The answer is true it can be traced to one particular reason.
Answer:
More efficient use of agricultural land can boost crop yields and meet growing global demand for food. Smallholders have a vital role to play, both because they produce much of the world's food and because they represent a large share of the world's poor and food insecure.

Answer:
The rocks are comprised of cracks and fractures in between the sediments and mineral grains that have the capacity to store fluid in them. This fluid is generally the water that contains various types of dissolved ions. These fluids in the rocks are very much important because the chemical reactions that take place include the change in mineral from one type to another new type. This can highly increase the amount of dissolved ions that are dissolved and transported by the water. This alteration of rock that occurs chemically due to these fluid refers to the process which is commonly known as the metasomatism. Whereas, the rock alters mineralogically due to the increasing temperature and pressure condition, that changes the grade of rocks.
This is how metamorphism alters the rock chemically in comparison to mineralogically.
Answer:
A. higher temperatures
C. penguins losing their natural habitat
D. rising sea levels
Explanation:
The greenhouse effect is caused by the trapping of more solar radiation on the surface of the earth than the normal level by certain gases. These gases are called greenhouse gases. Trapping solar radiation on the earth leads to increase in the earth's surface temperature. Polar ice begins to melt and more water is added to the ocean which can lead to rising sea levels and flooding of coastal cities. Ice caps will significantly diminish. As we know penguins are known to inhabit cold climates around the southern pole, if the polar ice in this region melts, their habitat becomes threatened.
