Short summary
This study presents a novel scheme for simulating Earth's free surface. Traditional methods like 'Sticky Air' in the Eulerian scheme face limitations such as increased computational costs and marker fluctuation issues. Our approach integrates the 'Sticky Air' concept into an Arbitrary Lagrangian–Eulerian framework using an internal boundary enabling a true free surface simulation, which reduces marker noise and enhances numerical stability.

This study examines how high temperatures can alter the chemical record in zircon crystals used to date rock events. Using computer simulations, we model how movement of atoms, radioactive decay, and the formation of new elements interact in a zircon under changing heat conditions. Our simulation is compared with measurements from rocks in southern India to estimate temperature history of the region. The work aims to improve insights from rock dating and our understanding of Earth’s past.

Two-thirds of the world's most populated cities are situated close to deltas. We use computer simulations to understand how deltas sink or rise in response to climate-driven sea level changes that operate from thousands to millions of years. Our research shows that because of the interaction between the outer layers of the Earth, sediment transport, and sea level changes deltas develop a self-regulated mechanism that modifies the space they need to gain or lose land.

Short summary
Knowledge of the internal structures of the major continental ice sheets is improving, thanks to new investigative techniques. These structures are an essential indication of the flow behavior and dynamics of ice transport, which in turn is important for understanding the actual impact of the vast amounts of water trapped in continental ice sheets on global sea-level rise. The software studied here is specifically designed to simulate such structures and their evolution.

Short summary
This study introduces a novel framework combining geodynamic and surface process models, enhancing our understanding of Earth's crust and upper mantle deformation. By integrating the codes Underworld 2 and Badlands within the Arbitrary Lagrangian-Eulerian with Internal Boundary (ALE-IB) scheme, our approach overcomes the limitations of previous methods. It maintains internal interface integrity and precise surface tracking, improving simulation fidelity.
