Answer:
1.<u> </u><u>Boiling point, 2. Convection, 3. does not exist</u>
Explanation:
- The behavior of the rocks is influenced by the temperature and pressure conditions inside the earth, this also includes the rate of stress applied upon the rock mass. More the heat and pressure of rocks more will be here transformation.
- Convective currents that rise from the asthenosphere are responsible for the movement of plates from the source, as these forces cause the plates to rotate and break up when the gases are released from below the surface of the earth in a very sudden manner.
- The layers found within the earth are called core crust and mantle but no such layer atmosphere exists on or above the surface of the earth in any form what so ever.
The boundaries between the Indian and the Somali plate and the one between the Indian and the Eurasian plates, are different types of boundaries, thus the land forms differ from one another.
The boundary between the Indian and the Somali plate is a divergent plate boundary. The land forms that appear on and around the boundary are dominated by rift valleys and steep mountains and hills that have been cut/separated because of the divergence.
The boundary between the Indian and the Eurasian plates is a convergent boundary between two continental plates. In here, both plates push against each other, creating a lot of pressure on the land, so the land has been lifting up continuously for several million years, creating the Himalayan Mountain Range which dominates the landscape.

<h3>This paper traces the history of human-environment interactions in the Pacific Islands during the last millennium, focusing on three main periods: the Little Climatic Optimum, the Little Ice Age, and, in greatest detail, the transition around A.D. 1300 between the two. The Little Climatic Optimum (approximately A.D. 750–1300) was marked by warm, rising temperatures, rising sea level and probably increasing aridity. The latter condition was linked to development of water-conservatory strategies (agricultural terracing being the most common) requiring cooperation between human groups which facilitated formation of large nucleated settlements and increased sociopolitical complexity. The transition period (approximately A.D. 1270–1475) involved rapid temperature and sea-level fall, perhaps a short-lived precipitation increase. Temperature fall stressed crops and reef organisms, sea-level fall lowered water tables and exposed reef surfaces reducing their potential as food resources for coastal dwellers. Increased precipitation washed away exposed infrastructure. Consequently food resource bases on many islands diminished abruptly across the transition. The Little Ice Age (approximately A.D. 1300–1800) was marked by cooler temperatures and lower sea levels. The lingering effects of the earlier transition largely determined human lifestyles during this period. Conflict resulted from resource depletion. Unprotected coastal settlements were abandoned in favour of fortified inland, often upland, settlements. Climate change is suggested to have been a important determinant of human cultural change during the last millennium in the Pacific Islands.</h3>

Answer:
The best answer to the question: The greenhouse effect is driven by the fact that greenhouse gases are:___, would be: Good absorbers of radiation at all wavelengths.
Explanation:
Under normal circumstances, the Earth receives energy from the sun and also produces a bit of its own energy. The energy that arrives from the sun is usually known as shortwave radiation, while the energy that is both absorbed by the Earth´s atmosphere, and the energy produced by Earth itself, becomes part of what is known as the longwave radiation. Greenhouse gases, like water vapor, carbon dioxide and methane trap both longwave and shortwave radiation, which should usually be expelled to a certain extent towards space, and maintain them trapped inside the atmosphere. This bouncing effect between the shield created by the gases and the lower atmosphere, should normally be controlled by the amount of atoms of gases in the higher atmosphere. However, in the greenhouse effect, what is happening is that the amount of gases is too high, and therefore they are trapping most of the radiation, both longwave and shortwave, and keeping it in, allowing the climate to warm up.
