Bebe observes a child’s behavior after he has watched 15 minutes of violent cartoons. she codes the child’s behavior every 30 seconds according to whether he hits, kicks, pushes, or bites another child. this observational technique can best be described as observation.

systematic          

Explanation:

Systematic observation: The systematic observation is used either to disprove or support a hypothesis and is a form of calculated observation. An observation should be repeatable and bias-free to be systematic. In systematic observation, a hypothesis is being made by the researcher and then it is being tested through experimental methods.

Advantage:

1. It forms the basis of scientific inquiry.

2. Mode of getting or acquiring wisdom about the environment.

In the question above, the observational technique used by Bebe can best be described as a systematic observation.

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.

we need a diagram to you sorry
