Answer:
Imbalance occur when the hydrogen of the star's core used up.
Explanation:
Both gravity (hydrostatic) and pressure (thermal) create an equilibrium state during star formation. A star is in the state of hydrostatic equilibrium when the pressure that is created due to core burning is in balance with the force of gravity. These two will be in equilibrium when the outer push of core is in equal amount to the inward push of gravity. When the hydrogen that is present in the star's core has been used up, burning stops, which leads to the imbalance of gravity and pressure. This imbalance the star which undergo significant changes in its shape and structure..
Tombolo is associated with an island just offshore of a beach.
A tombolo is a depositional feature that is formed when the longshore current, moving parallel to the sea shore, carries the sand long with them and deposits along the shoreline. It is associated with an island just offshore of a beach while the tombolo is connecting a large piece of land with a small island.
It has a part that is usually sandy, and it looks as a natural bridge or trail that is connecting two pieces of land, and that is what occasionally can make a confusion. It is situated just offshore of a beach.
