Examples include calcite, quartz, and feldspar minerals.
The chemical composition and atomic structure of minerals are distinctive. Numerous physical characteristics of minerals, including as hardness, lustre, streak, and cleavage, can be used to quickly identify them. For instance, the mineral quartz is quite hard and not as readily scratched as the mineral talc, which is quite soft and easily scratched.
Ore on the other hand, is a naturally occurring rock or silt that has precious minerals in it that may be extracted, processed, and sold for a profit. These minerals are usually metals.

what happens to sediments as they are transported (moved) further away from their source? select one: a. they become better sorted b. they become larger c. they become more angular
Whenever dregs are conveyed to the sea, these residue are modified and moved by disintegration processes.Through the effects of erosion and the remobilization of sediments, storm activities, in particular, have the potential to influence local patterns of sea level.
The transportation process typically leaves behind the coarser sediment. As a result, fine-grained sediment is typically found further from its source than coarse sediment. The manner in which sediment was transported and deposited is determined by clues it leaves behind.
When sediment moves from one location to another, what happens to it?
Through erosion, sediment moves from one location to another. The transportation and removal of rock or soil is known as erosion. Sediment can be moved by erosion through wind, ice, or water. Sediment, such as gravel or pebbles, can be washed downstream by water from a creek into a river and eventually to the delta of that river.

In 1991, the ecozone was home to about 2.5 million people, accounting for 9% of Canada's population and 6% of its urban population. In contrast to most ecozones, rural regions have a higher population density than cities.
The urban population is now 49%, which is much lower than the national average of 76%. With 320 000 people in 1991, Halifax is the biggest metropolitan area. Small fishing villages and resource-dependent settlements nestled along beaches are more prevalent than major metropolitan areas.

Storms that move northward along the eastern shore of north America during winter may produce heavy snowfalls by combining cold arctic air with warm, moist air coming in from the ocean. These storms are known as nor Easters.
Nor Easters are formed in North America when a cold air front and warm air front coincide with each other over the ocean forming a low-pressure system.
In this low-pressure area, clouds are produced that are gradually developed into a storm-like condition leading to nor Easters storms that move along the eastern shore in a northward direction during the cold weather season.
For example, a cold front originates from Canada and slides over the Atlantic ocean off to the eastward shore of the United States resulting in nor Easter storms.

How is coastal erosion affected by human activity?
The coastal erosion caused by storm waves is frequently made worse as civilization uses the coast more and interrupts its supply of sand by building cities, harbors, dams, flood control projects, and navigational structures.

describe the major differences between soil horizons that form in a temperate climate (like michigan) and those that form in a desert environment (like arizona).
Desert soil don't have much organic stuff because there isn't much vegetation, and the harsh heat quickly breaks down any organic material that is present.
The temperature and rainfall in temperate soils are adequate but not excessive, and the vegetation is acclimated to these moderate circumstances.
The soils in temperate climates are somewhat similar to excellent soils since they are less impacted by the climate extremes, such as the desert soil. The world's population is fed in large part because to temperate soils. The temperature and rainfall in temperate soils are adequate but not excessive, and the plant there is adapted to these mild conditions.
Desert soil have extremely little organic material, which is due in part to the lack of vegetation and in part to the scorching sun's fast breakdown of any organic material.
