Three disasters formed by tectonic forces include earthquakes, volcanic eruptions, and tsunamis. Earthquakes occur when stress builds up along fault lines, releasing energy suddenly. Volcanic eruptions result from magma rising to the surface due to tectonic activity, often leading to lava flows and ash clouds. Tsunamis can be triggered by underwater earthquakes, causing massive waves that inundate coastal areas.
At a divergent boundary, three key geological features are formed: mid-ocean ridges, where tectonic plates pull apart and new oceanic crust is created; rift valleys, which occur on land as continental plates separate; and volcanic activity, as magma rises to fill the gap created by the diverging plates. These processes contribute to the continuous renewal of the Earth's crust.

there is a possibility, it depends on how strong the quake is, tsunamis do not occur on a type 2-3 quakes, tsunamis occur during the shift of the tectonic plates under the ground. quakes with intensity of 2-3 often develop cyclones or whirlpools. but immediately evacuate the area if an earthquake is occurring.
Land began to appear on Earth around 3 billion years ago during the Archean Eon, as volcanic activity and tectonic processes led to the formation of the first continental crust. Prior to this, the planet's surface was primarily covered by oceans. Over time, tectonic movements and geological processes contributed to the growth and diversification of landmasses. The continuous reshaping of the Earth's surface has since resulted in the continents as we know them today.
convection currents
Volcanic activity: Mountains can form through volcanic eruptions where molten rock rises to the surface and solidifies. Tectonic plate movement: Mountains can be formed when two tectonic plates collide, causing intense pressure and uplifting of the Earth's crust. Erosion and weathering: Mountains can be shaped by erosion and weathering over long periods of time, where forces like wind and water wear down the land to create mountainous terrain.

Greenland was formed through a combination of tectonic activity and volcanic processes. It originally formed around 3 billion years ago as part of the ancient supercontinent of Rodinia. Over time, shifts in the Earth's crust led to the separation of Greenland from other landmasses.
The three internal forces in the Earth are mantle convection, gravity, and radioactive decay. Mantle convection drives the movement of tectonic plates, gravity affects mass distribution and generates stress in the crust, and radioactive decay produces heat that contributes to the Earth's internal energy.
The Federal Government ref. : FM 3-0, para 3-101. Provide Support in Response to Disaster or Terrorist Attack 3-101. Policies issued by the Federal government govern the support Army forces provide in response to disaster or a damaging attack on the homeland. In the event of disaster or attack, Army forces support civil authorities with essential services including: 􀁺 Performing rescues. 􀁺 Providing emergency medical care. 􀁺 Preventing epidemic disease. 􀁺 Providing food and water. 􀁺 Providing emergency shelter. 􀁺 Providing basic sanitation (sewage and garbage disposal). 􀁺 Providing minimum essential access to affected areas.
Fold mountains are typically formed in three main stages: 1) compression, where tectonic plates collide and push against each other, causing rocks to fold and deform; 2) uplift, where the folded rocks are pushed upward by tectonic forces, forming mountain ranges; and 3) erosion, where external forces like wind and water wear down the mountains over time. The cycle of formation, uplift, and erosion can repeat over millions of years, shaping the landscape of fold mountains.
