Explain how warfare changed during this time, i. e. guns, chemical warfare, planes, strategies.

Guns became less efficient.

Explanation:

One Bullet shot by guns might not kill a fully vested soldier. One drop of atomic bomb will kill  hundreds of thousands of people.

The atomic bomb that dropped By United States in Hiroshima and Nagasaki killed more than 200,000 people . This the atomic Bomb that's developed in 1945 and effectively ended the world war II.

In 2020, the development of nuclear technology far surpassed what we had in 1945s. Which made the use of guns almost obsolete.

If another world war happen in the future, the use of Planes (as medium of transportation) and Chemicals warfare's will be the most efficient methods to destroy the opposition.

the correct answer is 2.

a slump in geology means a mass movement process of slope failure. a mass of rock or unconsolidated material drops along a slip surface. in other words, rock layers move a short distance down the slope. the slump block is an intact block (2), without any landslide material.

in this image, 1 is the surface of rapture (scarp), 2 the slump block, 3 main scarp (crown), 4 base of rapture with debris flow.

slumps are caused by clear cutting on unstable soils and the sagging of earth, in coastal areas they are due to wave infiltration.
