Answer:
<em>a. compacting the soil, decreasing aeration and infiltration.</em>
Explanation:
Soil have pores and openings through which air enter the soil for aeration. This pores also allow water to infiltrate into the soil when moisture falls on the soil. Constant walking around the Plants all day can compact the soil, pushing the soil grains closer, and eliminating any space between the grains. This prevents air from entering the soil, and also impedes infiltration of moisture into the soil. When this happens, the plants on the soil becomes starved of an optimum amount of moisture and air necessary for proper growth and development.
West coast climate is belongs to the Köppen classification characterized by equable climates with rare cases of extremes of temperature. This climate is usually located in countries along the west coast of mid-latitude continents. The country with this type of climate is Italy.
The farther up you go the more light is absorbed at higher altitudes compared to the lower stratosphere<span>, so the </span>temperature increases
<span>In the 20th century, the scientist believed
that the floor of the ocean floor is flat. But later on discovered that their
theory is wrong. The ocean floor is not flat and featureless. One technology
helped the scientist to study in advance and in details the real feature of the
ocean floor. They used sound waves to know the distance of the water from floor
level to the top. They also discovered that ranges of mountains lies under the
ocean. Sonar was one of the technologies they used to study the sound waves
emitted by the ocean.</span>
The population growth of Europe is decreasing.
Explanation:
Europe, as a continent, is in the worst demographic situation. It is the only continent where it is predicted that the population will be decreasing in the coming decades. In fact, the majority of the countries in Europe have minimal population growth or have decrease in their populations already.
Taken as a whole, the continent experiences decrease in the population growth. This is due to the significantly lowered birthrates, so there is less and less young population, and more and more old population, thus aging populations. Over time, there will be less and less people for reproduction, and if the current trend continue, the continent will experience sharp decline in population in few decades.
The top three countries by population growth in Europe are:
- Luxembourg (1.90)
- Cyprus (1.27)
- Ireland (1.11)
The bottom three countries with largest population decline are:
- Latvia (-1.10)
- Lithuania (-1.10)
- Moldova (-1.06)
