Question

whats thought to be responsible for causing venuss retrograde rotation? a) gravitational pull from earth and mercury b) the composition of venuss atmosphere c) venuss high surface temperature d) tidal forces from the sun on venuss atmosphere question 18 (5 points) whats the inner core of the jovian planets made of? a) helium gas, hydrogen gas, and rocks b) metals, helium gas, and hydrogen gas c) bacteria fossils, hydrogen compounds, and ice crystals d) hydrogen compounds, solid rock, and metals

Explanation:

1. For the first question about Venus's retrograde rotation, tidal forces from the sun on Venus's atmosphere are thought to be a possible cause. The gravitational - interaction between the sun and Venus's thick atmosphere can affect its rotation.
2. For the second question about the inner core of Jovian planets, they are believed to have a core made of hydrogen compounds, solid rock, and metals. The high - pressure environment in the core allows for such composition.

Answer:

1. D. Tidal forces from the sun on Venus's atmosphere
2. D. Hydrogen compounds, solid rock, and metals
