earth/space test review

major movement of the oceans that results from the gravitational attraction of the moon

the tilt of the earth's axis is approximately 23 degrees

which term describes the shape of the orbit of a planet?

the role of gravity and centripetal force in the motion of planets around the sun

when the distance between objects increases, gravitational force decreases

the point when earth is farthest from the sun

at what point in Earth's orbit is Earth closest to the sun?

low eccentricity results in very elliptical orbits

ratio of the distance between the foci and the length of the major axis of an ellipse

a solar nebula is.....

tide of increased range occurring near times of a full and a new moon

an apple falls from a tree.  what causes it?

the process whereby dust and gas accumulates into larger bodies, like stars and planets

High eccentricity results in very elliptical orbits

rotating cloud of gas and dust from which the sun and planets form

which stage in the formation of the solar system came first?

seasons are caused by the earth's nearness to the sun

what term best describes the shape of the orbits of planets in our solar system?

As a planet moves around its orbit, the planet sweeps out equal areas in equal amounts of time

the orbit of a planet around the sun is an ellipse, and the sun is one focus of the ellipse

when the masses of objects increase, gravitational force decreases.

the tide of decreased range occurring near times of the first and last quarter of the moon

which stage came latest in the formation of the solar system?

which will result in the greatest gravitational force?

which describes a small body from which a planet forms?

the square of a planet's orbital period is = to the cube of the planet's distance from the sun.

the point at which earth is closest to the sun

a model for a planetesimal might look like.....

when the masses of objects decrease, the distance between objects decreases

Gravity caused the solar nebula to collapse toward the center, making the center dense and hot.
