Soil particles are classified by size. The size
of the soil particle gives texture to the soil and
determines the amount of air and moisture
that exists in the soil.
Clay particles measure less than 0.002 mm. Clay is the smallest type of soil particle.
Silt particles measure 0.06 mm to 0.002 mm. Silt's particles are larger than clay particles but smaller than sand particles. Sand particles measure 2.0 mm to 0.06 mm. Sand is the largest type of soil particle, and due to its size, allows quick drainage and plenty of airflow.
Clay particles measure less than 0.002 mm. Clay is the smallest type of soil particle.
Silt particles measure 0.06 mm to 0.002 mm. Silt's particles are larger than clay particles but smaller than sand particles. Sand particles measure 2.0 mm to 0.06 mm. Sand is the largest type of soil particle, and due to its size, allows quick drainage and plenty of airflow.
Online teaching refers to the presentation
and learning of courses over the Internet
through the explicit use of technology and
computer networking systems. Courses can
be designed for a handful of enrolled students
or can be made open and accessible to a
wide variety of participants, such as with
a MOOC (Massive Open Online Course).
So, Assertion (A) is true. However, only the
mode of delivery of the course is different
here. There is no difference in the learning
gains made by the learner as compared to the
conventional classroom mode. So, Reason
(R) is false.
Social media refers to websites and
applications that are designed to allow people
to share content quickly, efficiently, and in
real-time. Blog is a form of social media;
others are social networking sites, social
news, media-sharing, etc. So,Assertion (A)
