WRITE ANY 2 CAUSES OF CYCLONE IN POINTS, PLEASEEE​

Answers

Answer:

Cyclones are centred on areas of low atmospheric pressure, usually over warm ocean waters near the equator. The warm moist air over the ocean rises from the surface in the upward direction, resulting in the formation of the low-pressure zone over the surface. Air from the surrounding region, with higher pressure, pushes into the low-pressure area.

Cyclones, also known as hurricanes or typhoons, are primarily caused by high ocean temperatures, broad-scale wind systems and clustered thunderstorms, which liberate the heat energy from the ocean surface and transfer it to the cyclone. Ocean temperatures must be higher than 80 degrees Fahrenheit to a depth of at least 150 feet.

Which statement is true?

Which is a definition of "civil society"? That sphere of voluntary individual, social, and economic relationships and organizations that, although limited by law, is not part of governmental institutions. Civil society provides a domain where individuals are free from unreasonable interference from government. By providing for independent centers of power and influence, civil society is an indispensable means of maintaining limited government. The arena of uncoerced collective action around shared interests, purposes and values. In theory, its institutional forms are distinct from those of the state, family and market, though in practice, the boundaries between state, civil society, family and market are often complex, blurred and negotiated. Civil society commonly embraces a diversity of spaces, actors and institutional forms, varying in their degree of formality, autonomy and power. Civil societies are often populated by organizations such as registered charities, development non-governmental organizations, community groups, women's organizations, faith-based organizations, professional associations, trade unions, self-help groups, social movements, business associations, coalitions and advocacy groups. Refers to the set of institutions, organizations and behavior situated between the state, the business world, and the family.

What does magma erupt through to create volcanoes?​

Answers

When rock from the mantle melts, moves to the surface through the crust, and releases pent-up gases, volcanoes erupt. Extremely high temperature and pressure cause the rock to melt and become liquid rock or magma. When a large body of magma has formed, it rises thorugh the denser rock layers toward Earth's surface
Lava (magma that has erupted onto the Earth's surface) is visually mesmerizing – as the molten rock flows downhill, lava exposed to the air cools to a deep black color, while the molten rock beneath glows bright orange.This magma can push through holes or cracks in the crust, causing a volcanic eruption.

In which location are earthquakes least likely to occur?
O A. Where tectonic plates are being pushed apart
O B. Along a fault line at a tectonic plate boundary
O C. At the center of a tectonic plate
O D. Where tectonic plates are being pushed together

Answers

At the center of a tectonic plate is the location are earthquakes least likely to occur. Hence, option C is correct.

What is a tectonic plate?

Tectonic plates are massive pieces of the upper mantle and crust of the Earth. They are made up of both oceanic and continental crust. Earthquakes occur around mid-ocean ridges and important faults that create plate boundaries.

The heat generated by nuclear reactions taking place inside the planet's center causes the plates to move periodically toward and occasionally away from one another. This movement is also referred to as a tectonic shift.

There are four different types of boundaries between the tectonic plates as a result of their movement: divergent and convergent boundaries, transform fault boundaries, and plate boundary zones.

Thus, option C is correct.

The processes for building new land are called constructive forces. Three of the main constructive forces are crustal deformation, volcanic eruptions, and deposition of sediment Crustal deformation occurs when the shape of land (or crust) is changed or deformed.
