Final answer:
The most common forms of volunteering abroad are Humanitarian Aid, providing immediate crisis response, and International Development, focusing on long-term economic, social, and political improvements.
Step-by-step explanation:
Two of the most common forms of volunteering abroad include Humanitarian Aid and International Development. Humanitarian Aid involves responding quickly to immediate crises such as conflicts, natural disasters, or mass displacement, often represented by organizations like Doctors Without Borders and the International Red Cross. These efforts provide short-term disaster relief to meet urgent community needs. On the other hand, International Development focuses on long-term systematic issues related to economic, social, and political development through human rights, diplomacy, advocacy, economic infrastructure, and capacity building. It aims to create sustainable improvements in the quality of life within international communities.
