What are the latest developments on research on Earth’s internal structure.

The internal structure of the earth is like a steel ball that has been inserted into the middle of a rubber ball that has then been rolled around in the mud which sticks to it.

Explanation:

The mud sticking unevenly on the outside of the ball represents the earth's crust. The rubber ball represents the mantle below the crust, and the steel ball inside is the earth's core. These are the basic layers.

Inside the earth, the mantle itself consists of an upper mantle and a lower mantel, and the iron consists of an outer core and inner core. The separations occur where the state of the substance changes. For the iron , the outer core is closer to a liquid, while the inner core is closer to a solid. Both are intensely hot.

If you need a 3-D representation of the internal structure of the earth, cut a spherically shaped avocado in half, and keep the half with the seed or pit. The pit is the core, the fruit is the mantel and the skin is the earth's crust. You can add in the other divisions as necessary.

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
