Schema: it is a second-level organizational grouping, within a database.Every time you create a database, Snowflake will automatically create two schemas for you i.e.,INFORMATION_SCHEMA,PUBLIC schema.
INFORMATION_SCHEMA: schema holds a collection of views, it cannot be deleted (dropped), renamed, or moved.
PUBLIC: schema is created empty and you can fill it with tables, views and other things over time, it can be dropped, renamed, or moved at any time.
