What is the source of pressure in the core of a red giant that resists the force of gravity?
The energy produced by the star, which manifests itself as heat.
What is the relationship between a giant and a white dwarf?
A red giant is old to middle aged star and a white dwarf is dead star so the relationship is they are both are dead and alive.
What type of relationship exists between hermit crabs and giant tritons?
Ah, hermit crabs and giant tritons have a fascinating relationship in the ocean. You see, hermit crabs often use empty shells for protection, and the giant tritons, well, they like to snack on these hermit crabs. It's all part of the circle of life in the beautiful underwater world, where each creature plays a unique role.
What is the role of gravity in a red giant?
In a red giant, gravity plays a crucial role in the star's structure and evolution. As a star exhausts its hydrogen fuel in the core, gravitational forces cause the core to contract under its own weight, increasing temperature and pressure. This triggers hydrogen fusion in a surrounding shell, leading to the expansion of the outer layers and the star's transformation into a red giant. Ultimately, gravity balances the outward pressure from fusion, determining the star's stability and the processes that follow in its later stages.
What determines how large a star gets?
The mass of a star primarily determines its size. Stars with greater mass will be larger, as there is a balance between internal pressure from nuclear fusion and gravity pulling the star inward. Higher mass stars have more fusion reactions occurring in their cores, creating more pressure to counteract gravity and resulting in larger sizes.
When a star has exhausted its supply of hydrogen?
When hydrogen in the core of the star is depleted, a balance no longer exists between pressure and gravity. Core contracts, temperatures incrase. This causes outer layers to expand and cool. This star is called a GIANT.
What is the gravity on a super giant?
It depends what mass it has. But usually the gravity there is weaker than in our Sun.
What happens as gravity increases to the pressure on the matter within a star?
As gravity increases so the pressure within the star increases, the matter becomes more dense and hotter, more matter is fused. The star decreases in volume initially. The thermal pressure increases to maintain equilibrium.Depending on the total mass the star may then expand to a giant or 'explode' catastrophically as a nova.
What happens when the outward force of pressure wins out over gravity in an old star?
When the outward force of pressure wins over gravity in an old star, the star will expand and cool, becoming a red giant. This process occurs as the star exhausts its nuclear fuel and transitions to a different phase of stellar evolution.
What relationship do the algae have with the giant clams?

Giant waves produced by gravity are called?

What aspect of the gas giant has the biggest affect on their rings and satellitess?
The gravitational pull of gas giants has the most significant effect on their rings and satellites. This strong gravity influences the orbits and stability of their moons and can shape the structure of their rings by attracting particles and debris. Additionally, gravitational interactions with nearby moons can create gaps and waves within the rings, highlighting the dynamic relationship between the gas giant and its surrounding material.
