Question | Answer |
---|---|
What is a sand bar and how is it formed? | settled sand in a body of water, it is formed when the flow of water slows and the sand carried by the water settles |
What is a barrier island? | long narrow piles of sand that help protect the mainland from wave erosion |
What is a mesa and how is it formed? | a tall, flat topped rock feature formed as running water erodes the surrounding rock |
What is a canyon and how is it formed? | a deep valley with steep sides formed when rushing water carves through many layers of rock |
What is a moraine and how is it formed? | long low hills, formed by materiel carried by a glacier |
how is a glacial groove formed? | when a glacier scrapes and scratches the rock beneath it |
What is a landform? | a natural land shape or feature |
What is topography? | all the kinds of landforms in a certain place |
What is a glacier? | a large, thick sheet of ice |
What is a sand dune | a hill of sand, made and shaped by wind |
What is a delta and how is it formed? | an area of new land at the mouth of a river, formed by sediments carried by a river |
What is a sinkhole and how is it formed? | a large hole formed when the roof of a cave collapses |
What is the difference between erosion and weathering? | W: the rock is broken down E: the sediment is moved to other places |
What is a plate? | section of Earth's crust and upper mantle that fits together with other sections, like puzzle pieces |
What is a earthquake? | a shaking of the ground, caused by a sudden release of energy in Earth's crust |
What is an epicenter? | the point on earth's surface directly above the focus of an earthquake |
What is a fault? | a break in earth's crust |
What is magma? | molten rock beneath the earth's surface |
What is lava? | molten rock that reaches earth's surface |
What is a volcano? | a mountain made of lava, ash, or other materials from eruptions that occur at an opening in earth's crust |
What is the matter of the crust? | solid |

What is the inner core made of? | iron and nickel |
What are 3 ways mountains form? | 1. plates coming together 2. middle of the plate 3. plates move apart |
What are 3 ways earthquakes start? | 1. plates pushing together 2. sliding past each other 3. plates pulling apart |
How do scientists classify earthquakes? | by estimating their magnitude on a Richter scale |
Describe composite volcanoes | 1. wide with fairly steep slopes 2. made up of alternating layers of lava and ash |
Describe shield volcanoes | 1. broad volcanoes with gentle slopes 2. forms from lava that flows easily |
Describe cinder cone volcanoes | 1. tall, narrow, sleep slopes 2. made of rock, ash, and other solid materiels |
