How to send ETH on Coinbase?

Could you please elaborate on the steps involved in sending Ethereum (ETH) using Coinbase? As a new user to the platform, I'm seeking a clear and concise explanation of the process. I understand that security is paramount, so I'm interested in knowing if there are any specific measures I should take to ensure the safety of my transaction. Additionally, I'd like to know if there are any fees associated with sending ETH and how long it typically takes for the transaction to be processed and completed. Could you guide me through this process from start to finish?
