how is Nginx finding default root

I just installed nginx using brew and its default config is located at /usr/local/etc/nginx. The server configuration in default conf file is as below (only small portion pasted)

server {
        listen       8080;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }
...
}

The location from which the index.html is being served is /usr/local/var/www/. Now, looking at the above configuration, I don’t understand how nginx goes to /usr/local/var/www/ to look for default file? Is there a different configuration that directs nginx to look into that folder?

    Setting it like this root html makes nginx use relative location.
    The easiest way is to have the root written with the full desired path like this

    root /var/www/html;

    1. If a value of the root directive is relative, the full path is composed using the nginx prefix. See that answer for details.
    2. In the nginx Homebrew formula the --prefix is set to the Homebrew prefix:
          --prefix=#{prefix}
    1. The default Homebrew prefix is /usr/local on Intel.
    2. Thus, the root is html → /usr/local/html (the nginx prefix + the relative path).
    3. In the nginx Hombebrew formula this location is symlinked to #{HOMEBREW_PREFIX}/var/www, that is, to /usr/local/var/www:
    # nginx's docroot is #{prefix}/html, this isn't useful, so we symlink it
# to #{HOMEBREW_PREFIX}/var/www. The reason we symlink instead of patching
# is so the user can redirect it easily to something else if they choose.
