USA HISTORY

Detailed explanation-1: -In the ionosphere, the ions of the solar wind collide with atoms of oxygen and nitrogen from Earth’s atmosphere. The energy released during these collisions causes a colorful glowing halo around the poles-an aurora. Most auroras happen about 97-1, 000 kilometers (60-620 miles) above Earth’s surface.

Detailed explanation-2: -An aurora (PL: auroras or aurorae), also commonly known as the polar lights, is a natural light display in Earth’s sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic).

Detailed explanation-3: -Lincoln’s legacy is based on his momentous achievements: he successfully waged a political struggle and civil war that preserved the Union, ended slavery, and created the possibility of civil and social freedom for African-Americans.

Detailed explanation-4: -The Northern Lights, Aurora Borealis, appear in a clear night sky as swirling rivers of greenish-blue light. They move and dance unpredictably; sometimes barely perceptible, then suddenly growing vivid. In simple terms, the auroras can be explained as an interaction of the solar wind and the Earth’s magnetic field.
