Tectonic Forces
Rocks are under stress when they are subjected to a force at depth. When the rocks are exposed at the surface after uplift and erosion, the effects of the stress can be studied. Stressed rocks show varying degrees of strain—the change in the volume and/or shape of the rock because of that stress. For example, a volcanic agglomerate may be compacted and its pyroclastic fragments stretched (strained) in response to a tectonic stress, such as compression.
Earth formed around 4.54 billion years ago by accretion<span> from the </span>solar nebula.<span> Volcanic </span>outgassing<span> probably created the primordial atmosphere and then the ocean; but the atmosphere contained almost no </span>oxygen<span> and so would have been toxic to most modern life including humans. Much of the Earth was molten because of frequent collisions with other bodies which led to extreme volcanism. A "giant impact" collision with a planet-sized body is thought to have been responsible for forming the Moon. Over time, the Earth cooled, causing the formation of a solid </span>crust<span>, and allowing liquid water to exist on the surface.

President Franklin Roosevelt executed his "Good Neighbor" policy towards Latin American Countries in 1933.
Regarding the policy, The United States stated that it would not interfere in any of the Latin American countries domestic affairs. This position of the US government also promoted the development of bilateral relations between countries that could later evolve into commercial agreements. This would eventually happen during the last decade of the 20th century and the start of the 21st century.
