Question

Which of earth’s spheres do mountains, lakes, trees, clouds, ice, and snow represent? (which sphere does each one belong in?)?

Answer 1

Lakes and ice are the hydrosphere. Mountains and trees are the lithosphere. Clouds are the atmosphere. Snow is debatable, but I would say it fits in the atmosphere, since it generally flows through air, and isn't ever a permanent fixture on the planet's surface (lithosphere). While it is composed from water, it doesn't exist in or around the ocean for more than extremely brief periods, so it doesn't qualify for the hydrosphere. Ice is also debatable I suppose, but I took it to mean naturally occurring ice in glaciers, which constantly freeze and unfreeze in the ocean. Ice generally doesn't describe what we would consider "land", even if it forms the top layer of ground in many arctic and antarctic environments.
