Forming a hypothesis is the second step in a scientific investigation. this step is derived from two goals of psychology—description and

Explanation.

Scientific investigation is the process in which investigators and researchers use a methodical strategy to elucidate mysteries about the world around us.

A  scientific investigation typically starts with observations. Observations usually lead to mysteries.  A scientific investigation starts by formulating a hypothesis which is a probably the rational response to a scientific question, based on scientific knowledge. A prognostication is a statement which indicates all the possibilities under specific conditions.

The right answer is Explanation

Explanation:

The scientific method is a step by step procedure that is useful for researchers to follow in order to determine if there is any kind of relationship between the variables. Particularly, psychologist researchers try to find the cause of a behavior as much as the prediction and change of the human behavior in general. The researcher will form a hypothesis about what they expect to happen between to variables and with this goes to explain the question the investigator is asking about their study.  

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.
