Geography
1 answer:
Nana76 [90]4 years ago
5 0

Answer: Igneous Rock

Explanation: Radiometric dating is used to date rocks by measuring the decay of their composite materials. Stable isotopes remain the same over   time while the nucleus of an unstable or radioactive isotope will decay to form other isotopes .

Dating rocks using Isotopic methods uses the decay time of the isotope in the rock to assess its age. The accuracy of this method is assured by the fact that when these isotopes decay, they are retained in the rock. Isotopic dating is not very accurate in sedimentary rocks because they contain particles from older rocks.

What are the difficulties encountered by the senior high school students in online learning?
damaskus [11]

Due to the numerous distractions they experienced and the teachers' incapacity to maintain control of the online learning environment, some participants noted that learners found it difficult to focus throughout the sessions.

The study discovered the following difficulties that research students faced: 1) Lack of foundational knowledge from junior high school, 2) Formulating a Topic, 3) Dealing with a research team, 4) Inadequate Resources, 5) Data Analysis and Treatment, and 6) Maintaining motivation throughout the study. The majority of students find online learning to be boring and frequently lament their lack of drive to complete a course. Having a time management system is perhaps the hardest obstacle for students to overcome because it solely depends on self-motivation. Even professors frequently lament the lack of resources to make the classes engaging, leading to a loss of interest from both sides.
