Question

which solar - system components have been studied using manned and robotic spacecraft? select all that apply. a. moon b. sun c. meteors d. comets #4 true or false: earths magnetic field helps shield its surface from harmful solar radiation. explain your answer. #5 describe the characteristics of dwarf planets. #6 which of the following factors contributes to the occurrence of seasons on earth? select all that apply. a. earths axial tilt b. curvature of earths surface c. distance from the sun d. angle of sunlight

Explanation:

1. Manned and robotic spacecraft have studied the Moon, Sun, meteors, and comets. The Moon has been visited by astronauts and explored by rovers. The Sun is studied with space - based telescopes. Meteors and comets are observed and sometimes sampled.
2. Earth is a terrestrial planet with large oceans of liquid water.
3. One component of the solar system other than planets is asteroids. They are rocky bodies in orbit around the Sun.
4. Earth's magnetic field is like a shield. It deflects charged particles from the Sun, protecting the surface from harmful solar radiation. So the answer is True.
5. Dwarf planets are small, round bodies in orbit around the Sun that have not cleared their orbital neighborhood of other debris. Examples include Pluto, Eris, etc.
6. Earth's axial tilt and the angle of sunlight contribute to the seasons. The axial tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year. The curvature of the Earth's surface also plays a role in how sunlight is distributed. The distance from the Sun has a minor impact on seasons compared to the tilt.

Answer:

1. A. Moon, B. Sun, C. Meteors, D. Comets
2. Terrestrial
3. Asteroids
4. True
5. Small, round bodies in orbit around the Sun that have not cleared their orbital neighborhood of other debris.
6. A. Earth's axial tilt, D. Angle of sunlight
