Final answer:
Aid given after a natural disaster like a tornado is typically provided by a categorical grant, a type of aid that comes with specific guidelines on its usage. These grants are preferred for their targeted approach in disaster relief and often require matching funds from the state. NGOs also play a vital role in providing humanitarian aid in such situations.
Step-by-step explanation:
Aid given after a natural disaster such as a tornado is provided by a categorical grant. This type of grant is where one level of government, usually the federal government, grants money to states or local governments for specific purposes. In the context of emergency relief, this aid is used to help communities recover from the devastating effects of disasters. Categorical grants involve conditions set by the grantor, ensuring that the funds are used specifically for disaster relief efforts. In contrast to block grants which have fewer restrictions and are more broadly used, categorical grants offer more control over how the funds are spent, which is why they are often preferred in situations where immediate and directed assistance is necessary.
Historical examples such as the response to Hurricane Katrina reflect the national government's preference to extend support through categorical grants, especially in times of national emergency. Moreover, these types of grants often involve contribution in the form of matching funds from the state that receives them.
Other organizations that can contribute to aid efforts after disasters like tornadoes include nongovernmental organizations (NGOs) such as the Red Cross and CARE, which can provide immediate humanitarian aid in various forms, including food and medical assistance.
