1. Which event can rapidly change Earth's surface and is caused by an underwater earthquake?
a
hurricane
b
tornado
c
tsunami
d
whirlpool
2. How does erosion compare to physical weathering?
a
Both break down materials.
b
Both move materials from place to place.
c
Erosion breaks down materials, and weathering carries them from place to place.
d
Weathering breaks down materials, and erosion carries them from place to place.
3. Living organisms are found on what layer of Earth?
a
the mantle
b
the core
c
the crust
d
the inner core
4. The lithosphere is one of Earth's layers. What makes up the lithosphere?
a
the inner and outer cores
b
the upper and lower mantle
c
the mantle and outer core
d
the crust and upper mantle
5. What has to be present in order for metamorphic rocks to form?
a
melting and cooling This is the result of incorrectly thinking metamorphic rocks form due to the process that forms magma and igneous rock.
b
heat and pressure This is correct. When igneous and sedimentary rocks experience extreme heat and pressure, they transform into metamorphic rock.
c
weathering and erosion This is the result of incorrectly thinking metamorphic rocks form due to the process that forms sediments.
d
compaction and sedimentation This is the result of incorrectly thinking metamorphic rocks form due to the process that forms sedimentary rocks.
1. Correct Answer: c) tsunami
Well, when there's an underwater earthquake, it must be feeling a bit shaky down there. So, it decides to give Earth's surface a good old shake-up, causing a tsunami!
2. Correct Answer: d) Weathering breaks down materials, and erosion carries them from place to place.
Erosion and weathering are like the dynamic duo of Earth's surface. Weathering breaks down rocks and other materials, while erosion swoops in to carry them away. It's a real teamwork affair!
3. Correct Answer: c) the crust
Ah, the layer where all the action happens! The crust of the Earth is where you'll find living organisms. It's like a bustling neighborhood, but with more worms and less noise complaints.
4. Correct Answer: d) the crust and upper mantle
The lithosphere is like the cool club where only crust and upper mantle rocks get in. They hang out together, forming a strong and rigid layer. Who knew rocks had such exclusive clubs?
5. Correct Answer: b) heat and pressure
Metamorphic rocks like to transform and show off their new looks. But to do that, they need a makeover involving extreme heat and pressure. It's like their version of a spa day, but with a lot more rock involved!
Hope I could help, even if it was with a touch of humor!
1. The event that can rapidly change Earth's surface and is caused by an underwater earthquake is a tsunami. To determine the correct answer, we need to understand what a tsunami is. A tsunami is a series of powerful ocean waves caused by the displacement of a large volume of water, usually from an underwater earthquake.
2. To compare erosion and physical weathering, we need to understand what each process involves. Physical weathering refers to the breaking down of rocks and minerals through mechanical forces like freezing and thawing, abrasion, and root wedging. Erosion, on the other hand, involves the movement of weathered materials from one place to another through agents like water, wind, or ice. Based on these definitions, we can conclude that erosion breaks down materials (by moving them) and weathering carries them from place to place.
3. To determine where living organisms are found on Earth, we need to understand the different layers of the planet. Earth consists of several layers, including the crust, mantle, outer core, and inner core. Living organisms are primarily found on the Earth's crust, the outermost layer that supports life.
4. The lithosphere is a layer of Earth's structure. To determine what makes up the lithosphere, we need to understand its composition. The lithosphere is composed of the crust and the uppermost part of the mantle. Therefore, the correct answer is that the crust and the upper mantle make up the lithosphere.
5. In order for metamorphic rocks to form, certain conditions need to be present. Based on our knowledge of rock formation processes, we can eliminate options a, c, and d. Melting and cooling form magma and igneous rocks, weathering and erosion form sediments, and compaction and sedimentation form sedimentary rocks. The correct answer is option b, which states that heat and pressure are required for the formation of metamorphic rocks. When igneous or sedimentary rocks are exposed to extreme heat and pressure, they undergo changes in mineral composition and texture, transforming into metamorphic rocks.
1. The event that can rapidly change Earth's surface and is caused by an underwater earthquake is a tsunami (option C).
2. Weathering breaks down materials, and erosion carries them from place to place (option D).
3. Living organisms are found on the crust of Earth (option C).
4. The lithosphere is made up of the crust and the upper mantle (option D).
5. Metamorphic rocks form due to heat and pressure (option B). When igneous and sedimentary rocks experience extreme heat and pressure, they transform into metamorphic rock.
