B) Use public transportation often
The solutions to environmental problems are “coordination of environmental efforts between sectors”, “enforcement of environmental regulations”, “sustainable land management practices”.
<u>Explanation:
</u>
The environmental problems in any region can be a threat to that region since it may affect their health to a greater extent. In order to eradicate any environmental problem in a region there must be a good coordination existing between sectors which will result in solving an environmental problem easily and quickly.
Strict enforcement of environmental regulation acts and policies also plays a major role in solving the environmental problems. Land management practices are those that combine the land management, water bio diversity and other resources in environment for meeting the needs of human beings.
This specific process is called frost weathering or cryofracturing. It is a situation when Water collects in small cracks in a rock, then freezes. and caused the rock to crack and break off in pieces.
<h3>What is frost weathering?</h3>
Frost weathering is physical weathering that involves freezing and thawing of waters in an area with extremely cold weather. When water freezes its size expands and damages the area.
Its best example is when water collects in small in a rock then freezes. The expansion of the water while frozen causes the rock to break into pieces.
Therefore the Forst weathering is from of physical weathering.

Great Famine, also called Irish Potato Famine, Great Irish Famine, or Famine of 1845–49, famine that occurred in Ireland in 1845–49 when the potato crop failed in successive years. The crop failures were caused by late blight, a disease that destroys both the leaves and the edible roots, or tubers, of the potato plant. As a direct consequence of the famine, Ireland's population fell from almost 8.4 million in 1844 to 6.6 million by 1851. About 1 million people died and perhaps 2 million more eventually emigrated from the country. Many who survived suffered from malnutrition. Additionally, because the financial burden for weathering the crisis was placed largely on Irish landowners, hundreds of thousands of tenant farmers and laborers unable to pay their rents were evicted by landlords unable to support them. Continuing emigration and low birth rates meant that by the 1920s Ireland's population was barely half of what it had been before the famine.
The heaviest elements settled in the Earth's center during the formation of Earth's lithosphere
<u>Explanation:</u>
Earth's lithosphere comprises the crust and the uppermost mantle, which form the strong and rigid external layer of the Earth.
The Earth, on the other hand, begins with a core of iron and radioactive materials such as uranium and plutonium, which deliver energy in the form of heat, within a process known as nuclear fission. It passed by a fusion stage - a "liquid-pasty" state - which provided that, due to gravity, the more solid materials dropped towards the center, while the smaller ones floated towards the crust, a process called planetary differentiation.
