Canada and Mexico’s importance to the United States is more than simply a border-state phenomenon. The trading relationship between United States and Canada represents the largest bilateral flow of income, goods, and services in the world. Meanwhile, Mexico is the United States’ second largest trading partner. Between NAFTA coming into effect and 2003, two-way trade between Canada and Mexico more than doubled.
The temporary visa category created for Mexican and Canadian NAFTA Professional Workers enabled 92,951 Canadians and 2,571 Mexicans to enter the United States on visas in 2001. In 2002, Mexico was the country of origin of the largest number of legal immigrant admissions to the U.S, and Mexicans represented about 29.8 percent of the total foreign-born population. In comparison, Canadian immigrant admissions were only 1.8 percent of total legal admissions.
The three regions are Melanesia, Micronesia, and Polynesia.
Answer:
When a rock undergoes mechanical weathering, it is broken into smaller and smaller pieces, each retaining the characteristics of the original material, abut increasing the surface area available for chemical attack. Wind, glacial ice, rivers, and waves.
Aquatic Biome
The aquatic biome consists of any part of Earth that is covered with water. This includes freshwater and salt water. The aquatic biome can be further divided into freshwater biomes, marine biomes, wetland biomes, coral reef biomes, and estuaries. These subdivisions are based on the salt content of the water, the aquatic plants that live there, and the aquatic animals that thrive there.
Forest Biome
The forest biome is the largest and has a wide variety of plants, trees, animals, insects, and microscopic organisms. The major characteristic of the forest biome is its trees. About 30% of the Earth is considered a part of the forest biome. The forest biome is subdivided by its climate and types of trees present. These subdivisions are: the rainforest biome, temperate biome, chaparral biome, alpine biome, and taiga biome.
Desert Biome
The desert biome has one major, distinguishing characteristic, the fact that it has very little vegetation. The climate is rather extreme depending on its location. The deserts of Africa are extremely hot during the winters and warm throughout the rest of the year. There are also cold deserts such as those in Antarctica. These deserts are extremely cold during the winter and cold during the other seasons.
Tundra Biome
Tundra biomes are the coldest places on Earth. They are similar to a cold desert except they receive less rainfall and contain different animals and plants. Even though the conditions are harsh, the tundra biome does have plant and animal habitats.
Grassland Biome
The grassland biome is made of rolling hills of various grasses. They receive just enough rain to sustain grass but not enough to grow many trees. There are a few trees that will grow in grasslands but sporadic wildfires keep them under control. There are two types of grassland, the savannas and temperate grasslands.
The bonds in the wood between the atoms in its structure contain potential energy. Lighting the wood on fire introduces a combustion reaction which ignites this energy. Potential energy is transformed into chemical energy as the wood burns to create heat, smoke (released into the air), and soot (by product of burning the wood).
