Read about a process that helps shape Earth’s surface. Water on Earth’s surface seeps into rocks. When water in the cracks freezes, it expands and breaks the rocks apart. This process is called frost wedging.

Which spheres interact when this process occurs?

atmosphere, biosphere, cryosphere
hydrosphere, cryosphere, geosphere
biosphere, hydrosphere, cryosphere
cryosphere, atmosphere, geosphere

Under the action of a constant force an object accelerates at 7.8 m/s2. what will the acceleration be if (a) the force is halved? (b) the object's mass is halved? (c) the force and the object's mass are both halved? (d) the force is halved and the object's mass is doubled?

Acarpenter builds an exterior house wall with a layer of wood 2.9 cm thick on the outside and a layer of styrofoam insulation 2.3 cm thick on the inside wall surface. the wood has k=0.080w/(m⋅k), and the styrofoam has k= 0.010 w/(m⋅k). the interior surface temperature is 19.0 ∘c , and the exterior surface temperature is -15.0 ∘c . a.)what is the temperature at the plane where the wood meets the styrofoam? celsius b.)what is the rate of heat flow per square meter through this wall? /m^2

Aparticle moves in a circle 1.50 m in radius . through what angle in radians does it rotate if it moves through an arc length of 2.50m? what is the angle in degrees?
