Land plants face challenges such as predators (not specific only to land plants), gathering of water, natural disasters, changes in weather, becoming uprooted (by a number of events), and reproductive difficulties.
Predators is pretty obvious- fact that they can be eaten at any point.
Gathering of water- plants that live in water have an endless supply where the land plants must wait for rain.
Natural disaster- hurricanes, tornadoes, mud slides etc, all can destroy plants.
Changes in weather- example if it is spring and all the flowers and beginning to bloom and a snow storm hits, it can kill the flowers.
Becoming uprooted- animals, people, natural disasters, weather. All can uproot a plant.
Reproductive difficulties- rely on animals and insects to carry pollen, therefore allowing them to reproduce. Also must rely on weather. Some reproduce by letting the wind take the seeds or pollen where they need to go. In water this would be much easier with the constant movement of the water around them. Then for the seeds to grow they rely on all of the previous; predators not eating them, water, weather, good conditions all around.
Animal life is believed to actually have begun on land, with some animals later moving into the water. Simple animals are known to have developed as early as 2 billion years ago, with gradually more complex organisms appearing, until a very short and huge expansion of life. This is thought to have happened around 550 to 530 million years ago, in what is called the Cambrian explosion. Plant life is understood to have originated in the water, and then either moved onto land or some combination of movement with preexisting land growth. Evidence for plantlife on land is varied, some being as old as 1.2 billion years although the majority of the oldest remains are 450 million years old.
A leech moves by extending and contracting its body in a wave-like motion, using its suckers to grip onto surfaces. On land, a leech can use its muscular body to inch forward and navigate uneven terrain by contracting and stretching its body segments. They move slowly and rely on moisture to prevent dehydration.
Some shark species can swim close to shore in shallow waters, but they generally do not come onto land. Sharks rely on water to breathe and move, so they are not adapted to survive out of the water for extended periods of time.
Early animals likely evolved to move onto land to seek new resources and avoid predators. The changing environment, such as shrinking water sources and increasing competition for food, may have also played a role in driving animals to adapt and colonize new habitats on land. Additionally, the ability to exploit new niches and evolve adaptations for terrestrial life, such as lungs for breathing air, likely contributed to the transition.
Penguins jump to get from water onto land or ice floes, to escape predators, or to communicate with other penguins. They use their strong flippers to propel themselves out of the water and onto solid ground.
Light energy to photosynthesize made it beneficial for aquatic plants to move onto land. Terrestrial environments allowed the plants to be able to absorb more sunlight in contrast to living beneath the surface of water.
Plants moved onto land after algae was entrapped in evaporating ponds, and cast up to the sea shore, and as a majority died, a few survived to be the plants we see on land today.
A major trait that allowed plants to move onto and adapt to dry land was the development of a waxy cuticle on their leaves and stems. This cuticle helps prevent water loss and desiccation, allowing plants to thrive in terrestrial environments.
Algae are one of the oldest lineages, from before plants went onto land. Bryophytes are of the first lineage to live on land.
Desiccation, as land plants had to develop adaptations to prevent water loss from their tissues.

The development of an ozone layer in Earth's atmosphere allowed organisms to move onto land. The ozone layer absorbs the sun's harmful ultraviolet radiation, providing protection for early land-dwelling organisms. This helped pave the way for the colonization of land by plants and animals.
