We are out taking a walk one day when we notice two large fields. One is all grass while the other a mix of grass and native wil

d flowers. We wonder if there is a difference in the number of different bird species each field has using it. We think that the field with the grass and wild flowers will have more different bird species using it than the field with just the grass alone. We set up an experiment where we census the birds in each field. We census each field once a week for three months. Censuses are done on both fields at the same time and using the same techniques. We find that a total of 6 different bird species using the grass field and 10 different species using the grass and wildflower field.

The correct answer will be option-B.

Explanation:

A scientific approach to explain the natural phenomenon includes various steps which begin with the making the observation. The observation made the researcher skeptical to make a scientific question which could be answered by proposing a hypothesis.

Which items are described by the geographic theme of human-environmental interaction? A.The Pyrenees Mountains form the border b
iogann1982 [59]

Answer:

B. The Channel Tunnel connecting the United Kingdom and France reduced travel time between these nations

E. Land has been cleared to make room for France's famous vineyards

F. A highway through Mount Blanc connects Italy and France

Explanation:

One of the five themes of geography is the human-environmental interaction. The human-environmental interaction basically means that the humans and the environment interact with each other and affect each other, sometimes in positive manner, sometimes in negative manner. There are many examples for this geographic theme across the globe.

The Channel Tunnel between the UK and France is an underwater tunnel. Its purpose is to make the traveling easier and faster between the two nations. It has been built in the sea waters, and fortunately it is not having any negative impacts on the environment.

France is one of the biggest producers of vine in the world. In order to have the amount of grapes needed for France to produce lot of vine it needs lot of agricultural land. This has been accomplished by clearing the land from the wild vegetation over time. While this has had a very positive impact on the economy of France, it has had very negative effect on the wildlife as it has totally ruined the habitat for lot of species.

Italy and France are separated by a massive mountain range, the Alps. The Alps are very large and very high, but nonetheless the humans managed to find ways to build highways through them despite all the difficulties. The highways are state of art through the Alps, and they are very useful for the countries in the region as these highways connect them, and not making them isolted. It has not been so great for the environment though, as lot of changes have been done to the mountain range, and every day there's thousands of animals that die on the highways.

What climate will countries from the northern and southern hemispheres experience from having the least direct sunlight?(1 point
earnstyle [38]

Winter is the phase of year when countries in the northern and southern hemispheres, respectively, see the least amount of direct sunlight.

December, January, and February in the Northern Hemisphere and June, July, and August in the Southern Hemisphere are the months when a portion of the Earth experiences the least amount of daylight. The Earth's 23.5° axial tilt as it orbits the sun causes solitons and varying solar declinations. This indicates that, during the year, one of the hemispheres is tilted toward the sun and receives the most intense solar rays, while the other receives the least amount of sunlight.

To know more about axial tilt
