Answer:

d) Pioneer species have large numbers of offspring, and climax communities contain species that have small numbers of offspring.

Explanation:

A pioneer species is the first species to inhabit a bare area of land. Many times, this bare land is covered with rocks, so the plants that first inhabit the area are important because their roots break up the rocky land to access nutrients beneath them. Pioneer species usually have the following characteristics:

Tolerable of harsh living conditions

Seedy plants that germinate easily

Small seeds so they can be dispersed by the wind easily

Have a short life cycle

Reproduce asexually

Once these pioneer plant species take root, they are important for the growth of the ecosystem because they provide homes for smaller animals and insects. They also trap moisture in the soil so other plants can grow in the new ecosystem as well. One of the most important factors in the development of a pioneer community is the amount of wind an area receives because the wind is responsible for carrying the seeds of different plants to these barren locations.

Answer:

The answer is "Its three countries of North America were also situated between both the Tropical of Cancer as well as the Arctic Circle primarily throughout the North Temperate Climate".

Explanation:

In the given question the incorrect choice is missing, which can be defined as follows:

The above given choice is wrong because North America is also a member of both the tropics region. In general, North America was made up of 3 nations: Mexico, Canada, and the United States.
Mexico was its lowest, which is also Latin America's largest state and has several parts of all its territories throughout the temperate region. North America is thus the economically very relevant diaspora of America.

Deals with the movement that shape earths crust

andriy [413]

Answer:

Plate tectonics

Plate tectonics is the scientific theory explaining the movement of the earth's crust. It is widely accepted by scientists today. Recall that both continental landmasses and the ocean floor are part of the earth's crust, and that the crust is broken into individual pieces called tectonic plates

Describe the four processes of magma differentiation.

andrezito [222]

Answer:

the four processes of magma differentiation are starting with Fractional crystallization , Assimilation , Replenishment and Magma mixing.

Explanation:

Magma differentiation -

It is also called igneous differentiation , is a kind of combination term for the various processes involved in the chemical change by which magmas undergoes bulk changes during cooling , emplacement , partial melting process or eruption .

The process involved has been called the FARM process , i.e , starting with Fractional crystallization , Assimilation , Replenishment and Magma mixing.

Fractional crystallization of igneous rocks

This is the most important geochemical process that is working inside the Earth's crust and the mantle . This process of segregation and removal from the melt of the mineral precipitates , that can change the composition of the melt .

The process is complex in context as it varies by a wide variety of phenomena , that are , temperature , composition and the pressure .

Assimilation -

This process explains the mafic magmas as it get rise from the crust and the felsification of the ultramafic . The assumption involved in this process is that the hot primitive melt intrudes into a cooler and the felsic crust will melt crust and get mixed with the resulting melt , which in turns alters the composition of primitive magma .

Replenishment -

During the process of the cooling of the melt , the results are limited so as to produce a solid body of intrusive rock , which is homogeneous in nature and which has uniform composition and mineralogy . This is due to -

The fresh magma can change the melt's composition ,and the fresh magma can destabilizes the minerals , even change in temperature can lead to rapid crystallization .

Magma mixing -

The composition in between of two end - member magma is achived by combining two magma's and forming a single composition.

This is a common process in the volcanic magma chambers , that are a open - system chambers , and magma under goes various processs of assimilation , fractional crystallization , and partial melt extraction and are replenished . Even this process is operated deep in the crust and is one of the primary mechanism for the formation of the rocks like monzonite and andesite .

Rate of cooling impact crystal size -

Crystals are formed by the cooling of the magma ,

There are two types of cooling possible , rapid cooling and slow cooling , both can lead to different types of crystal .

If the magma is cooled quickly , i.e. , rapid cooling , the crystals will not have time to form , hence are small in size ,

And in case the magma is cooled slowly , the crystals will have ample amount to time to grow in size , and , hence will form larger crystals .

If the igneous rock has large crystals , then it indicates that the rock was formed deep inside the earth , because deep inside the earth , it is warmer .

These are called intrusive rocks, and have a phaneritic texture .

If the igneous rock has small crystals , then it is formed by rapid cooling , near the Earth's surface . These are called extrusive rocks and have an aphanitic texture .
