Which part of the hydrologic cycle is NOT affected by gravity?

What is the ultimate source of energy for the hydrologic cycle?

Rocks break down into smaller pieces by a physical means; the chemical composition of a rock does not change.

Which is NOT a form of mechanical weathering?

Which example of mechanical weathering is being described:

Water can freeze in small openings in rock and as it expands it breaks the rock.

Which example of mechanical weathering is being described:

Roots and plants break rock into smaller pieces and animals burrow exposing more rock.

Which example of mechanical weathering is being described:

Force of water (ex. waves) breaks down rock.

Which example of mechanical weathering is being described:

The movements of water and wind can expose rocks to friction and abrasion from other rocks.

Which example of mechanical weathering is being described:

Avalanches or rock slides can expose new rock surfaces for weathering.

The process by which rock is broken down because of chemical interactions with the environment. This happens most commonly in hot, wet climates.

Which example of chemical weathering is being described:

A chemical reaction that involves an atom or a molecule losing electrons in a chemical reaction.

Which example of chemical weathering is being described:

Process of rock minerals reacting with carbonic acid dissolves or breaks down minerals in the rock.

Which example of chemical weathering is being described:

A chemical reaction caused by water which changes the chemical composition of minerals in rock.

Which example of chemical weathering is being described:

Compounds that combine with water in the atmosphere to produce weak acids and fall to Earth.

_____________________ is the process by which softer, less weather resistant rocks wear away at a faster rate than harder, more weather resistant rocks do, weathering at a SLOWER rate.

Water infiltrates easily from surface

Water trapped by impermeable rock or clay– between layers of rock

___________________ determines the total amount of water a material will hold depends on the number and size of pores in soil

___________________ the ease at which water passes through material – affected by sorting.

Using the image provided, what is the order from greatest porosity to least porosity?

The figure shows how sharp, angular rocks become smooth and rounded as they are subjected to greater _________________________ over time.

__________________turns iron minerals a brown-red color because the minerals react with oxygen in the air.
