What most likely happened to cause this mountain to form?

The Earth’s plates push together causing the crust to rise up and form mountains.

Fifty years from today this mountain will not look like this because….

Physical weathering will cause some of the sharp peaks to become rounded.

Which of the following processes will produce igneous rocks? A.deposition of sediments B.volcanic action C.earthquake activity D.erosion of surface rocks

Volcanic activity

What process is mostly responsible for the breaking down of the rock cliff into sand- sized sediment?

Weathering

What agent of erosion is causing the weathering of the cliff?

The erosion agent is: ocean waves.

The cross section below shows sedimentary rock layers containing fossils. Assuming that these rock layers have not been overturned, which fossil is in the layer that was formed most recently?

This shell is in the layer of rock that was formed most recently.

Look at the sedimentary tube below. What soil is located at station B? A. B. C. D. SiltGravel SandClay

A. B. C. D.

Which rock layer was formed first?

R

In which type of rock is the fossil imprint of a fern leaf most likely to be found? A.igneous B.sedimentary C.metamorphic D. volcanic

sedimentary

The diagrams below represent two different geologic cross sections in which an igneous formation is found in sedimentary bedrock layers. The layers have not been overturned. Which statement best describes the relative age of each the rock layers? A.Rock layer 1 is younger than layer 3. B.Rock layer 4 is older than 5 and 6. C.Rock layer 3 is the youngest. D.Rock layer 2 is the oldest.

A.Rock layer 4 is older than 5 and 6. We know that rock layer 4 was formed before 5 and 6 because it is underneath the other two layers. Layers on top are generally the youngest rock layers.

The map below shows the probable location of some of the continents at one time in the past. What feature of the continents best suggests that they were once joined? A.Some continents fit together like puzzle parts. B.Some continents are the same size. C.All continents have mountain ranges. D.All continents contain the same crustal composition.

A.Some continents fit together like puzzle parts.

Which of Earth’s layers has the following characteristics? Its regions are both made of iron and nickel. The outer region is molten, while the inner region is solid. It is the hottest of Earth’s layers.

The Core!

What layer of the Earth is made up of magma?

The Mantle

The surface of Earth is covered mostly by 1.solid rock 2.Ice 3.molten rock 4.water

Water

Look at the sections of the Earth’s crust below. Which section represents the size of Earth’s crust? ABCDABCD

B

What happens to the force of gravity between objects as the distance increases?

The force of gravity decreases.

Mercury, Venus, Earth, Mars Which statement is not true about these planets? They are made of dirt and rock They are the planets with water They are the closest planets to the sun They are all in orbit

They are the planets with water. Earth is the only planet known to have water among the 4 names.

The gaseous planets are:

Jupiter Saturn Uranus Neptune Jupiter Saturn Uranus Neptune

Jimmy is standing on Venus and looking at the Earth. It is dark on Moon, but daytime on Earth. Why do you think this has occurred? Moon Earth

The sun is shining on the opposite side of Venus where Jimmy is standing. The side of Earth he is looking at has the sun hitting it.

The Earth’s orbit around the Sun is called _________ and takes ________ amount of time.

The Earth’s orbit around the Sun is called Revolution and takes 1 year.

Trade winds blow from east to west across the Pacific Ocean. The winds move surface waters westward across the ocean. This causes deeper, colder water to rise to the surface along the coast. This upwelling of deep ocean waters brings with it nutrients that would otherwise lie near the bottom of the ocean. Which of the following conclusions is supported by the information above? F Trade winds help maintain some food chains. G Trade winds produce useful minerals in some oceans. H Trade winds can reverse parts of the water cycle. J Trade winds may be able to reduce greenhouse gases.

F Trade winds help maintain some food chains.

The graph shows mercury levels found in sediments, prey animals, and adult shorebirds in a bay along the Gulf Coast. Which inference can best be drawn from these data? F The tide carried the mercury from South America. G The ocean currents brought the mercury to the Texas Coastline. H The mercury came from Mercury when an asteroid collided with the planet. J The Ocean breeze carried the mercury from South America.

G The ocean currents brought the mercury to the Texas Coastline.

The main difference between ocean water and lake water is that ocean water contains — A oxygen B salt C algae D plants

Ocean water contains SALT.

What carries warm water to the poles and cold water to the equator?

Ocean Currents

Tides are caused by the moon. What are they called and how many times do they appear during a 24 hour period?

There is High Tide and Low Tide and Texas generally has 2 within 24 hours Hide Tide Low Tide
