Answer:
Wetlands are usually defined as the land that is submerged under shallow water, or the soil is saturated with water throughout the year. These inland wetland areas and coastal areas are affected both naturally as well as due to the human activities in different ways such as-
- Due to the increasing rate of water pollution, where the waste particles produced from the industries and factories, and are eventually mixed with the water and polluting it.
- Due to climate change also, these areas are affected.
- Tide also is another factor affecting these areas.
Three of the major harmful impacts of humans on coastal areas are-
- The pollution has increased in the coastal areas as the humans throw the waste materials here and there near to the sea, where these substances are later mixed with the water.
- Due to the setting up of different things such as seawalls, sea-fence, the rate of erosion has considerably increased.
- The marine life also is affected in the coastal areas, because humans often go for fishing in this area.
Three of the major harmful impacts of human on the freshwater ecosystem are-
- The construction of dams directly affects the aquatic species and also degraded the quality of the water.
- Due to the usage of waterways, these marine species are affected.
- A large number of radioactive waste, chemicals, and other waste materials are released from the industrial sectors which are responsible for affecting the freshwater ecosystem.
Answer:
The current trade deal between Canada, the US, and Mexico is USMCA.
Explanation:
The United States, Canada, and Mexico are the three countries that comprise North America. They are all large countries with strong economies, and even though Mexico is still a developing country its economy is very strong. In order to make things easier for each other, everyone to have a benefit, and make the region a global economic player as a unit, a trade deal was concluded a few decades ago, NAFTA.
While NAFTA was in place for several decades, the current administrations of the countries decided to review it and improve so that all member countries can have an even greater benefit. The new and improved deal set in place is USMCA. Like NAFTA, USMCA is a free trade agreement, but it has been made in a manner that economic freedom is even greater between the countries, while also making the region a type of economic union to counter and prevent the Chinese growing influence.
The statement; “The comet cools down and begins to glow brightly as a result of this decreased temperature.” is considered false. Study shows that comets can be seen because their comas and tails reflect the light from the sun or would usually glow as they absorb energy from the sun. Comets are provided with energy from the Sun , so its movement is always away from the Sun.
The correct answer is (c.) outer. The moon's average density is about the as the outer layer of the Earth. The average density of moon is about 3.34 g/cm<span>3 and the earth's outermost layer is almost similar to it. </span>
