Tanah liat primer (residu) adalah jenis tanah liat yang dihasilkan dari pelapukan batuan feldspatik oleh tenaga endogen yang tidak berpindah dari batuan induk (batuan asalnya).Karena tanah liat ini tidak berpindah tempat maka sifatnya lebih murni dibandingkan dengan tanah liat sekunder.Selain tenaga air, tenaga uap panas yang keluar dari dalam bumi juga mempunyai andil dalam pembentukan tanah liat primer. Karena tidak ...

Physical Changes Clay Once Burned
The first change that occurs in the primary and secondary clay when burned, is the loss of free water.

An interaction between the Earth’s atmosphere containing gas with the earth’s surface will provide mutual influence. By the time the Earth cooled, the water vapor in the atmosphere in the form of gas begin to condense and there was rain. Rain water ...

Primary clay (residues) is a type of clay that is produced from the weathering of rocks feldspatik by endogenous force that does not move from the parent rock (rock origin) .Because this clay does not move then it is more pure than the clay sekunder.Selain hydropower , hot steam coming out of the earth also have contributed to the formation ...
