The air masses that have the greatest influence on weather conditions in the Midwestern United States are continental polar.
This air masses come from the north, they are heavy, low, cold and predominantly dry air masses, and are most intense in the colder part of the year. But they are not the only one, even though they are the dominant ones, the tropical warm and wet climate also has a big influence, especially in the warmer part of the year, and it's influence is gradually increasing.
The correct answers are:
- increased greenhouse gases;
The transportation system is one of the biggest emitters of greenhouse gases into the atmosphere, and this is due to the combustion of the fossil fuels, the end result being huge amounts of CO2 released in the air.
- increased pollution;
The energy sources used for the transportation systems are in general very damaging for the environment as they are letting out as a side product lots of pollutants.
- Easy movement of people, products, and ideas;
With the development of the transportation systems, the movement around the globe has become very easy and quick, and that has contributed to constant communication between people from all over the world, exchanging goods, ideas, technologies, as well as migration.
The statements that are correct for cooling magma are:
- When magma reaches the surface of Earth, thermal energy is transferred to the atmosphere and land surfaces by conduction and radiation;
- Magma can lose heat when it releases gases either underground or above ground;
- At depth magma loses thermal energy to the surrounding rocks by conduction;
- And groundwater can receive heat from magma by conduction.
<h3>What is magma?</h3>
Magma can be regarded as the mixture of molten rock that do forces itself to the surface of the Earth.
At the depth of the ground , it should be noted that magma loses thermal energy to the surrounding rocks by conduction.
