Answer:
b. They distort scale and landmass shape.
Explanation:
Maps are an attempt to represent regions as faithfully as possible. But there is an obvious difficulty in representing curved or three-dimensional objects, such as the earth, on a flat, two-dimensional surface.
So distortions always occur, that is, some parts of the map will not correspond exactly to what is being represented. It's like opening a ball and trying to stretch it to make it flat like a sheet of paper. You will not be able to make it flat unless you tear the edges, deforming it.
The major reason for the oceans producing only 9% of Earth's biomass is d - Primary producers in the oceans are in effect limited by nutrients.
This is because the availability of essential nutrients such as nitrogen and phosphorus is limited in the ocean, and this limits the growth of primary producers such as plankton and seaweeds, which are the basis of the ocean food web.
As a result, there is much less biomass produced in the ocean than on land.
Final answer:
The major reason for the difference in biomass production between the world's oceans and land is the limited availability of nutrients for primary producers in the oceans and the complexity of food chains, resulting in a higher loss of biomass.
Explanation:
The major reason for the difference in biomass production between the world's oceans and land is the availability of nutrients and the complexity of food chains in the oceanic environment.
In the oceans, primary producers, such as phytoplankton, play a crucial role in biomass production. These microscopic organisms rely on nutrients like nitrogen and phosphorus to grow and reproduce. However, the availability of these nutrients in the ocean is often limited, which restricts the growth of primary producers and subsequently reduces the overall biomass production.
Furthermore, the food chains in the ocean are much more complex compared to those on land. As energy is transferred from one trophic level to another, some energy is lost as heat or used for metabolic processes. This energy loss results in a decrease in biomass at each successive trophic level. The complexity of the food chains in the ocean leads to a higher loss of biomass, contributing to the lower overall biomass production in the oceans.
Human activities, such as overfishing and pollution, also contribute to the decline in marine biomass. Overfishing disrupts the balance of marine ecosystems, leading to a decrease in the population of certain species and a subsequent decrease in biomass. Pollution, including nutrient runoff and oil spills, can also negatively impact marine ecosystems and reduce biomass production.

Answer:

Explanation:
Igneous rocks form when a volcano erupts and the hot lava cools. Igneous rocks have many different textures. The texture is determined by how quickly the rocks cool. Those that form on or near the surface tend to cool rapidly, giving the rock a fine grain, such as basalt, the most common rock on the ocean floor. Those igneous rocks that form deep below the surface tend to cool more slowly and, as a result, tend to be tough with a coarse grain, such as granite.
Mexico is mosstl known for its mineral abundance such as gold, and lead and for containing industrially important fuels like natural gas and petroleum.
Economically, mining is the country's most important activity.
