Will marine food sources keep up with human population growth?
Answer:
That is a 50/50 chance of happening.
Explanation:
Why?
The human population is projected to reach 9200 million by 2050 (UN 2007), which is within estimates of the maximum carrying capacity of the planet (Cohen 1995). A fundamental question for science is whether it is possible to increase food production to meet the demands of a human population of that magnitude.

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.

the parent rock that was altered by metamorphism is called the protolith. what is the protolith of slate? group of answer choices coal any igneous rock gneiss sandstone
The parent rock that was altered by metamorphism is called the protolith. The protolith of slate is igneous rock.
The original, unaltered rock from which a certain metamorphic rock is created is known as a protolith.
For instance, shale or mudstone makes up the protolith of a slate. There are many different protoliths since metamorphic rocks can be created from any other non-metamorphic rock type. One of the main objectives of metamorphic geology is to identify a protolith. Protoliths are not really protoliths; they are non-metamorphic rocks. Sedimentary rocks, created from sediment, and igneous rocks, formed from magma, are the two categories of non-metamorphic rocks. A sedimentary rock's provenance is the place where the sediment that made it originated.

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.
