Sir confirm AMA (area minimum altitude) and grid MORA are the same?

[@AVIATIONAIRTRAFFICCONTROL]

Area minimum altitude also referred as minimum off-route altitude. provides minimum obstacle clearance above all obstacles in the area. Normally this means 2000 ft over high terrain or in mountainous areas and 1000 ft otherwise.

what about MRA

[@AVIATIONAIRTRAFFICCONTROL]

MRA is minimum reception altitude below which navaid signals will not be available to the aircraft
